How to Get a PO Box: Step-by-Step Guide for USPS and Private Providers

• 40 min read

Introduction:

Renting a post office box (P.O. Box) is a convenient way to securely receive mail at a dedicated address other than your home. Whether you want extra privacy for personal mail or a professional mailing address for a business, a PO box can be a useful solution. This comprehensive guide explains why you might want a PO box, the types of PO box providers (USPS vs private services), how sizes and pricing compare, and provides step-by-step instructions to rent one. We’ll also compare the pros and cons of USPS PO boxes versus private mailboxes, highlight additional services (like mail forwarding and 24/7 access), and offer tips for choosing the best option for your needs.

Why Get a PO Box?

There are several reasons people opt for a PO box instead of receiving mail at their home or office:

  • Privacy for Your Home Address: A PO box helps keep your personal home address confidential. Instead of giving out your residential address, you can use the PO box for mail and packages, which adds a layer of privacy and security. This is popular with home-based business owners and anyone who doesn’t want customers or strangers knowing their home location.

  • Mail Security: Mail delivered to a PO box stays in a locked box inside a secure post office facility, safe from porch pirates or identity thieves. Unlike a mailbox on your porch, which could be tampered with, a PO box is accessible only with your key or combination inside a monitored postal lobby. Important documents, checks, and packages remain much more secure in a PO box than left at your doorstep.

  • Business Use & Professionalism: Many small businesses and freelancers use PO boxes to separate business mail from personal mail and to have a consistent mailing address. It can provide a stable business address even if you work from home or move offices. Having an official mailing address lends some professionalism, although as we’ll discuss later, using a PO box has limitations for business image.

  • Permanent Address for Frequent Movers or Travelers: If you move frequently, live in an area without reliable mail delivery, or travel for extended periods, a PO box gives you a permanent mailing address. You won’t have to constantly change your mailing address or worry about mail piling up at home while you’re away. All your mail can go to one secure location and wait for you.

  • Faster Mail Delivery: Because PO boxes are located at the post office, mail often gets into your box faster than home delivery. There’s no extra routing on a mail carrier’s route - once the post office receives your mail, they place it directly in your box the same day. This can mean receiving important letters or packages slightly sooner.

In summary, people choose PO boxes for the security, privacy, and convenience of a locked mail receptacle that’s not tied to their home. It’s especially useful for those concerned about identity theft, those running a small business from home, or anyone needing a stable mailing address separate from their residence.

PO Box Provider Options: USPS vs. Private Mailbox Services

When considering a PO box, you have a few provider options. The two main categories are USPS PO boxes (rented from the U.S. Postal Service at a post office) and private mailbox providers (e.g. a mailbox at a UPS Store or other independent mail centers). There are also virtual mailbox services that provide a mailing address and digital mail handling. Here’s an overview of each:

  • USPS PO Boxes: A traditional PO box is offered by the United States Postal Service and located in a post office facility, usually a post office near you. You receive a lockable box with an address format “PO Box [number]”. Historically, people got USPS PO boxes if mail wasn’t delivered to their home, but today many use them for extra security or privacy. Getting a USPS PO box is straightforward - you choose a post office location, fill out an application, pick a box size, and pay the rental fee to get your keys. Important: USPS PO boxes only accept USPS mail by default; packages sent via UPS, FedEx, or other carriers will not be delivered to a USPS PO box address (we’ll discuss a workaround for this in the services section). Also, a USPS PO box provides an address but not a real street address, which means you typically cannot use a PO box for official business registration or some financial accounts that require a physical address.

  • Private Mailbox Providers (e.g. UPS Store, Mail Centers): Private companies like The UPS Store or local mailbox shops rent mailbox services that function similarly to PO boxes, but with some differences. A UPS Store mailbox is a lockable box at their retail location (often referred to as a CMRA - Commercial Mail Receiving Agency). Unlike a USPS PO box, a private mailbox comes with a real street address. Your address will be the store’s street address plus a suite or box number (often formatted as “#123” or “PMB 123”) instead of a PO box line. This means you can receive packages from any carrier - USPS, UPS, FedEx, DHL, etc., are all accepted at a UPS Store mailbox. For many, this is a big advantage over USPS. The UPS Store (and similar providers) also often offer longer business hours or even 24-hour access for you to retrieve mail, and they may provide services like notifying you when you receive mail. The sign-up process for a private mailbox is similar in that you need to provide ID and sign a rental agreement, but you’ll do this directly with the store. One thing to note is that private mailbox services usually cost more than a USPS PO box of comparable size (because of the added services and that you’re paying a private business). We’ll compare pricing later.

  • Virtual Mailbox Services: Beyond physical PO boxes, there are now virtual mailbox providers (like iPostal1, Anytime Mailbox, Traveling Mailbox, etc.) which give you a real street address but also manage your mail digitally. You choose an address (often a real mailing address at a mail center or office) and the service will receive your mail, scan envelopes, and even open and scan the contents for you to view online, or forward items to you as needed. Virtual mailboxes let you manage mail remotely via an app or website - ideal for people who are frequently traveling or who want to eliminate physical mail handling. They can be used for business or personal mail and are generally more expensive than a basic PO box, but they offer convenience and remote access. (For example, some virtual mailbox plans range from around $10 up to $50+ per month depending on volume and features.) If you truly never want to visit a mailbox in person, a virtual mailbox is an alternative to consider. However, in this guide we’ll focus on the physical PO boxes (USPS or private) since the process to get those is different.

In summary, USPS PO boxes are run by the government postal service, usually the most affordable option but with limitations on package carriers and address type. Private mailboxes (UPS Store or others) act like a PO box with a street address, allowing more flexibility (all carriers, professional address), at a higher cost. Virtual mailboxes are a modern option for digital mail management, and a popular choice for registering a business. Next, let’s look at how PO box sizes and prices compare across these options.

PO Box Sizes and Pricing Comparison

PO Box Sizes: USPS and private mailbox providers offer various box sizes to accommodate different needs. USPS typically has 5 standard PO box sizes, often labeled 1 through 5 or described as Extra Small through Extra Large. Here are the common dimensions and what they hold:

  • Extra Small (3” x 5.5” x 14.75”) - Fits about 10-15 letter envelopes or a couple of rolled magazines. This is good if you only expect a very small volume of mail (no packages).

  • Small (5” x 5.5” x 14.75”) - Fits around 15-20 letters or up to five rolled magazines. Still primarily for letters, though slightly more capacity.

  • Medium (11” x 5.5” x 14.75”) - About the width of a letter but much deeper. It can hold larger envelopes (flats) or a stack of magazines laid flat. Good for moderate mail volume.

  • Large (11” x 11” x 14.75”) - Nearly a square foot of space; can fit larger parcels or about two small package boxes plus letters. Suitable if you receive small packages occasionally in addition to mail.

  • Extra Large (22.5” x 12” x 14.75”) - The biggest box available; can fit most Priority Mail Large Flat Rate boxes or similarly sized packages. Useful for businesses or individuals receiving multiple packages regularly.

(Note: Private mailbox providers may use terms like Small/Medium/Large and their exact dimensions can vary by provider. Generally, they correspond in capacity to the USPS sizes above, though some private centers might not offer an “Extra Small” or “Extra Large” if there’s low demand. It’s best to check with the specific location.)

Pricing: The cost of a PO box depends on which provider you choose, the box size, the location, and the rental term (length of contract). Below is a comparison of typical price ranges:

  • USPS PO Box Cost: USPS rates are relatively affordable. For example, a small USPS PO box can cost as little as about $4-$6 per month in a low-cost area, whereas an extra-large box might be around $20-$30 per month in a high-cost urban post office. USPS actually sets prices in tiers based on the location (busy city post offices cost more than rural ones) and you usually pay for 3, 6, or 12 months at a time. According to USPS, the smallest size box can be under $5 monthly (when averaged over a long term) and the largest size around $24+ monthly. Keep in mind you often must pay 3 or 6 months upfront when first renting, not month-to-month. For the most accurate pricing, you can use the USPS website to find the exact fees at your nearest post office.

  • Private Mailbox (UPS Store) Cost: Private mailbox providers charge more, and prices vary by location/market. A common range for a UPS Store mailbox is about $10 to $30 per month for a small box, and around $30 to $50 per month for a large box, depending on the store and region. Medium sizes typically fall in between (e.g. ~$20-$40/month). These rates also may be offered at discounts if you pay for a longer term (e.g. 6 or 12 months in advance). Each UPS Store is individually owned, so pricing isn’t uniform nationwide - a mailbox in New York City will cost more than one in a small town. Private centers might also require a one-time setup fee or key deposit. Always check with the specific provider for their pricing sheet.

  • Virtual Mailbox Cost: Virtual mailbox services usually charge monthly and have tiered plans. Basic plans can start around $10-$15 per month for low volume (just a few mail items), but for robust services (high mail volume, multiple recipients, frequent scans/forwards) it can go $10-$50+ per month with Anytime Mailbox. Some premium virtual services for businesses are even higher (for example, Stable offers virtual mailbox plans from $49 up to $89 monthly). Keep in mind virtual services might charge extra per item scanned or forwarded, whereas a physical PO box has a fixed rent regardless of how much mail you receive (aside from overflow issues).

Tip: Consider how much mail and packages you expect to receive when choosing a size and evaluate your budget for these recurring costs. USPS will almost always be cheaper for a given size, but the trade-offs might make a private box worth the extra money if you need those features. Next, we’ll walk through how to rent a PO box step by step.

How to Rent a PO Box: Step-by-Step Instructions

Renting a PO box (especially a USPS PO box) is a straightforward process. You can complete the application online for USPS or do it in person. Below are the steps to get a PO box, including what documents you need and the differences between online and in-person registration. We’ll focus on USPS PO boxes in these steps, but we’ll note where the process is similar or different for private providers.

1. Choose a Location for Your PO Box

The first step is deciding where you want your PO box. Typically, you’ll want a post office or mailbox center that’s convenient to your home or work for easy mail pickup. For USPS PO boxes, you can use the USPS website’s PO Box locator to find post office locations near you that have PO boxes available. You can even get a box in another city or state if you have a specific reason, but remember you’ll need to visit that post office in person to complete the signup and pick up your keys. Keys will not be mailed to you. So, practically, most people choose a nearby post office. If one post office is full or has a waitlist for boxes, you might need to choose an alternate location or join their waiting list (popular locations can run out of certain box sizes).

For a private mailbox like at The UPS Store, you should locate a nearby store and ensure they offer mailbox services (most do). You will generally have to visit the store to sign up. (Some private mailbox providers allow you to reserve or inquire about a box online or by phone, but finalizing usually requires going in to show ID and sign forms.)

2. Pick the Right Box Size

Next, determine what size mailbox you need. Refer to the size options discussed earlier. If you only expect letters and very small parcels, a smaller box will do. If you run a business or expect larger packages, opt for a medium or large box so you don’t constantly overflow. USPS offers up to five sizes (XS through XL), but not every post office has all sizes available at all times, so you may need to be flexible. You can check size availability on the USPS website when reserving, or ask at the post office counter. It helps to estimate your typical weekly mail volume: for example, a small PO box might hold a week or two of personal mail, but if you get lots of magazines or packages, you’d need a bigger size. Remember, if you choose too small a box and it overflows frequently, USPS may ask you to upgrade to a larger box or risk mail being returned.

3. Complete the Application (Online or In Person)

For a USPS PO Box: You have two ways to apply - online via the USPS website or in person at the post office.

  • Online Application: Visit the USPS “PO Boxes” page and use their online reservation system. You’ll search for your desired post office location, select an available box size, and choose your rental term (3, 6, or 12 months). The system will then prompt you to pay for the box online with a credit or debit card. This reserves the box for you. Keep in mind: even after paying online, the box is not fully yours until you visit the post office to show ID and pick up the keys (you typically have 30 days to do this). The online process is convenient for reserving a box and ensuring you get the size you want, but it doesn’t skip the identity verification step.

  • In-Person Application: If you prefer, you can go to the post office you want the box at, and fill out the form on the spot. The required form for USPS is PS Form 1093 - Application for PO Box Service. Post offices usually have these forms available in the lobby. You can also print the form at home (from the USPS website) and fill it out beforehand to save time. At the counter, you’ll submit the form to a clerk, who will check which sizes are available, ask you to pay the rental fee, and then handle the ID verification (see next step). In-person has the advantage that the clerk can tell you immediately which boxes are open and you walk out with your keys same-day if all goes well. Payment in person can usually be made by cash, check, or card.

For a Private Mailbox (UPS Store or others): The application isn’t standardized like USPS, but generally you will need to visit the store and fill out their rental agreement (often called a Mailbox Service Agreement). Similar to USPS, you will also need to complete Form 1583 for the USPS - this is a form that authorizes a Commercial Mail Receiving Agency (CMRA) to receive mail on your behalf. The store will provide this form, and it requires your identifying information and a notarized signature (if not signed in person in front of them). If you’re signing up at the store, the staff will usually handle the notarization by witnessing your signature with your IDs. So effectively, at a UPS Store you’ll fill out two forms: the store’s own rental agreement and USPS Form 1583 (for mail authorization). Some UPS Stores let you start the process online by submitting a request, but you’ll still have to go in to show IDs and sign. Plan to pay the rental fee and possibly a key deposit or setup fee when you apply.

4. Provide Required Identification and Documents

Whether you apply online or in person, you must visit the post office (or mailbox provider) in person to show identification and finalize the rental. Two forms of ID are required for a USPS PO box, and the same rule applies for private mailbox rentals (per USPS regulations for CMRAs). The identification requirements are:

  • Primary ID: A government-issued photo ID that proves your identity. Acceptable examples include a valid driver’s license or state ID card, a passport, military ID, alien registration (green card), or other government-issued photo IDs. The ID must be current (not expired) and have enough information (like name, photo, etc.) to identify you.

  • Secondary ID: An ID or document that confirms your physical address or some additional information. This does not need to have a photo, but it should have your name and address. Common examples are a utility bill, lease or mortgage document, voter registration card, vehicle registration, home or auto insurance policy, etc.. The secondary ID is used to verify the address you put on your PO Box application (which should be your current physical residence or business address - note that the USPS wants to know where you live, even though you’re renting a PO box). Social Security cards, credit cards, birth certificates, and similar items are NOT accepted as IDs for a PO box. You need tangible IDs that can be traced back to you.

When you go to the post office to show your IDs, also bring your PS Form 1093 (if you applied online, print the confirmation or bring the form you filled) and the confirmation receipt if you paid online. The clerk will verify your IDs, have you sign the form, and then issue your PO box keys. If you are applying at a private mailbox provider, bring the two IDs as well - they will make copies to keep with your Form 1583 on file (as required by law).

Important: If you did the online reservation for a USPS box, you have 30 days from the online sign-up to present your IDs at that post office. If you miss that window, the reservation may be canceled. So don’t forget this step!

5. Pay the Rental Fee and Get Your Keys

For USPS, if you applied in person you will pay the rental fee at the counter (USPS accepts cash, check, credit/debit) for the term you choose, and a refundable key deposit if applicable (usually USPS provides 2 keys for free and charges a small fee if you want a third key or if you lose keys). If you applied online, you would have already paid, so you would just show your ID and the payment is confirmed in their system. The post office staff will then give you your PO box address, number, and keys - typically two keys for the box. Test them out to make sure they work, and sign any final acknowledgment if required. Now your PO box is active and you can start using that address for your mail !

At a UPS Store or private mailbox, you’ll pay the agreed rental rate (and usually a one-time fee for keys or setup). They will then assign you a mailbox number and give you the keys to that mailbox. The staff should explain how you or senders should format the mailing address. For example, at UPS your mailing address will be something like:

[Your Name]  
#123 (or PMB 123)  
12345 Street Name  
City, State ZIP

They might also give you a copy of the mailbox service agreement for your records. Once you have the keys, you’re all set to receive mail at your new address.

6. Redirect Your Mail (Change of Address) [Optional]

If you were previously receiving mail at a different address and want it all to come to your new PO box, you should file a Change of Address form. For USPS, you can do this online or via a paper form (PS Form 3575) to forward mail from your old address to the new PO box. This will ensure mail sent to your old address gets automatically rerouted into your PO box for a period of time (usually 12 months for mail forwarding). If you don’t do this, you’ll need to directly inform senders of your new address. For a business, update your mailing address with banks, clients, vendors, etc. If you got a private mailbox, likewise inform senders of the new address. (There isn’t a formal USPS change-of-address to a private CMRA address, since it’s not USPS-managed, but your private provider can often help forward any stray mail from an old address if needed.)

After completing these steps, you should now have a functioning PO box to receive mail. Make sure to regularly check your box or arrange for forwarding so it doesn’t overflow. Next, we’ll compare the pros and cons of using a USPS PO box versus a private mailbox service, to help you weigh which is better for your situation.

USPS PO Boxes vs. Private Mailboxes: Pros and Cons

Both USPS and private mailbox providers offer secure mailboxes, but they have different advantages and disadvantages. Here’s a breakdown:

✅ Advantages of a USPS PO Box

  • Affordability: USPS PO boxes are generally cheaper than private options. They can cost as little as $4-$5 per month for a small box in some locations. If budget is a primary concern and you don’t need extra services, USPS is the cost-effective choice.

  • Widespread Convenience: There are post offices in almost every town, often more numerous than private mail centers. You can likely find a USPS location nearby, which makes it convenient to access your mail. Also, if you ever move within the U.S., there’s probably a USPS post office in your new area where you could get a box.

  • Security and Reliability: USPS facilities are secure, federal buildings. Your PO box is inside a locked postal lobby, which is generally very safe. Mail in a USPS box is under USPS security measures and not accessible to anyone without a key. This is a secure way to get mail and avoid mail theft.

  • Fast USPS Delivery: Mail sent via USPS often arrives in your PO box slightly faster than to street addresses in the same town (since it doesn’t have to be carried out on a route). Also, USPS will hold your larger packages at the post office for pickup if they don’t fit in the box, ensuring you don’t miss deliveries (they’ll leave a notice in your box).

  • Privacy/Stability: Using a PO box means you never have to give out your home address. This keeps your residence private and separate from your public mail. It also provides a stable mailing address if you anticipate changing residences - you can keep the same PO box address for years, even if you move around locally.

  • Flexible Rental Terms: USPS lets you rent for 3, 6, or 12 months at a time, which gives some flexibility. If you only need a box for a short-term (like 3 months), you can do that and renew as needed.

  • Anonymity: If you prefer not interacting with people when picking up mail, a PO box is fairly anonymous. You just go to your box and use your key; there’s no need to wait in line unless you have a pickup notice.

(Note: Some of these “pros” apply to private mailboxes too, such as security and privacy, but they are core strengths of USPS PO boxes particularly.)

❌ Disadvantages of a USPS PO Box

  • Only Receives USPS Mail: A big limitation is that a USPS PO box cannot receive packages from UPS, FedEx, DHL, or other non-USPS couriers (they will be refused or returned). If someone tries to send you something via FedEx to your PO box address, it won’t get delivered. This is problematic if you frequently order online from retailers that ship by UPS/FedEx or if you expect important courier deliveries. (There is a workaround: USPS now offers a “Street Addressing” service for PO boxes - see Additional Services below - but it requires using the post office’s street address and is only at certain locations.)

  • Not a Physical Street Address: A PO box address is not a real street address, which means you cannot use it for certain purposes. Many government forms, banks, and services (like driver’s license or business registration) require a physical address and will not accept a PO Box number. For example, when registering an LLC or corporation, states usually require a registered agent street address - a PO box won’t satisfy that. Also, some merchants and credit card companies might not accept a PO box for the “billing address” or shipping address fields. This lack of a street address can be limiting, especially for business use, and can also look unprofessional on business correspondence.

  • Perception and Legitimacy: Related to the above, using a PO Box for a business may appear less credible to some clients or customers. People sometimes associate PO boxes with transient or less-established entities (e.g., a scammer or hobbyist) compared to a real street address. This is a perception issue: while plenty of legitimate businesses use PO boxes, you should be aware of the potential image concern if you’re using it as your public business address.

  • In-Person Pickup & Limited Access Hours: With a physical PO box, you (or someone from your business) must physically go check the box to retrieve mail. This can be inconvenient if you’re busy or traveling. Some post offices offer 24/7 lobby access to PO boxes, but many smaller post offices only have lobby hours during the day (e.g., 8am-6pm) and closed on Sundays/holidays. If your schedule doesn’t align, it may be hard to get your mail on time. There’s no after-hours access if the lobby is locked. USPS does not, by default, notify you when you have new mail - it’s on you to check regularly.

  • No Included Forwarding or Remote Services: USPS will not automatically forward your mail from a PO box to another address unless you pay for a separate Premium Forwarding service or closing your box and file a change of address. There’s no built-in scanning or emailing of your mail. If you can’t check your box often, you might miss time-sensitive mail. (USPS’s Informed Delivery service can send you a daily email with images of your incoming letter-sized mail, which can help you know what’s coming, but it’s not a substitute for actually collecting your mail and doesn’t apply to packages.) In short, USPS PO boxes are a very manual service.

  • Size Limitations and Overflow: You are limited by the physical size of your box. If you get a lot of mail or any large envelopes, a small box can fill up quickly. Once it’s full, additional mail might be held at the counter or even returned to sender if not picked up promptly. While you can always upgrade to a bigger box (if available) or empty it more often, that’s an extra hassle and possibly cost.

  • Availability Issues: In some popular locations, especially in busy cities or neighborhoods, PO boxes can have a waitlist because demand exceeds supply. You might not immediately get the box size or location you want and could be stuck waiting or checking back.

Despite these cons, many individuals and small businesses find USPS PO boxes perfectly sufficient for their needs, especially if cost is a priority and they primarily deal with USPS mail.

✅ Advantages of a Private Mailbox (UPS Store or Similar)

  • Real Street Address: The biggest selling point of a private mailbox is that it provides you with a real street address rather than a “PO Box” number. This means you can use it for almost any situation that requires an address. You can put it on your business cards and website without the stigma of a PO box. For business owners, it gives a more professional image. You can also use it as the address for registering your business, receiving official documents, or as a billing address, since it looks like a standard address.

  • Accepts All Mail Carriers: Private mailbox services will accept deliveries from all carriers (USPS, UPS, FedEx, DHL, Amazon, etc.) on your behalf. You aren’t limited to just USPS mail. This is a huge advantage if you frequently get packages from different couriers. You can send everything to one address and know it will be signed for and received, regardless of who is delivering it.

  • Package Handling and Notification: Services like The UPS Store often include package signing and notification. When a package arrives for you, the staff signs for it and secures it until you pick it up. Many locations will then notify you (via email or text) that you have a package or mail waiting. This saves you unnecessary trips - you’ll know when something important has arrived. USPS, by contrast, doesn’t notify you unless you subscribe to certain add-ons or check Informed Delivery.

  • Extended Hours / 24-7 Access: Private mailbox locations often offer extended pickup hours. Many UPS Store locations provide 24-hour access to the mailbox area for customers, or at least early morning and late evening hours beyond the typical post office schedule. So if you can’t get there until 10pm, that might be fine at a UPS Store with 24/7 lobby access (you might have a keycard to enter the store after hours). This flexibility is great for people who work irregular hours.

  • Mail Forwarding and Holding Services: Most private mailbox providers will, upon request, forward your mail to another address if you can’t pick it up regularly (for example, if you move or are on a long trip). They usually charge an extra fee for postage and a small service fee, but it’s convenient. They will also hold your mail securely if you’re away for a while. USPS will also hold mail if you ask, but the private mailbox is a one-stop shop for these additional services.

  • Multiple Recipient Names: Private mailboxes generally allow you to receive mail for multiple names (e.g., your business name, your personal name, your spouse) under one mailbox agreement without extra cost. USPS also allows this to some extent (you can list individuals on your PO box), but private centers might be more flexible with receiving for various business trade names, etc.

  • Customer Service and Extras: At a private mail center, the staff is there to help as part of their service. You can often call them to check if you have new mail (UPS calls this “Call-in MailCheck®”), and they’ll tell you if there’s anything in your box. Some might even discard junk mail for you on request. Also, since these stores offer other services (shipping, supplies, printing), you can tackle multiple errands in one stop.

In short, private mailbox providers offer greater flexibility and services than a standard PO box - you get a true street address, broader mail/package acceptance, notifications, and service conveniences, making it almost like having a small office mailbox.

❌ Disadvantages of a Private Mailbox

  • Higher Cost: The added benefits come at a price. Private mailboxes can cost significantly more per month than a USPS PO box of equivalent size - sometimes double or more. Over a year, that difference can add up. If you’re on a tight budget and don’t absolutely need the extra services, the cost might be hard to justify.

  • Variable Availability & Terms: Since each location is individually operated, you might find varying policies. Not every town has a good private mailbox provider, whereas USPS is everywhere. If you move, you can’t “transfer” your UPS Store mailbox to a new city; you’d have to open a new one and close the old (possibly paying new setup fees). Also, contract lengths can vary - some require a 6-month minimum, others 3-month - it’s not standardized.

  • In-Person Requirement (Unless Forwarding): Just like a PO box, you still have to go pick up your mail unless you pay for forwarding. So if you’re far away or very busy, you might end up paying for mail forwarding on top of the mailbox fee, which increases cost. It’s not as “hands-off” as a virtual mailbox service (though the notifications help). Essentially, the same inconvenience of physically collecting mail applies, unless you take extra steps.

  • Perception/Legitimacy Issues (Minor): While a street address from a UPS Store looks more legit than a PO Box, savvy individuals can sometimes recognize the address belongs to a UPS Store or mail center (for example, if they Google the address). Some customers or partners might realize it’s not your actual office. A UPS Store address could potentially confuse people or raise questions if they expected your business to have a standalone location. This is a minor issue and usually not a deal-breaker, but it’s worth noting that using a known mail center address isn’t the same as having your own office suite.

  • Security and Privacy: While rare, there have been instances of mail theft or issues at private mail centers (e.g., if an unscrupulous employee mishandles mail). USPS has very strict federal protections for mail. With a private provider, you’re trusting that franchise/store to be secure. In general, UPS Stores are safe, but they don’t have the same level of federal oversight. Also, private centers might close on some holidays or for emergencies when the franchise owner decides, whereas USPS has more consistent hours.

  • Extra Fees for Services: Many of the “pros” (forwarding, call-in check, etc.) come with additional fees or only upon request. For instance, mail forwarding might have a base service charge plus postage costs. If you lose your key, there’s a replacement fee (same with USPS though). Some stores charge for notifying beyond a certain number of alerts, etc. So make sure you understand the fee schedule.

In summary, a private mailbox is ideal if you need a versatile, full-service receiving address and are willing to pay more for it. A USPS PO box is great if you just need a basic, low-cost mailbox and primarily deal with USPS mail. Your choice will depend on what features matter most to you.

Additional Services and Features to Consider

When choosing between USPS and private mailbox providers, also consider the extra services and features that each may offer beyond simply holding your mail:

  • Street Addressing for USPS PO Boxes: As mentioned, USPS now offers a service called Street Addressing at many post offices. This lets you use the street address of the post office plus your box number (formatted like a suite) instead of a PO box address. For example, if your post office is at 500 Main Street and your PO box is 123, you can receive mail addressed to “500 Main Street #123, [City, State ZIP]”. This can trick some private carriers into delivering, and USPS will route that mail to your PO box. The Street Addressing option specifically allows customers to receive packages from UPS, FedEx, and others that normally won’t deliver to a “PO Box”. Important: You usually must sign up for this service by signing a form at the post office (often part of “Premium PO Box Services”). It’s free, but not all post offices offer it - check if your location supports street addressing. If you do use it, note that you shouldn’t also file a change-of-address from the PO box to the street address (since they are essentially the same box). Street addressing can be a game-changer if you have a USPS PO box but want to receive occasional UPS/FedEx shipments - just ensure the shipper will accept the street format.

  • Mail Forwarding Services: If you can’t regularly check your mailbox, forwarding is useful. USPS PO Boxes do not include free forwarding, but you can pay for Premium Forwarding Service which will weekly package up your PO box mail and send it to another address (for a hefty fee), or you can close the box and forward mail via change-of-address (not ideal for short term). Some users simply ask a friend or family member who has access to grab their mail. In contrast, private mailbox providers often offer mail forwarding on-demand. You can arrange to have your mail bundled and sent to you at a different address, paying any postage and a service fee. This is great for winter visitors (snowbirds) or business owners who can’t visit the box often. If mail forwarding is important, a private provider might be more accommodating. (Virtual mailbox services by nature will forward or scan mail as you instruct, since remote management is their core offering.)

  • Package Acceptance & Notification: As covered, private mailboxes accept packages from all carriers by default. USPS PO boxes will only automatically accept USPS packages; any FedEx/UPS that slip in via street addressing is a bonus. Package notification is another feature - UPS Store mailboxes typically include notifying you (text, email, or a phone call) when a package arrives. Some USPS post offices have begun offering email notifications for PO box holders as part of “PO Box Plus” services, but it’s not widespread. If you want to be sure you never miss a package, a private service that actively notifies you is helpful.

  • 24/7 Access: Check the lobby hours of the location. Many USPS post offices provide 24/7 lobby access to the PO boxes (especially larger locations or those co-located with distribution facilities). Others might lock the lobby at night for security. UPS Stores that are in 24-hour retail locations or strip malls sometimes provide 24-hour access to mailbox customers via an exterior door code or key card. In other cases, they might only allow access during store business hours (which still could be 8am-8pm, longer than a typical post office). So, if round-the-clock access matters because you might need to pick up mail at odd hours, inquire about that.

  • Mail Holding/Vacation Services: USPS allows you to put a PO box on hold if you won’t be collecting mail for a while (they typically just hold overflow at the post office until you return, since the mail won’t be delivered anywhere else anyway). Private providers often explicitly offer to hold your mail securely if you’re away and not forwarding. This is usually not an extra charge - it just means they won’t mark your box as overflowing. It’s essentially part of the service to keep your mail safe until you can get it.

  • Number of Users/Names: USPS lets you receive mail for yourself and immediate family or others if you list their names on the application. Private mailbox agreements often allow multiple recipients (personal or business names) as well. If you need a box for multiple people (like roommates or multiple business names), clarify any limits. Some private CMRAs might charge a small fee for additional names.

  • Additional Retail Services: At a private mailbox provider, you might get a one-stop shop: shipping services, notary public, copying/printing, etc. This can be convenient if you frequently need those services; you can handle mail and shipments together.

  • Insurance and Liability: Generally, USPS’s liability for lost mail ends once it’s in your PO box (and they rarely lose stuff placed in a locked box). Private providers typically have you sign that they aren’t liable for lost/damaged mail either, though they will do their best. Some virtual mailbox and CMRA services offer optional insurance for mail items, etc. For extremely sensitive or valuable mail, consider certified mail or other tracking to the box.

In essence, USPS PO boxes are a no-frills service - secure and straightforward, with a couple of newer perks like street addressing. Private mailboxes act more like a full-service mail concierge, often with a suite of helpful services (for a price). Consider which of these extras you genuinely need so you don’t pay for what you won’t use.

Tips for Selecting the Best PO Box Provider for Your Needs

With all the information above, you should consider the following factors to decide between a USPS PO box, a private mailbox, or other solutions:

  • Purpose (Personal vs Business): If it’s personal use (e.g., privacy for your mail, security, or having a permanent address while between homes), a USPS PO box will cover the basics at lowest cost. If it’s for business, think about the image and functional needs. A business may lean towards a private mailbox if you want to use it as your public business address or need to receive various courier packages regularly. Also, check legal requirements: businesses often need a physical address for registration - a UPS Store address can suffice, but a USPS PO box will not.

  • Mail and Package Volume: Estimate how much mail and packages you receive. Low volume and only USPS mail - USPS PO box should be fine. High volume or many packages from Amazon, FedEx, etc. - a private mailbox might be worth it to handle all those deliveries. If you expect frequent large packages, ensure the box size or service can accommodate them (or hold them). You might choose a larger box or a provider who will hold overflow packages without issue.

  • Budget: This can be a deciding factor. USPS is typically cheapest. If your budget is tight, start with a USPS small box if it meets your needs. If you have flexibility and the features of a private box are compelling, weigh the monthly cost difference. Also factor in the value of your time: if driving to a post office across town daily is impractical, paying more for a closer or more convenient private box might pay off. Always compare the total cost for the term you want (some USPS locations might be surprisingly affordable or expensive, so check). Remember to consider any deposit or key fees and the cost of extra services (like forwarding fees) you might use.

  • Location and Convenience: Is the post office or UPS Store on your daily commute or near places you frequent? The easier it is to access, the better. If the nearest post office with an available box is far but there’s a mailbox store next door, convenience might trump cost. Also check hours: a post office with 24/7 access vs. a UPS Store that closes at 6pm might make a difference if you need late access, or vice versa. Choose a provider whose access hours align with your schedule.

  • Duration of Need: Are you looking for a short-term solution (e.g., 3-6 months while between addresses) or a long-term mail solution? USPS offers short rental terms easily. Private stores might prefer longer sign-ups but usually allow 3-month minimums. If it’s very short-term, see if a friend’s address or a temporary forwarding might even suffice instead of renting a box. For long-term, consider future needs: you might start with personal use but anticipate registering a business later - maybe go with a private box from the start that you can use for both personal and business to avoid changing addresses.

  • Privacy and Anonymity Needs: If keeping your name out of directories is a concern, note that when you rent a USPS PO Box, your identity (name and address) is kept on file by USPS but not publicly available. Private mailbox centers are required to keep Form 1583 on file with your info, but again it’s not public. However, if someone sends a certified letter to your PO box, they’ll learn your name, etc. If you require extreme anonymity, a virtual mailbox or a forwarding service might actually be better, as they can forward mail to you without you ever stepping into a location.

  • Special Features: Decide which special features are must-haves:

  • Need to get UPS/FedEx packages often? Choose a private mailbox or ensure USPS street addressing is available and reliable at your post office.

  • Want notifications when mail arrives? Lean private mailbox (or a virtual service that will notify you).

  • Require 24/7 access? Check your local post offices for 24-hour lobbies, or see if a nearby UPS Store offers after-hours access.

  • Plan to forward mail regularly to another location? Private mailbox services have established forwarding (UPS Store can forward “anywhere you are” for an extra charge ), whereas USPS would require using premium forwarding or doing it yourself.

  • Need scanned copies or digital handling? Consider a virtual mailbox service instead of a physical PO box, since neither USPS nor UPS will scan and email your letters as a standard practice (though some independent mail centers might for a fee).

  • Compare Reviews and Policies: If you opt for a private provider, it can help to read reviews of that particular location. Quality of service can vary - some UPS Store franchises are excellent with customer service and notifications, others maybe less so. Make sure they have a track record of reliability. Also, skim the mailbox service agreement for any unusual clauses (e.g., some might require a notice period before cancellation to refund deposits, etc.).

Bottom Line: For many individuals, a USPS PO Box covers the essentials of privacy and security at lowest cost. It’s a great choice if you primarily need a secure mailbox for USPS mail and can live without a street address or carrier packages. If your needs are more complex - you run a small business, expect diverse package deliveries, or want the extra convenience of notifications and 24/7 access - a private mailbox is likely worth the extra expense. And if even more flexibility is needed (like managing mail from your phone or being able to be completely remote), a virtual mailbox service might be the best investment.

By considering the factors above and following the steps to rent your chosen box, you’ll soon have a secure new address for your mail. Enjoy the peace of mind that comes with knowing your mail and packages are held safely until you can pick them up!
