Services at Superior Post Office

Street parking. Here's what you can do at this location:

Shipping

Label Broker
For online sellers: give your customers a Label Broker ID or QR code so they can print a prepaid USPS return label at this post office — no printer needed.
Priority Mail International
Affordable international shipping with delivery in 6–10 business days to most countries. Includes tracking and insurance up to $200.

PO Box & Mail

General Delivery
Receive mail without a permanent address. Mail is held at the post office and you pick it up at the counter with a valid ID. Often used by travelers or people between moves.
Accountable Mail Pickup
Pick up items that require a signature: Certified Mail, Registered Mail, Collect on Delivery, insured packages, and Signature Confirmation items.
Hold Mail Pickup
Pick up mail that USPS has been holding while you were away. You can request a hold for up to 30 days through usps.com or at the counter.
Package Pickup (Notice Left)
Pick up a package that couldn't be delivered — the carrier left a slip at your door. Bring the notice and a valid ID.
PO Box (Online Management)
Rent a PO Box and manage billing online. A PO Box gives you a secure, private mailing address — useful if you run a business or want to separate personal and business mail.

Domestic Money Orders
Purchase money orders up to $1,000 each — a secure way to send payments without a bank account. Accepted nearly everywhere and traceable if lost.
Money Order Inquiries
If a money order is missing, lost, or stolen, you can file an inquiry here. Bring your receipt — USPS can trace and replace it.
