Services at Martinsville Post Office

Shipping
- Carrier Services

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.

- 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.
