Format your military address correctly

When adding or updating a U.S. military address as your shipping address, make sure it includes the correct information and formatting.

1. Use English characters only

Replace any non-English characters with the closest English equivalent. Special characters may prevent the address from being recognized.

2. Enter your full name

Include both a first and last name. Some carriers require both to process shipments.

3. Use the correct city, state, and country

Your address must include:

  • City: APO, FPO, or DPO
  • State: AP, AE, or AA
  • Country: United States
  • ZIP Code: Your assigned military ZIP code
  • Unit, box, or PSC numbers (and make sure they’re entered on the correct address line)

Example:

4. Double-check before placing your order

Confirm your address is saved correctly before placing your order.

Incorrect formatting may prevent checkout or result in shipping delays or cancellations

Tip: Review USPS military address guidelines to confirm your address will be accepted by their system.


For sellers shipping to APO/FPO/DPO addresses

U.S. military addresses are treated as domestic USPS shipments but must meet strict formatting requirements.

Before generating a label, confirm:

  • The city is APO, FPO, or DPO

  • The state is AP, AE, or AA

  • The country is United States

  • All unit, PSC, or box numbers are included

Some carriers require both the sender and recipient to have a first and last name (each with more than one character). If a name field contains only one word, you may not be able to generate a shipping label.

If the buyer’s address is formatted incorrectly, you may not be able to generate a label or complete the shipment.
