What Are the Guidelines for Sending Military and Diplomatic Addresses?


You want to know how to format APO/FPO/DPO addresses.




  • When using APO/FPO/DPO addresses, make sure to follow the USPS guidelines, outlined here.
    • For example, the address:
      • SSGT Kevin Taylor
      • Unit 2050 Box 4190
      • APO AP 96278-2050 
    • Should be broken down as follows:
      • Address 1: Unit 2050 Box 4190
      • City: APO 
      • State: AP 
      • Country: US
      • ZIP: 96278-2050
  • If a military address is formatted as above and is still failing address validation, this may be due to the zip code not belonging to either the AP, AA or AE state value which is currently assigned to the address.
    • Military zip codes all belong to either the Armed Forces Pacific (AP), the  Armed Forces Europe (AE) or the Armed Forces America (AA) zip code list.
