Shipping via Military Mail Tips

 (APO, FPO, DPO)

If you are shipping to a military base or diplomatic location, you'll be using an APO, FPO or DPO address. 

  • APO stands for Army Post Office and is associated with Army or Air Force installations.
  • FPO stands for Fleet Post Office and is associated with Navy installations and ships.
  • DPO stands for Diplomatic Post Office and is associated with U.S. Diplomatic locations.

 

How do I format a military address?

There are seven main components to a valid APO, FPO or DPO address.

1. The name of the recipient. The rank/grade/rating is not required.

2. The type of address where the mail is going. This could include:

  • PSC (Postal Service Center)
  • CMR (Community Mail Room)
  • UMR (Unit Mail Room) or just Unit
  • RPO (Regional Post Office)
  • APO (Army Post Office)
  • OMDC (Official Mail Distribution Center)
  • For Navy or Coast Guard vessels, the ship’s name and hull number.

3. The number of that address. For example:

  • PSC 1234
  • Unit 7400
  • USS Nimitz (CVN 68)

4. The recipient's Military PO box number (if they have one).

5. The post office type (APO, FPO or DPO)

6. The "state" designator (either AA, AP or AE). These "states" represent the USPS mail processing facilities that handle the mail traffic to and from each military location.

7. The zip code, preferably ZIP + 4 (although not required)

That’s it! Here are some sample addresses that are formatted correctly for each post office type:
