Addressing Military Mail – APO – DPO – FPO


What is an APO, DPO, or an FPO 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.

Military addresses must show the grade, full name with middle name or initial, PSC number, unit number, or ship name. Replace the city name with APO, DPO, or FPO and the state with AA, AE, or AP, and use a special ZIP Code.

It is not necessary to add the specific military formation (for instance 1/20 24th Infantry) that the recipient is attached to.

All packages must have completed Customs Forms attached if being sent to a soldier in a foreign country.

To properly address a military mailpiece, you will need the following information:

  1. Name of the recipient (rank/grade/rating is optional).
  2. The PSC (Postal Service Center), CMR (Community Mail Room), UMR (Unit Mail Room), RPO (Regional Post Office), APO (Army Post Office) or OMDC (Official Mail Distribution Center) number.
  3. For FPO addresses aboard a United States Navy or a United States Coast Guard vessel, put the ship’s name and hull number, instead of a PSC number.
  4. The recipient’s Military Post Office Box number.
  5. The APO and “state” designator (AA, AP, AE). Do not use the state that the distribution hub is in (FL, CA, NY). This may cause delays in your package being processed.
  6. The ZIP Code for the unit, preferably the ZIP+4.

When mailing to a DPO address, do not add the street address of the embassy or the recipient’s job title.
