GN 00904.025 Servicing Office For Military Addresses
All military addresses use a U.S. post office address even though they may represent installations in foreign countries.
For purposes of determining service office jurisdiction there are two types of military addresses:
A. Addresses without an APO or FPO designation
These are addresses on the U.S. mainland (excluding Alaska) and the servicing office is determined as with any U.S. address by accessing DOORS (Detailed Office/Organization Resource System)
B. Addresses with APO or FPO designation
Most APO/FPO addresses are foreign and are the jurisdiction of the Division of International Operations (DIO) (PSC 8).
Some APO/FPO addresses are under domestic PSC and servicing FO jurisdiction. These addresses are in the Caribbean (Puerto Rico and the Virgin Islands), the Pacific (Hawaii, Guam and American Samoa) and Alaska.
A list of APO/FPO zip codes and corresponding locations can be found on the Division of International Operations Home Page via the DIO REFERENCE LIBRARY -- APO and FPO CODES and LOCATIONS. http://ocoweb.ba.ssa.gov/oio/OIOResources/APO-FPO-Zip.asp
