The Postal Service operates as an extension of the U.S. Postal Service to bring authorized members of the Area IV community the most expeditious and efficient, personal and official mail services possible; comparable to that enjoyed domestically.
How to address mail:
Army/Air Post Office (APO)
PFC JOHN DOE
PSC 3 BOX 4120
APO, AP 96XXX
Each shipment to an APO/FPO/DPO needs the recipient's name, rank, and unit, and the APO/FPO/DPO address with the ZIP Code™. Always include a return address. Mail and shipments must be addressed to a specific person; addressing to "Any Service Member" is no longer permitted. To prevent mail from entering foreign mail networks, do not include city or country names in APO/FPO/DPO shipping addresses.
