Question: how to fpo addresses work?
Answer: Military addresses must show the grade, full name with middle name or initial, and PSC number, unit number, or ship name. Replace the city name with "APO " or "FPO," and the state with "AA," "AE," or "AP," and use a special ZIP Code. All APO / FPO shipments must be made by using the United States Post Office (USPS).
