Addressing Military & Diplomatic Mail
Each shipment to an APO/FPO/DPO needs the recipient's name, rank, and unit, and the APO/FPO/DPO address with the 9-digit 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. Here are properly addressed shipment examples:
Army/Air Post Office (APO)
PFC JOHN DOE
PSC 3 BOX 4120
APO AE 09021
Fleet Post Office (FPO)

Tips for Sending Military & Diplomatic MailExpand All
Properly Prepare Your Shipment
Whether shipping to domestic or overseas military and diplomatic Post Offices, make sure you follow the guidelines for preparing your box or envelope correctly so it arrives on time. Learn about size and weight requirements, calculating postage, and dropping off your shipment.
Tuck an Address Inside the Box
It's a good idea to include a second piece of paper with the address inside the box, just in case something happens to damage the label on the outside. Be sure to include both the destination address and your return address on the spare copy.
Keep Temperature in Mind
Remember that outdoor conditions can affect the contents of your package. Desert temperatures typically exceed 100 degrees, which can damage delicate goods like electronics.
