Army Post Office ZIP Codes
Army Post Office, APO, is used for addressing mail to U.S. Army and Air Force installations, including those located overseas. This system allows military personnel and their families to send and receive mail as if they were in the United States, helping maintain a sense of normalcy and connection with home.
When addressing a package or letter to an APO address, you’ll use the recipient’s name, unit, and APO location, followed by a regional designation such as AE (for Europe, the Middle East, Africa, and Canada), AP (for the Pacific), or AA (for the Americas and South America).
The U.S. Postal Service treats APO mail as domestic mail, despite it often traveling internationally, offering a cost-effective way for families to keep in touch with service members abroad.
