The U.S. Military Postal Service (MPS) works with the United States Postal Service (USPS) to deliver military mail worldwide.
Most USPS special services are available for MPS mail. Postage rates are typically equivalent to U.S. domestic postage rates. Shipments to these addresses should only require postage for reaching their destination within the United States.
The abbreviations APO (Army Post Office or Air Force Post Office) and FPO (Fleet Post Office: Navy or Marine Corps) are used as the city abbreviations for military mail. APOs and FPOs do have some special mailing requirements and restrictions. For more information, please review USPS guidelines, including Military Addressing Tips.Shipping setting defaults, options, and the ability to set exceptions, vary by seller account type and product type. For more information search on "shipping settings" in seller Help.
