When addressing mail to a Military Post Office™ (MPO), do I need to include the city and country?

No. When addressing mail to an MPO, always omit the name of the city and country and use the APO or FPO address. This makes it more obvious that the mail is military mail when it enters the mail stream. 

Please see our guide on how to format military mail.

When shipping to an MPO, what is the difference between Parcel Post® and Priority Mail®?

Parcel Post® articles that are more than 15 pounds or measure more than 60 – length and girth combined will travel via ship from the U.S. gateway to the military address.

Priority Mail® articles usually travel via air transportation from the U.S. gateway to the military address overseas.

What extra services are available for Military mail?

Generally, services such as the following are available to MPOs.

  • Insured Mail
  • Registered Mail (Not currently available with ShippingEasy)

You can track a package to an APO/FPO address if you purchase the applicable extra service. Although your article may include a customs form, you cannot track it via the customs declaration numbers as they are only used to track international mail articles.

Are there any special tips or precautions I should take when packaging military mail?

From the  Military Postal Service Agency:

  • Place the mailing address inside the parcel on a separate piece of paper.
  • Use a box that is constructed to conform to the contents you are sending.
  • Place items in the box so that the weight is evenly distributed.
  • Add packing material on the inside if any portion of the box sags or is easily depressed.
  • Use packaging tape for wrapping the outside of the box. Do not wrap with string.
  • Cross out or cover excess markings or printing to prevent your box from being missent.
  • Enclose all personal hygiene items, such as deodorant, lotion, or shampoo, in a sealable bag.
  • Place all perishable items, such as cookies, chips, etc., in a plastic container.
  • When mailing liquids, ensure they are properly packaged. Limit the quantity, use a leak-proof container, and wrap the articles in an absorbent material between the inner and outer containers.
