What is APO shipping?

  • APO stands for the Army Post Office.
  • This is the organization that handles the shipping and delivery of mail for members of the US Army or Air Force.
  • The APO manages the mail of force members based in the U.S (domestic delivery) and those deployed overseas.

DPO, and FPO

Alongside the APO there is the FPO (Fleet Post Office) for the Navy and the DPO (Diplomatic Post Office) for US diplomats. These are the three main military post offices.

FPO (Fleet Post Office)

The FPO manages the delivery of packages for the Navy. The fact Navy members are stationed on ships around the world makes the logistics of this more complicated than other military post offices.

Very often, FPO packages take the longest to arrive.

DPO (Diplomatic Post Office)

The DPO is in charge of delivering packages for US diplomats.

This includes a long list of personnel that can be stationed in embassies and other institutions around the world.

Ambassadors and all necessary diplomatic staff (administrators, translators, etc) will receive and send mail via the DPO.

How to Send APO/FPO/DPO Military Mail

APO Shipping Military Mail is how you can send mail items to members of the armed forces.

The APO handles both letters and packages. Interestingly, even where the final destination for the mail item is abroad, the APO handles all mail as domestic in terms of rates.

Military Mail Address Format

When addressing mail for APO shipping you should adhere to the following format.

1. Name of the recipient

As with any normal mail item the recipient’s name goes at the top. It is important that you use the full legal name that the military will have on file.

2. Unit or type of address

You will then need to put the unit code for the type of address the mail is being sent to. The list is as follows. If you don’t know this, you will have to contact the recipient to find out.

  • PSC (Postal Service Center),
  • CMR (Community Mail Room),
  • UMR (Unit Mail Room),
  • RPO (Regional Post Office),
  • APO (Army Post Office)
  • OMDC (Official Mail Distribution Center) number.

4. State Designator

Next, you have to add the state designator of the APO.

  • AE is used for armed forces in Europe, the Middle East, Africa, and Canada.
  • AP is for the Pacific.
  • AA is the Americas, excluding Canada.

You may also have information on the state-based distribution hub. There is no need to add this as part of the designator.

5. The Full Address

Now you can add the rest of the address details that you have for the APO shipment. This is normally in the form of a Zipcode.

Notes for FPO & DPO Shipments


FPO & DPO shipments follow a similar format, however, there are some differences to be aware of.

For FPO addresses aboard a United States Navy or United States Coast Guard vessel, you should add the ship’s name and hull number as the main part of the address, (step 5 above).

When mailing to a DPO address, there is no need to add the street address of the embassy. You should not add the recipient’s job title either.

Which carriers send to military addresses?

There is only one carrier that can deliver packages to APO addresses and that is USPS. This is because USPS is the only entity that has governmental permission to do so. Security concerns are the overriding factor in this.

FedEx and UPS can send packages to other countries where military forces are concentrated, however, these will not go through the APO shipping process. The recipient would have to collect from the local hub of the relevant carrier or organize some other means of collection.

Final Words

Sending packages via APO shipping is not difficult. By following the simple formatting rules of the relevant military post office, (APO, FPO, or DPO) your mail item will arrive at its destination without error.

It is a good idea to confirm the details with the recipient before sending the item, however. Enter the address incorrectly and there can be a period of delay before the item is delivered.
