A Complete Guide to Shipping to APO/FPO Addresses in 2025

Introduction

Shipping packages or letters to U.S. military personnel stationed around the world is a meaningful way to show support. However, sending mail to APO (Army Post Office) and FPO (Fleet Post Office) addresses requires specific formatting and procedures to ensure delivery. This guide simplifies the process, providing essential tips and best practices for shipping to APO/FPO addresses efficiently.

What Are APO and FPO Addresses?

APO and FPO addresses are specialized mailing addresses used by the U.S. military for delivering mail to personnel at bases, ships, and installations worldwide. Unlike standard addresses, these require adherence to specific guidelines. Understanding and correctly formatting these addresses ensures smooth delivery.

Step-by-Step Guide to Addressing APO/FPO Mail

Step 1: Write the Full Name and Rank

Always include the service member’s full name and rank. For example:

• Correct: "CDR Bob Smith" or "CDR Smith, Bob"

Step 2: Include the Ship or Unit Name

Add the ship or unit name in the company line to assist with routing. For example:

• "USS John Paul Jones"

• "HSC-13"

Step 3: Include Unit and Box Number

Specify the assigned unit and box number:

• Example: "Unit 100535 Box 3333"

If uncertain, use a default like "Box 1."

Step 4: Use "APO" or "FPO" as the City

Replace the city name with "APO" (Army Post Office) or "FPO" (Fleet Post Office). This indicates a military destination.

Step 5: Use Military Postal Abbreviations

Instead of a state, use one of the following abbreviations:

• AE: Armed Forces Europe, Middle East, and Canada

• AP: Armed Forces Pacific

• AA: Armed Forces Americas (excluding Canada)

Step 6: Provide the ZIP+4 Code

While not mandatory, including the ZIP+4 code enhances sorting accuracy and speeds up delivery. If unknown, the five-digit ZIP code is sufficient but may result in slightly slower delivery times.

Example Address Format:

PO1 John Doe

USS John Paul Jones

Unit 100535 Box 3333

Deck Division (optional)

FPO, AP 96667-1234

Customs Forms for APO/FPO Mail

When sending packages, complete the required customs forms:

• Use PS Form 2976-A to declare the contents, weight, and value of the package.

• Provide detailed descriptions of the items (e.g., “3 pairs of socks, 2 books”).

• Sign and date the form accurately.

If using a third-party service, such as Fleet Sheets, they may handle customs forms for you.

Carriers That Ship to APO/FPO Addresses

Only the United States Postal Service (USPS) delivers directly to APO/FPO locations. Private carriers like FedEx and UPS cannot deliver directly due to military restrictions but may forward packages to USPS for final delivery.

Recommended USPS Services:

• Priority Mail: Faster delivery option.

• Parcel Select: Affordable but slower.

Delivery Times for Military Mail

Delivery times vary depending on location and circumstances. Packages may take anywhere from 3 to 45 business days to arrive. Factors influencing delivery include:

• Military Operations: Availability of transportation like aircraft or ships.

• Weather Conditions: Adverse weather may delay shipments.

• Destination Proximity: Remote or overseas locations require more time.

• Sorting Delays: Delays within the military postal system can occur.

Conclusion

Shipping to APO/FPO addresses doesn’t have to be complicated. By adhering to proper addressing formats, completing customs forms accurately, and using USPS services, you can ensure your packages reach their destination smoothly. Whether it’s a letter or a care package, following these steps ensures your support for U.S. military personnel is felt no matter where they’re stationed.
