How to Properly Format a P.O. Box Mailing Address

When addressing mail to a P.O. Box, it is crucial to follow the correct format to ensure your mail reaches its intended recipient. Here are the steps to properly format a P.O. Box as a mailing address:

Proper Format for P.O. Box

Start with the recipient's full name on the first line. Include the company or organization name if applicable on the next line. Specify the city, state, and zip code associated with the P.O. Box on the last line.

Here is an example of the correct format for a P.O. Box mailing address:

John Smith
ABC Company
P.O. Box 123456
City, State Zip Code

Remember to write legibly, include a return address, and affix the proper postage amount to ensure smooth delivery of your mail.

Additional Tips for Addressing P.O. Boxes

Here are a few more tips to keep in mind:

For residential mailboxes, you would write: Name of the sender on the right side Then write the P.O. Box number on the right side Leave a space then write the city or town and date Write the recipient's name and P.O. Box on the right side

For addressing a mailbox, you should include the following information:

The recipient's name The name of the business or organization if applicable The address of the recipient The city, state, and PIN code

Correct USPS Format

The correct format for a P.O. Box should be:

Recipient’s Name
P.O. Box XXX
City State Zip 4

Never add the recipient's physical address to this format. It is strictly ONE or the OTHER and NEVER both! Always use the P.O. Box address provided to you, as that is the preferred and legally mandated address format for P.O. boxes.
