How to Properly Address a PO Box

When sending mail to a post office box (PO Box), remember to include the recipient's name, company (if applicable), and the unique PO Box number, along with the city, state, and zip code. Ensure your address format adheres to postal service guidelines for accurate delivery.

Ensure the delivery address is prominently placed in the center of the envelope to facilitate sorting and prevent mishandling due to unclear or incorrect labeling.

Ensure the recipient's full name is clearly written, including any middle initials or formal titles, to avoid confusion and ensure accurate delivery.

Include the name of the company or organization after the individual's name when applicable, without additional details like job titles.

Specify the PO Box number without punctuation, starting with 'PO Box,' followed by the assigned number, and note the differences in addressing PO Boxes internationally.

Provide the city, state, and postal code in the correct format, separating them with commas, and include the country name for international addresses.

Ensure you can find unknown PO Box numbers through online searches or product packaging, and accurately copy the address for mailing purposes.

Write your address legibly, considering that someone else will need to read it quickly. Printing is preferred over cursive, and using all capital letters may enhance clarity.

Include a return address on your mail, positioned correctly to avoid confusion with the delivery address.

Attach the appropriate postage securely to cover delivery costs, and ensure it doesn't obscure any address details.

Double-check for errors in your letter before sending, paying particular attention to numerical details to prevent misdelivery.

Use a dark-colored pen or permanent marker to write the recipient's address, avoiding pencils for clarity.
