Fill out PS Form 1093 Online in 2026

Form PS 1093, Application for Post Office Box Service, is a U.S. Postal Service document used by customers to apply for a new post office box, update an existing one, or change box service options. Individuals, families, and small businesses fill it out at a local post office to give USPS the names, addresses, and identification details needed to issue keys, set the rental term, and authorize who may receive mail at the box.

PS 1093 puts the details USPS needs to set up or update a post office box rental into a single signed application. Customers use it to:

• Apply for a new post office box at a chosen post office
• Add or remove names authorized to receive mail at the box
• Update home address, phone, or identification on file
• Switch between standard and Group E business rental terms

1. Enter the name and physical address of the person or business renting the box.

2. Add the date of birth, phone, and email so USPS can reach you.

3. List every adult and minor authorized to receive mail at the post office box.

4. Choose the box size and rental term offered at the post office.

5. Provide two acceptable forms of identification, with at least one valid photo ID.

6. Review every required field for accuracy before sharing the completed form.

Anyone who wants to rent a post office box from the U.S. Postal Service completes PS 1093, including individual residents, families sharing one box, sole proprietors, and small businesses. The customer of record signs the application, lists every other authorized recipient, and shows valid identification at the post office where the box is housed.

After the form is signed, USPS staff verify the identification, log the customer into the post office box system, issue keys or a combination, and start the rental term. Carriers and box clerks use the application to confirm who may receive mail at the box throughout the rental.

Customers who do not need a post office box do not file PS 1093. People who already rent a current box and have no changes to identification, authorized names, or contact details simply renew through the rental notice instead. Private mailbox services from companies other than USPS use their own paperwork and identification rules under the Postal Service's Form 1583 instead of PS 1093.

The deadline for PS 1093 is whenever you want a new post office box, an update to an existing rental, or a change in authorized names. New boxes typically become active the same day the application is signed and the rental term is paid. Renewals follow the rental cycle printed on the post office box payment notice, and USPS may close a box for nonpayment after a short grace period.

The U.S. Postal Service issues PS 1093 at every local post office that offers post office box service and on the official USPS website. Prefer to fill in your details before heading to the counter? Our editor has a blank ready — download the completed copy, bring it with your two forms of ID, and the clerk takes it from there.

PS 1093 must be signed by hand in ink at the post office where the box is housed, since USPS staff verify the customer's identification at the same time the wet signature is captured. After you fill the form on our platform, download the completed file, print it, and bring it to the retail counter for the ink signature, dates, and verification. Checking the latest USPS guidance is a good idea before your visit.

Once your PS 1093 is signed at the counter, hand the original to the retail clerk at the post office that will house the post office box. USPS keeps the application on file for the rental and uses it whenever staff need to confirm authorized recipients or update box service. Some smaller offices ask customers to drop the form at the lobby box service desk.
