Who needs to file PS 1093?
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.
Who doesn't need to file PS 1093?
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.
When is PS 1093 due?
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.
