What is USPS Form 1583?
USPS Form 1583 — Application for Delivery of Mail Through Agent — is the document that authorizes a Commercial Mail Receiving Agency (CMRA) such as The UPS Store, PostalAnnex, or a private mailbox service to accept and hold mail on your behalf.
Anyone who rents a mailbox at a CMRA must complete Form 1583. This includes:
- Small business owners using a business address service
- Travelers, digital nomads, and people who relocate frequently
- People who prefer not to use their home address for business correspondence
- Anyone setting up mail forwarding through a private service
Why Notarization Is Required
The USPS mandates notarization of Form 1583 to verify identity and prevent mail fraud. Federal regulations under 39 CFR Part 111 require that the CMRA keep a notarized copy of the form on file. Without it, the CMRA cannot legally accept your mail.
The notarization requirement applies to all applicants — individuals and businesses alike.

- Download your notarized document. You receive a digitally sealed PDF that the CMRA will accept.
Submitting the Completed Form
Once notarized, bring or send the completed Form 1583 to your CMRA along with two forms of identification:
- ID 1: A valid, current driver's license or passport (primary identification)
- ID 2: Any second form of ID (credit card, vehicle registration, utility bill)
The CMRA will keep the notarized form on file. You do not need to submit it to USPS directly.
