USPS Form 1583 Explained — The Key to Secure Virtual Mailboxes and Authorized Mail Handling

USPS Form 1583, formally named Application for Mail Delivery via Authorized Agent, is a mandatory identity-verified document from the U.S. Postal Service that allows someone to appoint a Commercial Mail Receiving Agency (CMRA) to receive correspondence in their name. Businesses like Anytime Mailbox and other providers such as PostScan Mail, Postbox Inc., and iPostal1 all rely on this form before a mailbox can be activated or mail can be stored on someone’s behalf.

Without a notarized Form 1583 on file, a CMRA is not permitted to hold, forward, or safeguard your mail — this protects clients by creating verified authorization records and blocking unauthorized access, fraudulent mailbox claims, or mail fraud.
