Why is USPS Form 1583 required?

Any person or business renting a mailbox directly from an approved third party (CMRA) must complete the USPS Form 1583 to authorize the CMRA to handle their mail. When submitted to the United States Post Office, Form 1583 will be stored and kept on file to identify and track addressees using this service for any unapproved or illegal purpose.
