If you’re planning to sign up with a Commercial Mail Receiving Agency (CMRA) to receive mail and packages from the United States Postal Service (USPS), you’ll need to complete a USPS Form 1583. This form is a critical step in authorizing the CMRA to manage your mail, ensuring everything is done legally and securely. Here’s a quick guide to help you understand what it is and why it’s necessary.


The USPS Form 1583 is a legal document required by the USPS whenever you want to use a CMRA, like the UPS, iPostal1, or Traveling Mailbox, to handle your mail. It’s essentially your formal authorization, giving the CMRA permission to accept, store, and manage USPS mail on your behalf.
