Mailboxes FAQ

5. Should I send the Form 1583 to my post office?

No, you should not send USPS Form 1583 to your local post office. Instead, Form 1583 should be submitted directly to the Commercial Mail Receiving Agency (CMRA) where you are renting a private mailbox or using a virtual mailbox service. The CMRA will handle the verification process and submit the necessary documentation to the USPS on your behalf.
