Just signed up for a private mail box (PMB). I had to fill out USPS form 1583 to make this happen. I received a hardcopy of that form while at the mailbox company, and they apparently keep another copy and mail a third copy to the USPS.
Question: Will the USPS be sending a copy of that filled-out form to my home address? I can’t think of a reason they would - the mailbox company made me show two forms of photo ID before I could sign up - but I wonder just the same.
