You may download a pre-populated USPS 1583 Form by logging in to your Anytime Mailbox account on either a computer or a laptop.
Then, click the blue button ‘’Complete Renter Verification.’’
You will then be routed to another page where you will download the form. Since its pre-populated, all you need to do next is to have it notarized.
Unfortunately, this option isn’t available on the mobile app.
