Completing USPS Form 1583 for Identity Verification

Why Form 1583 is required and how to complete identity verification for your mailbox.

USPS Form 1583 authorizes Anytime Mailbox to receive mail on your behalf and is required by federal regulation for every private mailbox holder.

To complete verification you will need:

  • One government-issued photo ID (passport, driver license, or state ID).
  • One secondary form of ID, such as a utility bill, vehicle registration, or insurance card.

The form is notarized electronically during signup -- no need to visit a notary in person. Verification typically completes within one business day.
