Verifying Your Identity (USPS 1583 Form)

Many users wonder why the USPS 1583 form is required, or why it asks for two different types of identification. This article will explain everything.

It's a Critical Security Step to Verify Your Identity, and Protect Your Privacy

This step is essential because:

  • The U.S. Postal Service requires all Commercial Mail Receiving Agents (CMRA) to collect this information.
  • It ensures that you, and only you, are able to access mail that is addressed to you. 

The Postal Consent Form (USPS Form 1583) legally allows Earth Class Mail to receive mail on your behalf, and gives you unrestricted access to that mail.

Understanding the Postal Consent Form (HINT: It's NOT a change of address)

The 1583 Form authorizes us to accept mail in your name, it does not change your address with the USPS or tell us where to forward your mail.

To get mail directed to your Earth Class Mail address, you'll need to notify senders of your new address, or file a Change of Address with the U.S. Postal Service.



The 1583 form must be signed and notarized, and sent along with the acceptable forms of identification.

If you hold multiple Earth Class Mail addresses only your first Postal Consent Form must be notarized. Once we have received a notarized USPS Form 1583 and verified your identity the others for your additional addresses can be completed and sent to us without notarization.
