How it works

1. Upload your USPS Form 1583

Download your pre-populated USPS Form 1583 from your Anytime Mailbox dashboard and upload it to Proof. You may contact Anytime Mailbox support for assistance.

2. Provide proof of identity

Proof will ask you to upload two acceptable forms of ID for identity verification and to validate the address on your USPS Form 1583.

3. Connect with a live notary

In seconds, Proof will connect you with a commissioned notary over a live video feed. The notary will confirm your identity, witness your signature, and assist you throughout the process.

4. Submit your documents

After the notary meeting, Proof will prompt for credit card payment before you can access your completed forms. You must then log into your Anytime Mailbox dashboard and upload the form together with your two IDs.

Contact Anytime Mailbox support if you need any help. Note that you need to complete this step in order to fully verify your Anytime Mailbox account.
