How to Notarize Form 1583 for a Virtual Mailbox

Estimated read: 4 minutes · Virtual mailbox setup · Requirements

When you open a virtual mailbox, the provider typically asks for a notarized USPS Form 1583. This guide explains what most providers look for and how to avoid delays.

Why virtual mailbox providers require Form 1583

Form 1583 authorizes a commercial mail receiving agency (CMRA) to receive mail on your behalf. Providers often require notarization to confirm that the person signing the authorization is the same person shown on the ID.

How to fill Form 1583 without delays

Tip: If your provider gave you a preferred format (PDF vs image), follow it to avoid re-submission.

What to upload

Important: In the payment note, include Request ID + Email.

Provider notes that help

Many delays come from missing provider-specific instructions. If your provider requires something special (ink color, extra pages, or a specific CMRA address), include that in your submission notes so it can be reviewed during processing.
