How to Notarize Form 1583 for a Virtual Mailbox
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
- Use the same legal name across the form and your ID.
- Double-check your address fields (typos can trigger re-checks).
- Follow your provider’s signing instructions (some want you to sign during the session).
What to upload
- USPS Form 1583 (PDF preferred)
- Photo ID (clear scan/photo, all edges visible)
- Your email for receiving the notarized PDF
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.
