USPS Form 1583: Virtual Mailbox Guide

USPS Form 1583 authorizes a CMRA to receive mail on your behalf and is a standard part of opening many U.S. virtual mailboxes.

The practical answer

Expect identity verification and supporting documentation. Providers typically guide customers through their own onboarding workflow, and exact notarization or verification steps should be confirmed with the provider and current USPS requirements.

MailboxScout rule: verify the exact use case, not just the marketing label. “Real street address”, “business address” and “residential address” are not interchangeable terms.

What to compare before choosing a provider

  • Exact address and address classification
  • Incoming mail allowance and overage cost
  • Open-and-scan pricing and page limits
  • Forwarding handling plus carrier postage
  • Recipient and business-name limits
  • Storage rules and package fees
  • Whether the service you need is available at that exact location

Where to go next

Use our provider comparison for plan-level differences, then open the official provider page before signup to confirm current terms.

FAQ

Can I receive packages at a virtual mailbox?

Many providers can, but carrier support, package size rules, storage and forwarding fees vary.

Is a virtual mailbox a residential address?

Do not assume so. Many U.S. virtual mailbox addresses are commercial mail receiving addresses and may not satisfy institutions that require a residential address.
