A Step-by-Step Guide to Completing USPS form 1583, digital mailbox

If you’re signing up for a virtual address, you’ll almost certainly run into one required form: USPS form 1583, digital mailbox. This short guide explains what the form is, why it matters, and exactly how to complete it so your virtual mailbox setup moves smoothly. No jargon—just the practical steps you need to get your mail flowing to a secure business address.

What is USPS Form 1583 and why it matters

USPS Form 1583 authorizes a third party (like a virtual mailbox provider) to receive mail on your behalf. Think of it as a legal permission slip: the USPS needs to confirm your identity and approve the mailbox operator who will handle your mail. Without a completed and notarized form, your provider can’t accept mail for you.

Who needs this form?

• Anyone registering a virtual mailbox or mail forwarding service.
• Small businesses that want a professional business address.
• Remote workers, entrepreneurs, or anyone who needs secure mail handling while away from a physical office.

What you’ll need before you start

1. Complete contact details: your full name, company name (if applicable), physical address, and phone/email.
2. Two forms of ID:
   • Primary (photo) ID: state-issued driver’s license or passport.
   • Secondary ID: current lease, mortgage statement, vehicle registration, or similar document.
   • Important: you cannot use the same document as both primary and secondary ID.
3. Notarization: the completed form must be notarized. You can use an online notarization service (if offered by your provider) or visit a local notary at a bank, CPA, or shipping center.

Step-by-step: Filling out form 1583

1. Download the form or get it from your virtual mailbox provider.
2. Fill in your full legal name and any business name exactly as they appear on your ID and registration documents.
3. Enter your physical home address (not the virtual mailbox address) and contact information.
4. List the names of any individuals authorized to receive your mail through the virtual mailbox.
5. Attach copies of your two IDs—one primary with a photo and one secondary without a photo is acceptable.
6. Sign the form in front of a notary. If you use an online notary offered by your provider, follow their verification steps.
7. Return the notarized form and ID copies to your virtual mailbox provider for final processing.

Tips to avoid delays

• Make sure names and addresses match exactly across the form and IDs.
• Use clear, legible copies of your documents—scanned PDFs are best.
• Don’t try to use the same document as both primary and secondary ID.
• If your form needs notarization, schedule it early—bank and shipping center notaries can have limited hours.
• Ask your provider if they offer online notarization; it can save time and a trip out.

FAQ

Can I use a passport and a bank statement as my two IDs?

Yes. A passport is an acceptable primary photo ID. A recent bank statement can serve as a secondary ID as long as it includes your current address and matches the name on the form.

What if I’m not a U.S. citizen?

Non-U.S. citizens can usually complete form 1583, but acceptable IDs vary. A passport plus a secondary proof of address (like a lease or utility bill) is commonly accepted. Check with your virtual mailbox provider for any additional requirements.

Can I sign the form remotely?

Only if your virtual mailbox provider supports online notarization. The form must be notarized—either in person or via an accredited online notary service.

How long does approval take?

Processing times vary by provider. If all documents are correct and notarization is complete, approval is often quick—sometimes within 24–48 hours.

How do I change authorized recipients later?

Contact your virtual mailbox provider. They’ll often require a new, signed and notarized form 1583 listing the new authorized recipients.
