USPS Form 1583 Notarization: The complete Massachusetts guide.

Pre-Signing the Form

The signer fills out the form at home, signs it, then brings it to the notary. The notary cannot acknowledge a pre-signed form. The whole form must be voided and a fresh one signed in front of the notary.

Missing Second ID

One photo ID is not enough. The form explicitly requires two forms of identification. Bring both to the appointment. The notary records the ID information including the type, issuing agency, number and expiration date in the journal.

Name Mismatch

The applicant writes a casual version of their name. The ID shows the legal full name. The CMRA rejects forms where the names do not match. Always confirm legal name spelling at the time of signing.

Wrong Address

The applicant writes a current home address but the photo ID shows an old address. Bring updated address documents to verify current residence. Utility bills, vehicle registration or signed lease all work.

Outdated Form Version

USPS occasionally updates Form 1583. Use the version your CMRA sent you, not a downloaded copy that may be outdated. Old form versions get rejected at the USPS approval stage.

USPS uses Form 1583 to confirm the identity of every individual or business operating a private mailbox. Without a properly notarized form, the CMRA can be fined, lose its USPS authorization and have its mail forwarding privileges revoked. Customers can lose access to their mail with no notice.

The notary’s role is to verify identity and witness the signature. The CMRA’s role is to file the form with USPS. Together they create the chain of custody that prevents mail fraud.

Common Use Cases

Small business owners running an LLC from home who do not want their home address on public filings. Professionals registering a business with the Secretary of the Commonwealth who need a separate registered agent address. Real estate investors managing property from a different state. Online entrepreneurs receiving inventory or returns at a CMRA. Travelers who spend extended periods away from home.

The in-person path is the simple one. Bring the completed, unsigned form and your identification to our office at 1215 Main St in Tewksbury, weekdays 10 to 5 by appointment, free parking at the door. The ID check happens across the table, the signature goes on in front of the notary, the certificate and seal complete the set, and the whole visit runs minutes. In-office notarization is $45 per notarial act or signature. One applicant is $45; a couple applying together is $90. If leaving the house is the obstacle, mobile service comes to you at flat zone rates with 2 seals included, $125 within 5 miles of our office, $199 within 10 and $278 within 40, though for this particular form a solo applicant is almost always better served by the office visit, and we say so when asked.

The online path fits the virtual mailbox crowd naturally, since the entire relationship is digital anyway. Many virtual mailbox providers accept remotely notarized 1583s and some even embed a RON session in their signup flow. Acceptance is the provider’s call, so confirm before booking either path. Our online notarization page explains how sessions work, and our online versus in-person comparison helps you weigh the tradeoffs honestly. A traveler in Arizona applying for a Massachusetts virtual mailbox should not drive to Tewksbury, and we would be the first to tell them.

Households mixing the paths is normal, for the record. A common combination: the primary applicant handles an in-person signing during an errand run while a spouse traveling for work completes their portion by RON two days later, and the provider assembles the pair. Nothing requires all applicants on one mailbox to notarize the same way or the same day. What the provider wants is a complete, internally consistent set, and consistency is a checklist problem, not a scheduling one.

Whichever path you choose, the identification rules deserve respect because this form carries a two-ID requirement that surprises people. One photo ID and one additional ID from the form’s accepted lists, with addresses that hold together across the paperwork. The photo ID does the identity work at the notary table; the full set does the compliance work at the CMRA. Our guide to ID requirements for notarization covers the notary side, and your provider’s checklist covers theirs. Bring more documentation than you think you need. Nobody has ever regretted the extra card in the wallet.

Renewals and changes bring the form back around more often than people expect. Adding a spouse to the mailbox, converting a personal box to a business one, changing the business entity behind the box or moving to a new provider each typically triggers a fresh 1583, and providers periodically re-verify long-standing customers. The second pass goes faster than the first because you know the drill, but it still needs the same care: current IDs, matching names and an unsigned form at the table. Keep a scan of each completed 1583 with your provider paperwork, since the old form answers most questions the new one raises.

Businesses scaling past one mailbox meet the form again at volume. A company giving each field rep a mail anchor, a franchise standardizing addresses across territories or an agency managing mail for multiple client entities generates a stack of 1583s, each needing its own authorized signature and notarization. Batch sessions handle these cleanly, either at our office or as a mobile visit to yours, with the per-signature math scaling predictably instead of surprising anyone at invoice time.

One caution earned from experience: do not improvise fixes on a completed form at the notary table. A crossed-out address or an overwritten box number invites the provider’s compliance desk to reject the whole submission, and the notarization goes down with it. When a field is wrong, reprint the form, re-enter the data and sign the clean copy. Paper is cheap. A bounced application that resets the provider’s queue is not.

Timing runs in your favor. There is no government backlog here: the form is effective as soon as the provider accepts it, so the notarization is usually the same week you decide to get a mailbox, and same-day service covers the rare 1583 emergency with a $25 surcharge inside 4 hours notice. The complete rate table lives on the notary pricing page. When the form is filled and the IDs are gathered, book your appointment or call 978-424-4629, and your new address goes live without the form bouncing once. Payment takes credit, debit, Apple Pay, PayPal, Zelle or cash, and the quote you hear when booking is the total you pay at the table.
