Virtual Mailbox & Form 1583 Rules in Michigan
A commercial mailbox rental (CMRA) or virtual mailbox in Michigan cannot serve as your LLC's registered agent address, though it may generally be used as a business address depending on your specific needs. When opening a virtual mailbox account, you'll need to complete a USPS Form 1583, which typically requires notarization. Michigan permits remote online notarization (RON) under its permanent notarial acts framework, and a notary may notarize a Form 1583 through RON, allowing you to complete the entire sign-up process online with an in-state notary.
Note that notarization requirements can vary by mailbox provider and USPS circumstances. This overview reflects current regulatory information, which changes periodically. Confirm the current requirements on Michigan's official state page and consult your mailbox provider directly before proceeding. This is not legal advice and does not substitute for guidance from an attorney or official regulatory sources.
How a virtual mailbox works
A virtual mailbox is a real street address at a commercial mail-receiving agency (CMRA) that scans your mail; opening one means filing USPS PS Form 1583, witnessed by a notary or the provider, with two IDs.

| Can a virtual mailbox be your registered agent? | No (a PMB cannot be your registered agent) |

Opening any virtual mailbox means filing USPS PS Form 1583. The form must be witnessed — by a notary or by the mailbox provider (the CMRA owner/manager), in person or by real-time audio-video under the 2024 CMRA Clarification rule — and you supply two acceptable IDs. It is usually notarized, and the notarization can be done online via remote online notarization (RON) wherever the state allows it.

Compiled from the USPS federal baseline (DMM 508 / 39 CFR) and the state notary/RON statute, and verified June 2026. Always confirm the current rule on the official state Secretary of State / notary page before you rely on it — RON law is still moving. This state's RON status is currently medium-confidence (the exact statute section is not yet pinned), so treat the online-notarization detail as a starting point and confirm it on the official page.
