Virtual Mailbox & Form 1583 Rules in Utah
A commercial mailbox or virtual mailbox service in Utah cannot serve as your LLC's registered agent for official state filings, though it may generally be used as a business address depending on the provider's policies. When opening a virtual mailbox account with the U.S. Postal Service, you will typically need to complete a PS Form 1583. This form usually requires notarization, though the USPS may accept attestation by the mailbox provider's owner as an alternative in some cases. Utah permits remote online notarization (RON) under its Online Notarization Act, effective since 2019, which means you can have your Form 1583 notarized by a Utah notary online without visiting in person.
However, notarization rules and CMRA policies can change. Before opening a virtual mailbox, confirm the current requirements directly on the official Utah state notary page and contact your chosen provider about their specific witnessing and notarization procedures. This overview is regulatory information only and not legal advice. Consult a licensed attorney in Utah for guidance on your particular business setup.
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.

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.
