Virtual Mailbox & Form 1583 Rules in Texas
A commercial mailbox rental (CMRA) or private mailbox (PMB) in Texas cannot serve as your LLC's registered agent address with the state, though it may generally be used as a business address for other purposes. This is a uniform restriction across virtual mailbox providers in Texas.
When opening a virtual mailbox account, the USPS Form 1583 typically requires notarization, though the USPS may accept either a notary's certification or the mailbox provider's owner witnessing. Texas allows remote online notarization (RON) under its permanent RON rules in effect since July 2018, and a Texas-licensed notary may notarize Form 1583 online, enabling residents to complete the entire signup process remotely. However, notarization rules and regulatory requirements change; confirm current procedures on the official Texas Secretary of State and USPS websites before proceeding.

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.
| Detail | As the rule stands |
|---|---|
| Can a virtual mailbox be your registered agent? | No (a PMB cannot be your registered agent) |
| Can it be your LLC business address? | Generally yes — verify |
| Online notarization (RON) for Form 1583 | Online notarization (RON) available |
| Form 1583 witnessing | Notary or CMRA-owner witness (in person or by A/V) |
| PMB designator (address line) | 'PMB <number>' or '# <number>' (USPS DMM 508.1.4) |
| Governing citation | Tex. Gov't Code §406.101 et seq.; USPS DMM 508.1.8 |
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.
