Virtual Mailbox & Form 1583 Rules in Arizona
A commercial mail receiving agency (CMRA) or private mailbox (PMB) in Arizona cannot serve as your LLC's registered agent address, though it may generally be acceptable as a business address (verify current requirements with the Arizona Corporation Commission). When opening a virtual mailbox with the U.S. Postal Service, you must complete Form 1583, which typically requires notarization or witnessing by the CMRA owner; however, notarization is not universally mandatory across all scenarios. Arizona permits remote online notarization (RON) under its permanent RON framework, and Arizona notaries may notarize Form 1583 through RON, allowing residents to complete the entire virtual mailbox setup online.
Because regulations change and specific requirements depend on your particular situation and the CMRA provider's policies, you should confirm current rules directly on the official Arizona Corporation Commission website and the USPS Form 1583 instructions. This overview is factual information only and does not constitute legal advice; consult an attorney or your mailbox provider for guidance specific to your circumstances.
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 | A.R.S. §41-371 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.

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.
