Virtual Mailbox & Form 1583 Rules in Kentucky
A commercial mail receiving agency (CMRA) or private mailbox (PMB) in Kentucky cannot serve as your LLC's registered agent with the state. However, a CMRA address may generally be used as your business address, though you should verify current requirements with Kentucky's Secretary of State office. When opening a virtual mailbox account, the USPS Form 1583 typically requires notarization or witnessing by the CMRA owner. Kentucky permits remote online notarization (RON) under permanent authority established by SB 114 (2019), and residents can complete Form 1583 notarization entirely online through an in-state RON notary.
Because notarization rules and state regulations change regularly, confirm current requirements directly on the official Kentucky Secretary of State website and with your chosen CMRA provider before proceeding. This overview is factual information only and not legal advice. Consult a Kentucky-licensed attorney for guidance specific to your LLC structure and compliance obligations.
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 | KRS §423.300 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.

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.
