Virtual Mailbox & Form 1583 Rules in North Carolina
A commercial mail receiving agency (CMRA) or private mailbox (PMB) in North Carolina cannot serve as your LLC's registered agent address. However, a CMRA address may generally be used as your business mailing address, though you should verify current requirements with the North Carolina Secretary of State's office. When opening a virtual mailbox with USPS, you will need to complete PS Form 1583. While notarization is often required for this form, the USPS may accept either a notary's signature or the CMRA owner's witnessing—confirm the current requirement directly with your local USPS branch or the USPS website.
North Carolina allows remote online notarization (RON) for the Form 1583, with permanent RON authority in effect since 2022. This means you can complete the entire mailbox sign-up process online using an in-state RON notary without visiting a physical location. Because postal and notary regulations change, verify the latest requirements on the official USPS and North Carolina Secretary of State 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.

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.
