What Maine requires of your registered agent (Maine Secretary of State)

Every LLC must name a registered agent with an in-state street address.

A commercial registered agent listed with the Secretary of State, or a noncommercial agent: an individual or entity serving as agent in Maine, or the holder of a named position in the company. Statute behind it: 5 M.R.S. § 105.

A noncommercial agent lists a physical street address in Maine, not a P.O. box. Commercial agents keep their address on file with the state.
