Montana registered agent rules (official, Montana 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, including an owner, or an entity in Montana. See Mont. Code Ann. § 35-7-105.
The address has to be an actual street address or rural route box number in Montana. A P.O. box alone is not enough.
