Oklahoma registered agent requirements, as written by the state (Oklahoma Secretary of State)
Every LLC must name a registered agent with an in-state street address.
The LLC itself, an Oklahoma resident, or a corporation, LLC or partnership formed in Oklahoma or qualified there. See 18 O.S. § 2010.
The address has to be a street address in Oklahoma, at a business office that is open during regular business hours. P.O. boxes are not accepted.
