The Kentucky registered agent rule as the state states it (Kentucky Secretary of State)
Every LLC must name a registered agent with an in-state street address.
A Kentucky resident, or an entity qualified to do business in Kentucky, whose business address is the registered office. The agent signs or files a written acceptance. The law on point is KRS 14A.4-010.
The address has to be a physical registered office in Kentucky that matches the agent's business address. A P.O. box is not enough.
