Updated September 6, 2026. Quick answer: In Missouri, this role is called a registered agent, governed by RSMo Section 347.030 (maintenance/change of agent), Section 347.033 (service on agent, Secretary of State as default), Section 347.183 (administrative cancellation). Missouri’s default-service mechanism forwards mail to an ‘organizer’ address from the LLC’s original, potentially years-stale articles of organization, a distinctive practical wrinkle among the states compared here, alongside an explicit 30-day advance-notice-before-cancellation window.
What the address rule requires
Missouri requires the address of the registered office and the business office of the registered agent to be identical.
Who can serve as your registered agent
An individual resident of Missouri whose business office is identical with the registered office, or a domestic or foreign corporation authorized to do business in Missouri. Missouri’s statute names individuals and corporations, not LLCs, as eligible agent types.
What happens if you don’t have one
If an LLC fails to maintain a registered agent, the Secretary of State is automatically appointed as an agent of the LLC upon whom process, notice, or demand may be served; service on the Secretary of State is then forwarded by registered mail to an organizer’s address listed in the LLC’s original articles of organization. The Secretary of State may administratively cancel the LLC’s articles of organization for failing to maintain a registered agent, after written notice at least 30 days before the cancellation takes effect.
How to change your registered agent
A statement of change is filed with the Secretary of State under Section 347.030; reported fees on official Secretary of State forms include $10 for the paper Corp. 59 form and $25 for the LLC-specific online form, though the fee-schedule PDF itself could not be text-extracted this session to independently confirm the split.
