Updated September 6, 2026. Quick answer: In New Hampshire, this role is called a registered agent, governed by New Hampshire RSA 304-C:36 (limited liability company registered offices and registered agents), RSA 304-C:37 (service of process on domestic LLCs), and RSA 304-C:136 (grounds for administrative dissolution, including being without a registered agent/office for 60 days or more). New Hampshire’s default remedy when there’s no agent is mail-to-principal-office service rather than routing through the Secretary of State as a substitute agent, and it lists “no agent/office for 60+ days” as its own explicit dissolution ground distinct from the separate “failed to report a change within 60 days” ground; a more granular structure than most of the other states here.
What the address rule requires
The registered office must be a physical address in New Hampshire, not a P.O. box, and may be the same as any of the LLC’s places of business; a registered agent who is an individual must have a residential or business office identical with that registered office.
Who can serve as your registered agent
An individual who resides in New Hampshire with an office identical to the registered office; a corporation organized/authorized under RSA 292, 293-A, or 294-A; an LLC or professional LLC formed/authorized under RSA 304-C or 304-D; or a limited liability partnership under RSA 304-A:44; in each case with a business office identical to the registered office.
What happens if you don’t have one
If an LLC has no registered agent, or the agent cannot with reasonable diligence be served, the LLC may instead be served by registered or certified mail, return receipt requested, addressed to it at its principal office. Being without a registered agent or registered office in New Hampshire for 60 days or more is itself a distinct statutory ground for administrative dissolution (separate from the ground of failing to notify the state of a change within 60 days); administrative dissolution does not terminate the authority of the LLC’s registered agent.
