Court papers and state notices for the company land at the agent's New Hampshire address first.

Also worth asking

Can I be my own agent?

Yes, if you meet the state's rules on who may serve and on the address, both shown above.

Which addresses does the state accept?

The address has to be a physical street address in New Hampshire; filings that list an out-of-state address are not processed. P.O. boxes are not accepted.

What do the picks cost over three years?

Mainstay Filing stacks up to $447, New Hampshire Registered Agent.co stacks up to $297, NH Registered Agent.org stacks up to $297

What do these numbers rest on?

Official New Hampshire paperwork stands behind every state fee here, and every service price traces back to the company's own pricing.

Do I have to use a service?

No law requires a service. It is a paid convenience.

Which registered agent should I open first in New Hampshire?

Mainstay Filing, because one account at $149 a year covers whichever state the LLC registers in. Then New Hampshire Registered Agent.co and NH Registered Agent.org.
