How to check a registered agent in New Hampshire

Mainstay Filing is our pick in New Hampshire at $149 a year. To check any agent here: ask the New Hampshire Secretary of State how it records agents, confirm a New Hampshire street address, then apply the five criteria.

The New Hampshire rule

Every LLC must name a registered agent with an in-state street address. A New Hampshire resident, or a business entity registered with the Secretary of State, whose office is the registered office. 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. Changing agents costs $15. Source: N.H.
