Search by File Number

If you know the file number assigned by the Secretary of State, you can search by that number.

Search by New Hampshire Registered Agent

You are also able to search by Registered Agent.  Since Registered Agents file for many corporations and LLCs, this is often a long list. This agent is a single point of contact in case the business needs to be served with legal papers or contacted by the state. One of the business owners often files as the entity's Registered Agent. When they file, their home address is often used (PO Boxes aren’t allowed), and the owner's name and address are now a public record that can be looked up by anyone. This can be a big concern, especially for home-based businesses. Using a commercial Registered Agent service like Northwest Registered Agent will keep their personal address from being public record.

Business Licenses

The business name registration is different from business licensing in New Hampshire.  The New Hampshire Department of Revenue has more information regarding New Hampshire business licenses.
