Search for and Register Your New Hampshire LLC Name

Whether you’re searching for the right New Hampshire business name or registering your LLC with the NH Secretary of State, we can help. We’ve got all the information you need on a New Hampshire business entity search, LLC naming rules, fictitious names and registering your business.

New Hampshire Secretary of State Business Search

You should start naming your business by completing a business entity search with the Secretary of State. They have a helpful tool on their website that lets you search the register of NH LLCs and corporations to see if someone already has your desired business name.

If the business name is already used, that means it’s not available and you won’t be able to register it. Try searching for a different business name instead.

Business Name Registration Rules for Your New Hampshire LLC

Once you’ve decided on a name for your LLC and checked business name availability, you’ll need to meet New Hampshire Secretary of State naming rules.

New Hampshire Trade Names for LLCs

You might choose to do business under a different name from your legal LLC name. In New Hampshire, doing business under a different name is known as a “Trade Name.” You might choose to use a different name from your NH formal LLC name for a variety of reasons.

For example, your LLC might be called New Hampshire Secretarial Services Holding Company LLC and you have a brand called Admin Expertise. You should file a trade name to let the New Hampshire Secretary of State know. In New Hampshire, you do that through a Form TN-1 Trade Name Registration, or you can have Incfile do it on your behalf through our Assumed Business Name service.
