General Rules for Corporation Names
These rules generally apply to all corporations, wherever they're formed.
The name you select cannot be in use by any other business in the state. This is why it's so important to perform a New Hampshire Secretary of State corporation search before you begin your incorporation paperwork.
It’s not enough for your corporation name to be unique. It also cannot be similar to the name of another business in the state. In addition, you cannot use any of the following features in an attempt to differentiate your corporation name from that of another business:
- Suffixes, such as Corporation, Company, Incorporated, Incorporation, Limited, Corp., Co., Inc., etc.
- Definite articles, such as “A,” “An” or “The”
- The conjunction "And" or “&"
- Numbers in place of numerals (or vice versa), e.g., "One World" is the same as "1 World"
- The singular, plural or possessive forms of words
- Abbreviations, punctuation, symbols, fonts, typefaces, etc.
All corporations must use one of the following in their names, usually at the end of the name: “Incorporated,” “Corporation,” “Limited” or their abbreviations.
Most states will not allow you to incorporate with names that:
- Are similar to the name of a federal or state agency or organization (e.g., FBI, FDA, New Hampshire Department of Labor, New Hampshire Rangers, Treasury, etc.)
- Suggest affiliation with a federal or state agency or organization
- Use the term “Olympic” or any terms that are trademarks of the International Olympic Committee
- Imply a purpose that would be illegal for your business to carry out

"must contain the word "corporation," "incorporated," or "limited," or the abbreviation "corp.," "inc.," or "ltd.," or words or abbreviations of like import in another language."

New Hampshire Corporation Name Search
Once you have an idea of the name you want, perform a New Hampshire business lookup to make sure another company isn't already using that name.

Trademarks and Service Marks
You must be careful that your New Hampshire corporation name doesn't infringe on the trademark or service mark of another business. The easiest way to ensure you're not infringing is to perform a trademark search through Incfile. If the trademark isn't already in use, you can even register it yourself.

Register a DBA in New Hampshire
You may do business under a name different from your corporation's legal name. While many states refer to this as a fictitious name, assumed name or "doing business as" (DBA), it's a trade name in New Hampshire. You may decide to use a trade name for a variety of reasons.
For example, your primary business may be called High Line Technologies, Inc., and you have a chain called High Line Installations. You could register a trade name just for that brand. You'd do that with the Application for Registration of Trade Name form, or you can have Incfile do it on your behalf with our DBA service.
In order to keep your business names unique, you can also use the New Hampshire SOS online portal. Perform a New Hampshire trade name search to find out whether any other companies are already using the trade name you want. We can also help you with this via our DBA name service.
Note: A trade name is not the same as a trademark. Learn more about trademark vs. DBA.
