General Rules for Corporation Names

These rules generally apply to all corporations, wherever they're formed.

Your Corporation Name Must Be Unique

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.

Your Name Must Not Be Confusable with Another Business Name

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.
Your Corporation Name Must Contain Certain Words

All corporations must use one of the following in their names, usually at the end of the name: “Incorporated,” “Corporation,” “Limited” or their abbreviations.

Your Corporation Name May Be Subject to Other General Restrictions

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

Specific Rules for New Hampshire Business Names

Although New Hampshire doesn't have any distinct naming regulations, you'll still need to follow some New Hampshire corporation laws that apply to naming your business.

For example, per the New Hampshire Revised Statutes Title 27, Title 293-A, § 293-A:4.01, a corporate name:

"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."

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 Bizee. If the trademark isn't already in use, you can even register it yourself.

Make sure your corporation is starting off on the right foot when it comes to intellectual property.

Let Bizee run a trademark search for you.


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 Bizee 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.
