Step 3: Review Results

When we search the registered names, we get a list of all the businesses with the words “Lawn Envy.” To register a corporation or LLC name in New Hampshire, the name must be distinguishable from the other registered names. If your search comes up with a business name that is exactly like the one you want, be sure to look at the last column named “Status.” If it says anything other than “Good Standing,” you may be able to register it.

In this example, if you were looking to form an LLC named Lawn Envy name, you wouldn’t be able to since there is already one registered.

While the name “Lawn Envy” by itself may not be available, other variants are such as “Lawn Envy of New Hampshire” or “Lawn Envy Pros” are.  Searching for those business names brings a result that says, “There were no records found.”  While final approval is still with the Secretary of State, it is likely available to register. 

New Hampshire Business Name Availability


These are the basics of searching for a business name in New Hampshire.  Even when the name of the business you want is available, the Secretary of State will make a final determination at the time of filing to ensure the name you picked isn’t too similar to other registered names. 

Something to keep in mind is that even though each Corporation and LLC name must be unique, it may not stop someone else from using that name since business names for a sole proprietorship or partnership are not registered by the New Hampshire Secretary of State and are not required to be unique.  To protect your business name, consider getting a trademark.

New Hampshire Business Name Search FAQs

How do I find the business name of a New Hampshire sole proprietorship?

A New Hampshire sole proprietorship or general partnership can use the small business owner(s) full first and last name as the business name, but many will want to operate under a specific business name. In order to register the business name, they will register for a New Hampshire Trade Name, which is also known as “Doing Business As,” DBA, Assumed Name, or Fictitious Business Name.

Similar to the New Hampshire corporation or LLC, Trade Name registrations need to be unique and are registered through the Department of State’s office.
