New Hampshire LLC Name Search

Nailing down a great name for your New Hampshire LLC can be challenging. 

You want the name to be unique and easy to remember while being legally acceptable and conveying what your business does. You also want it to be SEO-friendly so that it can easily be found on Google. That’s a lot of boxes to check. 

And even if you’ve already found the perfect business name, you need to make sure it’s available. That takes several steps, as detailed in this handy guide.

New Hampshire LLC Entity Search 

The most important consideration when choosing an LLC name in New Hampshire is to make sure it’s available and legally acceptable. Here’s how to confirm you can use your preferred business name. 

1. Check for availability in New Hampshire

Go to the New Hampshire Secretary of State’s website and enter your business name. 


You should also search for similar business names, as you don’t want a name that can be easily confused with other businesses in New Hampshire.

2. Check New Hampshire’s LLC name regulations

In New Hampshire, your LLC name must be distinguishable from all other business names in the state and contain either “limited liability company” or an abbreviation (LLC or L.L.C.).

Your business name also must not imply any other business activity than the one you’re legally permitted to engage in or confuse your business with any government entity. Additionally, your name cannot contain vulgar language or words like bank or credit union.

3. Check Trademarks

Check with the US Patent and Trademark Office to ensure the name has not been trademarked and is thus available nationally. 

4. Check domain name availability

You’ll want to make sure the domain name is available. You can check at a site like and use .com or .org, as those give your business more credibility.

5. Google it

Do a Google search to ensure the name is not being used in the U.S. or internationally. This is particularly important if you plan to have a strong online presence for your business.  

Once you’ve confirmed these, it’s a good idea to reserve the name with the state. 

How to file a New Hampshire LLC Name Reservation

To reserve an LLC name in New Hampshire, start by visiting the Secretary of State’s website, then head to the name reservation form to complete the online application.


Enter the required information and your electronic signature, and click submit to go to payment. Alternatively, you can complete and mail a paper form that you can download from the link above. 

The cost to file a name reservation in New Hampshire is $15. Once your application is processed, your LLC name will be reserved for 120 days.

Doing Business As (DBA)

Even after all this work, you may want to do business under a name other than your LLC. First, you’ll need to register a “doing business as” or DBA name. There are two main reasons you might want to use a DBA.

  • Suppose you want to add new product lines. For example, if your business name is “JJ’s Waffles,” you want to expand and offer “JJ’s Muffins.”  You can have multiple DBAs under the umbrella of your one LLC. 
  • When you have a DBA, you can have a business bank account under that name. So if you add “JJ’s Muffins,” customers can pay “JJ’s Muffins,” and you can deposit those payments into the bank account with that name.

In New Hampshire, a DBA is known as a trade name. To register a trade name in New Hampshire, go to the Secretary of State’s website and complete the registration online. The fee is $50.


In Closing

Choosing a business name is crucial to entrepreneurial success, so if you’ve found a good one, don’t let somebody else get it. Instead, just take the steps detailed above to ensure it’s available and legally acceptable before nailing it down. 

You don’t want to run into an issue later that could impact the success of your business.
