New Hampshire LLC Name Search

Home » New Hampshire LLC » New Hampshire LLC Name Search

The first step to forming a New Hampshire LLC is to search your desired LLC name and make sure it is available for use.

Your New Hampshire LLC name must be unique and must follow certain state requirements.

New Hampshire LLC Name Requirements

Before searching your LLC name in New Hampshire, there are a few requirements you need to know:

1. The abbreviations “LLC” or “L.L.C.” must be used at the end of your New Hampshire LLC name. The abbreviation “LLC” is the most common.

2. Because a New Hampshire LLC is not a Corporation, your desired LLC name cannot use the word “Corporation”, “Incorporated,” or their abbreviations (“Corp.”, “Inc.”).

3. Your desired LLC name must be distinguishable. This means it must be different and unique from all other businesses registered in New Hampshire.

Differences in designators (the identifiers at the end of a business name) and differences in grammar do not create distinguishability.

For example:

  • LLC, L.L.C, Inc., Corp.
  • singular, plural, and possessive
  • A, An, The
  • and, or, &
  • hyphens, slashes, periods, commas
  • three vs. 3

The following examples are NOT distinguishable:

  • Smith Investments, LLC vs. Smith Investments, Inc.
  • Apple Farm, LLC vs. Apple Farms, LLC
  • Print Shop, LLC vs. The Print Shop, LLC
  • Night & Day, LLC vs. Night and Day, LLC
  • Peter Paul & Mary Studios, LLC vs. Peter-Paul-Mary Studios, Inc
  • Three Teachers Consulting, LLC vs. 3 Teachers Consulting, LLC

Restricted Words for New Hampshire LLCs

Certain words are “restricted” when creating an LLC in New Hampshire.

Searching the New Hampshire Name Database

1. Visit the Database
Go to the Business Name Search page:

2. Search your LLC
Leave “Starts with” selected. Then enter your desired LLC name into the “Business Name” field and click the “Search” button.

Leave out the designator (“LLC”, “L.L.C.”, etc.) and leave out any punctuation.

Capitalization doesn’t matter. You can search in uppercase or lowercase.

To be thorough, just enter the first word or two of your LLC name to ensure you see everything that is potentially similar. (Ex: if your desired New Hampshire LLC name is “Johnny Apple Farm LLC”, just enter “johnny apple”).

To be even more thorough, just enter a part of the first word. (Ex: if your desired New Hampshire LLC name is “Printing Solutions LLC”, just enter “print”).

3. Browse the Results
Click the “Search” button and browse the list of existing New Hampshire businesses:

If the results show names that are not too similar to yours (meaning yours is distinguishable), then your desired LLC name is available for use.

If a “No data found with your search criteria.” message appears in the New Hampshire database, that means your desired LLC name is unique and available for use.

If your desired LLC name appears in the list exactly as you want it, your desired New Hampshire LLC name is not available for use. You’ll need to think of a new name or use some creativity and come up with a unique variation.

If the results show a name that is deceptively similar to yours, your desired New Hampshire LLC name is not available for use. You’ll need to think of a new name or use some creativity and come up with a unique variation.

If you’re not 100% sure that your desired New Hampshire LLC name is distinguishable, just file your paperwork with the state. If your name is not available, the New Hampshire Secretary of State will send back your filing and let you know that the name needs to be changed.

  1. Hi!

    Great information. I was approved for my LLC and given a EIN. In the state of NH Doss my LLC and need to be my store name? If it does, can it be an abbreviation in my store name?

    Thank you,

    • Thank you Jessica. When you say “in my store name”, what exactly do you mean? If you want your LLC to do business under a name other that’s its true, legal name, you’ll want to look into filing a Trade Name for your LLC. Hope that helps.

      • Wow, how illiterate did I look!? I was writing my question at the gym in the middle of sets. Let’s me start again.

        I have my LLC and EIN number. I sell on-line on different platforms. Does my online stores names on each of these platforms have to have my LLC name in the title in order to write off cost of good and such at the end of the year?


        • All good. Gotta get that work out in ;) Registering a Trade Name doesn’t impact your ability to deduct business expenses, Jessica. It’s about having the names your LLC operates under properly registered. Hope that helps.
