Massachusetts Business Name Search (LLC lookup) - 2025 Guide

LLC names

Once you’ve chosen a Massachusetts LLC name, you need to compare it against existing businesses in the state.

This is done using the Massachusetts Business Entity Search tool.

And this is necessary because business names in the same state:

  • can’t be the same
  • can’t be too similar

If you file your LLC paperwork with a name that’s not available, your LLC filing will be rejected.

How do I search the Massachusetts business entity name database?

You can use the Business Entity Search to compare your business name against the existing business entities registered in Massachusetts.

Note: This tool is sometimes called the Massachusetts Business Name Search or the Massachusetts Business Entity Search. They both refer to the same website and get you the same search records.

Massachusetts has a separate search tool for checking existing Business Name Reservations. But most people don’t file a name reservation. So we don’t think this tool is very useful.

Visit the Massachusetts Corporate Records Search page:

Massachusetts Secretary of State: Business Entity Search

It’s simple: enter your desired LLC name in the search bar.

Leave “Search by” set to “Entity Name“. And set “Search type” to “Full Text“.

Search tips:

  • Leave out “LLC”, “L.L.C.”, “Limited Liability Company”, etc., when doing your searches.
  • Leave out any commas, periods, apostrophes, etc.
  • You can search using uppercase or lowercase letters.


How to interpret the Massachusetts LLC search results

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

  • Let’s keep using the example above. If your desired name is Riverwalk Studios LLC, and the only similar names you saw were “Riverwalk Rentals” and “Riverwalk Studio Starters”, then your name should be available.

If no results show up, that means your LLC name is unique and it should be available for use. To be safe, run your search again using only part of your LLC name (to double-check that there are no similar names).

  • For example, search just the word “Riverwalk” instead of Riverwalk Studios.

If your exact LLC name appears in the list of search records, your LLC name is not available for use because another Massachusetts business entity is already using it.

If the results show a name that is very similar to yours, your LLC name may not be available for use.

  • If your desired name is Riverwalk Studios LLC, and the search results show a “Riverwalk Studio”, then your name is not available.

What if my desired LLC name isn’t available?

If your name is not unique, you’ll need to come up with a variation or a different name for your LLC.

Tip: Wait until your LLC is approved before you apply for your LLC EIN Number or purchase any other marketing materials. This way you don’t spend money on business supplies you can’t use because your business name isn’t available.

Massachusetts Secretary of State Contact Information

You can call the Massachusetts Secretary of State to ask questions about whether your LLC name is available.

Representatives at the Massachusetts Secretary of State can help you use the Massachusetts Business Name Search. They can’t guarantee that your LLC name will be available when you file, however.

The Corporations Division phone number is 617-727-9640. Their hours are 9am to 5pm Eastern Time, Monday through Friday.

Massachusetts Limited Liability Company Name Requirements

As per Section 156C-3 of the Massachusetts LLC Act, there are a few rules and requirements for naming a Massachusetts business entity that you need to know.

Do I have to use a comma in my LLC name?

No, you don’t have to. You can file your LLC name with or without a comma. Both versions are accepted by the Secretary of State.

For example: If your desired business name is Ladybug Linens, you can file it as:

  • Ladybug Linens LLC
  • Ladybug Linens, LLC

Or, instead of having “LLC” as your designator (ending), there are a few other options in Massachusetts.

What designators (endings) can I use in my LLC name?

Your Massachusetts LLC name must contain one of the following designators at the end:

  • LLC
  • L.L.C.
  • LC
  • L.C.
  • Limited Company
  • Limited Liability Company

The following designators are not allowed

Your Massachusetts LLC can’t make itself sound like a Massachusetts Corporation or any other business entity besides an LLC.

The following words and designators can’t be used anywhere in your LLC name:

  • Inc.
  • Corp.
  • Incorporated
  • Corporation

What words are not allowed in my Massachusetts LLC name?

Your Massachusetts LLC name can’t contain words and abbreviations that are restricted by law.

For example, you can’t make your LLC name sound like it’s a bank, part of the government or a government agency, or anything else that misleads the public.

You also can’t use words that are reserved for licensed professionals. These vary by state, but some common examples are accountants, architects, attorneys, dentists, and engineers.

Your Massachusetts business name must be distinguishable (unique)

When you search the Massachusetts Secretary of State Business Entity Search, you will compare your desired LLC name to existing businesses in the state.

If your name is not unique, you’ll need to come up with a variation or a different business name.

Below are rules and examples of LLC names that are not distinguishable.

Designators

Differences in designators (endings) don’t create distinguishability.

If your desired LLC name is Chickadee Chimneys LLC, it’s not available to use if any of the following are found in the Massachusetts Business Name Search results:

  • Chickadee Chimneys, Inc.
  • Chickadee Chimneys Corp.
  • Chickadee Chimneys, L.L.C.

Filler Words

Adding non-meaningful or filler words (the, a, an, and, &, of, or) won’t create distinguishability.

If your desired LLC name is Cranberry Farms LLC, it’s not available to use if any of the following are found:

  • The Cranberry Farms LLC
  • A Cranberry Farm Inc.
  • Cranberry and Farms L.L.C.
  • Cranberry & Farms Corp

Plural or Singular Words and Possessive Words

Adding a letter “s” to make a word plural or possessive doesn’t create distinguishability.

If your desired LLC name is Patti’s Terriers LLC, it’s not available to use if any of the following are found:

  • Pattis Terriers LLC
  • Patti’s Terrier Inc.
  • Patti Terrier, L.L.C.

What if my Massachusetts business name is rejected?

If you file your Massachusetts Certificate of Organization (the document that creates your Massachusetts LLC) and the business name is not available, don’t panic. The state will notify you and tell you why your filing was rejected.

You will just need to file again with a variation of your LLC name or a different LLC name.

  1. So, for Massachusetts, even just to ‘hold’ an LLC that’s not yet active or generating no revenue, or in the building process, it will cost at least $956 a year? ($500 annual ‘report’ and $456 minimum tax).

    thanx, K

    • Hi Luftweg, yes, you are correct. Unfortunately, Massachusetts has a very expensive Annual Report (compared to the national average). Hope that helps.

  2. Hi Matt,
    I recently purchased(deed) a house under an LLC. However I established homeowners insurance under my name due to delays with IRS issuing EIN numbers. Can I keep this under my name(I am a member of LLC),
    Thanks Dan

    • Hi Dan, the delays with the IRS have been a major pain. However, we recommend having the LLC hold the insurance policy. You can switch things over once you have the EIN. Hope that helps.

  3. Hey Matt,

    How are you? I hope all is well. I just filed my LLC for a Web Design business with my partner. It will just be him and I doing all the work. No employees for the first year. I was wondering how we go about taxes? I filed my LLC through legalzoom.

    I bought their “compliance, tax and legal” advice. They are all $320/each per year. I know I need the legal advice in case my business gets sued. But do I really need the tax and compliance advice? Let me know.

    Thank you, mate!

    Best,
    Adriel

    • Hi Adriel, I don’t know the ins and outs of those 3 packages, however, I believe the compliance they are referring to is the Massachusetts LLC Annual Report. I’m not sure what is included in the tax advice, but our recommendation is to hire an accountant. You could also keep the packages (and use them) to see if there is value in it for you, and then choose to renew or cancel next year. Hope that helps :)
