Massachusetts Secretary of State Business Search and Registering Your LLC Name

We’re here to help you find the right business name for your Massachusetts LLC. From searching for a business name with the MA Corporations Division to understanding naming rules or creating a “Doing Business As” name to register your entity, you’re in the right place.

Conducting a Business Entity Search on the MA SOS Website

You should start naming your business by completing a “Massachusetts business entity search” with the Corporations Division. They have a helpful tool on their website that lets you search the register of MA LLCs and corporations to see if someone already has your desired business name. 

If the business name is already used, that means it’s not available and you won’t be able to register it. Try searching for a different business name instead.

Massachusetts Corporations Division Rules for LLC Business Names

Once you’ve decided on a name for your LLC and checked business name availability, you’ll need to meet Massachusetts Corporations Division naming rules. These do vary from state to state — we’ve got general naming rules below, as well as naming rules specific to LLC businesses formed in MA.

General Rules for Naming Your LLC

These rules typically apply to all LLCs, no matter what state they are formed in. You will need to pay attention to these rules, as they will influence the name you choose for your Massachusetts LLC.

Your LLC Business Name Must Be Unique

The business name you have chosen cannot be used by any other LLC or corporation in the state of Massachusetts. This is why you should check business name availability on the MA Corporations Division website.

Your LLC Business Name Must Not Be Confusable With Another Business Name

It’s not enough for your MA LLC name to be unique. It also cannot be similar to the name of a corporation or LLC in Massachusetts. For example, you cannot use the following factors to say your name is different from the name of another business:

• Suffixes, such as Corporation, Company, Incorporated, Incorporation, Limited, Corp., Co., Inc., Ltd., LLC, etc.

• Definite articles like “A,” “And,” “An,” “&,” “The,” etc.

• The singular, plural or possessive forms of a word

• Abbreviations, punctuation, symbols, fonts, typefaces, etc.

Your LLC Business Name Must Contain Certain Words

All LLCs must have the words “Limited Liability Company,” “L.L.C.” or “LLC” in their name. These words should normally come at the end of the name.

Your LLC Business Name May Have Other General Restrictions

Most states will not allow you to form LLCs with names that:

• Are very similar to the name of a federal or MA agency or organization (e.g., FBI, FDA, Massachusetts Department of Revenue, Massachusetts Police, Treasury, etc.)

• Suggest affiliation with a federal or state agency or organization

• Use the term “Olympic” or any terms that are trademarks of the Olympic organization

• Imply a purpose that it would be illegal for your business to carry out

DBA/Fictitious Business Names in Massachusetts

You might choose to do business under a different name from your legal LLC name. In Massachusetts, doing business under a different name is known as a “Fictitious Name” or a DBA (”Doing Business As”) name. You might choose to use a different name from your MA formal LLC name for a variety of reasons.

For example, your LLC might be called Massachusetts Bioscience Holding Company LLC, and you have a specialized service called “Genetic Medicine Research Services.” You should file a Fictitious Name to let the Massachusetts Corporations Division know.
