General Rules for LLC Names

These rules typically apply to all LLCs, no matter what state they're formed in.

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 Maryland. This is why you should check business name availability on the MD Business Express website.

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

It’s not enough for your MD LLC name to be unique. It also cannot be similar to the name of a corporation or LLC in Maryland. 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 MD agency or organization (e.g., FBI, FDA, Maryland Comptroller, Maryland 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

Specific Rules for Maryland Business Names

The general rules listed above are also rules enforced by the state of Maryland and are detailed in the state's code on Corporations and Associations, Title 1, Subtitle 5, Section § 1-502.

Maryland Business Search

Once you have an idea of the business name you’d like to use, you’ll need to complete a Maryland business entity search to make sure the name isn't already taken by another business.

Incfile offers a fast, simple and convenient tool to look up your proposed business name. The Maryland DAT also has a tool through which you can perform a Maryland entity search to see if someone already has your desired business name.

Trademarks and Service Marks

You must be careful that your Maryland LLC name doesn't infringe on the trademark or service mark of another business. The easiest way to make sure your proposed business name doesn't infringe is to carry out a trademark search through Incfile. If no one else is using it, you can even register it as a trademark yourself.

Make sure your business is starting off on the right foot when it comes to intellectual property.

Maryland DBA or Trade Name

You may do business under a name other than your legal LLC name. In some states, this is called a DBA (doing business as), fictitious, or assumed name. In Maryland, it’s called a trade name. You might choose to use a trade name for a variety of reasons.

For example, your business might be called Maryland Commercial Real Estate Holding Company, LLC and you have a chain called Baltimore Property Rentals. You should file a trade name to let the Maryland DAT know. In Maryland, you do that with the Trade Name Application, or you can have Incfile do it on your behalf through our DBA service.

Note: A trade name is not the same as a trademark. Learn more about trademark vs. DBA.

Register Your Business Name with the Maryland DAT

Once you’ve completed a Maryland business name search, checked availability, followed the naming rules and decided whether you need a trade name, you can register your LLC name. There are a couple of ways to do this.


If you don’t want to form your LLC right now, you can reserve the business name with the Maryland DAT. You'll need to complete a Corporate Name Reservation Application. Once you do so, your name will be reserved for 30 days. You don't need to reserve a name if you're forming your business right away.


If you’re ready to start your LLC, you can file your Articles of Organization with the Maryland DAT or have Incfile do it for you.

Incfile can handle all your formation paperwork with the State of Maryland for you — and we’ll do it for free!
