We have all the information you need to know on how to conduct a District of Columbia business search, plus LLC naming rules, DBA names and registering your business.

General Rules for LLC Names

These rules typically apply to all LLCs, regardless of which state they're formed in.


Your LLC Name Must Be Unique

Your preferred business name cannot be used by any other LLC or formed entity in the District of Columbia. This is why it's highly important to perform a Washington, D.C., business entity search before you begin the filing process.


Your LLC Name Must Not Be Confusable With Another Business Name

Your LLC name should be unique, but that’s not enough. It also cannot be similar to the name of a corporation or LLC within the District of Columbia. For example, you cannot use the following factors to say your name is different and distinguishable from the name of another business:

  • Suffixes, such as Corporation, Company, Incorporated, Incorporation, Limited, Corp., Co., Inc., Ltd., LLC, etc.
  • Definite articles, such as “A,” “An,” or “The”
  • The conjunction "And," or “&"
  • The singular, plural or possessive forms of words
  • Abbreviations, punctuation, symbols, fonts, typefaces, etc.

Your LLC Name Must Contain Certain Words

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


Your LLC 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 state agency or organization (e.g., FBI, FDA, Washington, D.C., Comptroller, District of Columbia 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 International Olympic Committee
  • Imply a purpose that would be illegal for your business to carry out

Specific Rules for Washington, D.C., Business Names

As mentioned above, Washington, D.C., requires LLCs to comply with the general naming rules. In addition to these rules, the Code of the District of Columbia also states that no entity may use the word "bank" or any variation of it, unless with prior approval of the Mayor.

How to Come Up With a Business Name

Finding the perfect business name can be elusive. We have a complete guide to choosing the right business name, but essentially, you'll want to choose a name that will:

  • Best represent your product or services
  • Be memorable enough to stand out
  • Appeal to your customers
  • Not be used by any other business

Trademarks and Service Marks

You must be careful that your Washington, D.C., 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 do that is to complete a trademark search through Bizee. If no one else is using it, you can even register it as a trademark yourself.

Washington, D.C., DBA or Trade Name

You may do business under a different name from your legal LLC name. In some states, this is called a DBA (doing business as) name, fictitious name or assumed name. In the District of Columbia, it's called a trade name. You may decide to use a Washington, D.C., trade name for a variety of reasons.

For example, your business might be called Currant Marketing Solutions, LLC, and under that company, you have an event planning business called Currant Events. You could file for a trade business name just for that company. You'll need to register your trade name with Washington, D.C., Department of Consumer and Regulatory Affairs, or you can have Bizee 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.
