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 State of Delaware. This is why it's highly important to perform a Delaware 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 in Delaware. 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, Delaware Comptroller, Delaware 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 Delaware Business Names

As mentioned above, Delaware requires LLCs to comply with the general naming rules. In addition to these rules, the Delaware Code also states that no entity may use the word "bank" or any variation of it.

How to Come Up with a Business Name

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

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

Delaware Business Search

Once you have an idea of your preferred business name, you’ll need to perform a Delaware business entity search to make sure the name hasn’t been taken by another formed business.

Bizee offers a fast, simple and convenient tool to look up your proposed business name. The Delaware Division of Corporations also has a tool that lets you search the State of Delaware business registry to see whether another formed business already has your desired business name.

Trademarks and Service Marks

You must be careful that your Delaware 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.

Delaware DBA or Fictitious 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, trade name or assumed name. In Delaware, it's called a fictitious name. You may decide to use a Delaware fictitious name for a variety of reasons.

For example, your business might be called Eastern Marketing Solutions, LLC, and under that company, you have an event planning business called Eastern Events. You could file for a fictitious business name just for that company. You'll need to register your fictitious business name with your county within the State of Delaware, 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.

Register Your Business Name With the Delaware Division of Corporations

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

  1. If you don’t want to form your LLC right now, you can reserve the business name. You can reserve your name with the Delaware Division of Corporations. Your name will be reserved for 120 days once the application is processed. If you’re forming your Delaware LLC right away, you won’t need to reserve a name.
  2. If you’re ready to start your LLC now, you can file your Articles of Formation with the Delaware Division of Corporations or have Bizee do it for you.
