How to Search for and Register Your Delaware LLC Business Name

Your Delaware business entity needs the perfect name, and we’re here to help. In this section we’ll guide you through searching the DE Division of Corporations business register, tell you about the rules for naming your business, describe “Doing Business As (DBA)” names and get you started with registering your LLC.

Delaware LLC Business Search

You should start naming your business by completing a “Delaware business entity search” with the Division of Corporations. They have a helpful tool on their website that lets you search the register of DE LLCs and corporations to see if someone already has your desired business name. All you need to do is enter the DE business name in the “Entity Name” field and click “Search.

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.

Follow These Rules to Name Your Delaware LLC

Once you’ve decided on a name for your LLC and checked business name availability, you’ll need to meet Delaware Division of Corporations 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 DE.

Standard LLC Naming Rules

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 Delaware 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 Delaware. This is why you should check business name availability on the DE DOC website.

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

It’s not enough for your DE LLC name to be unique. 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 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 DE agency or organization (e.g., FBI, FDA, Delaware Division of Revenue, 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 Olympic organization
  • Imply a purpose that it would be illegal for your business to carry out

Specific LLC Naming Rules for Delaware

In addition to the general rules listed above, the Delaware Division of Corporations has some specific business naming rules for your LLC. You will need to follow these rules if you want to name your DE business appropriately.

  • The name of your LLC may contain the names of members or the words "Club," "Foundation," "Fund," "Institute," "Society," "Union," "Syndicate," or "Trust" instead of “LLC.”
  • The name can include words in a foreign language, as long as you provide a translation into English when filing the LLC.
  • Some words, like “Bank,” “University” or “College” are restricted and need additional paperwork
  • Other words (typically those associated with certain professions and licensed individuals) require the individual to be part of the LLC — doctors, engineers or accountants, for example.
  • The name may contain the name of a member or manager.

Delaware LLC “Doing Business As” (DBA) Names

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

For example, your LLC might be called Delaware Corporate Construction Holding Company LLC, and you have a chain called Wilmington Building Supplies. You should file a DBA form with the Delaware courts in your county. You can have Incfile do this on your behalf through our Assumed Business Name service.

Business Name Registration for Your Delaware LLC

Once you’ve searched for your Delaware business name, checked availability, followed the naming rules and decided whether or not you need a fictitious name, you can register your DE LLC name. There are a couple of ways to do this.

  1. If you don’t want to form your Delaware LLC right now, you can reserve the business name with the Delaware Division of Corporations. You will need to complete a form and file it with the DE DOC. You do not need to reserve a name if you are forming your business right away.

Trademarks and Service Marks

You must be careful that your Delaware LLC name does not infringe on the trademark or service mark of another business. The easiest way to make sure your proposed business name does not infringe is to carry out a trademark search through Incfile.
