Delaware Entity Searches & Naming Your Delaware LLC

Your Delaware business entity needs the perfect name, and we’re here to help. In this section we’ll guide you through using our tool to search 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. We make that fast and easy with the Incfile business name search tool. Just enter your details and we’ll search the business registry and see if your desired business name is available. We can even search your name for other states from one central place.

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. Alternatively, you can use the Delaware Secretary of State Entity Search tool. All you need to do is enter the DE business name in the “Entity Name” field and click “Search.

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.

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 and checked availability through our business search tool, it’s time for next steps. You will need to follow naming rules and decide whether or not you need a fictitious name. Once you’ve done that, you can register your DE LLC name. There are a couple of ways to do this.

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. If it doesn’t infringe, you can even register it as a trademark yourself.
