If the name you want for your Delaware corporation is already used by a DE LLC or corporation, you will need to choose a different name.Delaware Division of Corporations corporation name search tool
Delaware Naming Rules Before You Register Your S Corp or C Corp
Once you’ve found an original name for your Delaware S Corp or C Corp, you will need to make sure it meets Delaware Division of Corporations naming rules.
General Rules for Naming Your S Corp or C Corp
The rules below generally apply to all corporations, wherever they are formed.
All DE Registered Corporations Must Have a Unique Name
The name you have chosen for your S Corporation or C Corporation cannot be used by any other registered business in the state of Delaware. This is why you must check business name availability on the DE Division of Corporations website.
The Name of Your Corporation Cannot Be Similar to Other Businesses in Delaware
Not only must your DE corporation name be unique, it cannot be similar to another corporation or LLC name in Delaware. 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.
For example, you can’t claim that Purple People Co., Purple People Corporation, Purple People Incorporated, Purple People Corp. or Purple People are different from one another.
Your Delaware Corporation Name May Have Other Restrictions
Most states will not allow you to form S Corporations or C Corporations with names that:
- Are very similar to the name of a federal or DE agency or organization (e.g., FBI, FDA, Delaware Department of Revenue, Delaware Police, Treasury, etc.)
- Suggest affiliation with a federal or DE 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 Delaware corporation to carry out
Specific Rules for Naming Your Delaware Corporation
The general rules above are a good starting point for naming your DE S Corporation or C Corporation, but they are not the only ones. The Delaware Division of Corporations has some specific business naming rules for corporations. You will need to follow these rules if you want to name your DE business appropriately.
- The name of your business must include one of the following words: "association," "company," "corporation," "club," "foundation," "fund," "incorporated," "institute," "society," "union," "syndicate" or "limited"
- You cannot use the word “bank” or “trust” in your business name without special permission
Delaware Corporation Fictitious and “Doing Business As” (DBA) Names
You may want your Delaware S Corporation or C Corporation to conduct business under a different name from the name it was formed under. In Delaware, this is known as a “fictitious” or “doing business as” name. We can complete this filing on your behalf.Incfile’s Assumed Business Name Service
Rules on Infringing on Service Marks or Trademarks Inside or Outside Delaware
The naming rules above are not the only areas you need to consider when naming your Delaware S Corporation or C Corporation. You also need to check if your DE business could infringe on the registered service marks or trademarks of another business.
The easiest way to see if your proposed business name infringes is to carry out a trademark search. You can do that via the United States Patent and Trademark Office, or Incfile can help you protect your business with our Trademark Search and Registration service. You should also bear in mind that your Delaware corporation name cannot be substantially similar to an existing trademark or service mark.
