Steps to conducting a Delaware business entity search

Your Delaware business name is how customers identify your company, which is why you should give your name a great deal of thought. Here are a few key steps to take to ensure company name success in Delaware.

1. Search for a business name

Once you have chosen a name for your proposed business, you must ensure your business name has not already been registered with the Delaware Division of Corporations.

2. Ensure your business name is unique and compliant

Use the Delaware Division of Corporations' business name search tool to confirm your chosen name does not clash with existing business entities or formed businesses and meets state naming requirements, such as including "LLC" or "Corporation."

• To begin your search, visit the Delaware name search website. Type in the potential entity name.
• The system will give you a list of business names that match or are close to the name of your potential business and the file number.
• Click on the business name to also see the incorporation/formation date, registered agent name, address, phone number, and residency.
• The business names are offered free of charge.
