Delaware Business Entity Search

The Corporations Division of the Delaware Department of State maintains the record of business entities filed in the state. The database contains the history of every company or entity that is registered under the Delaware Secretary of State and you can also search to see if the name you want to use for your business is available.

The Division holds information regarding the following entities:

  • Corporations
  • Limited Liability Companies
  • Limited Company
  • Limited Partnerships
  • Limited liability partnership

Sole proprietorships and general partnerships are not registered with the Division of Corporations as they are not individual business entities.  To find the owner information for sole proprietorships and partnerships, go to the Prothonotary’s Office in the county where the business is located to find the Doing Business As registration records.

Registered Agent

Delaware law requires a Registered Agent to be named for a registered entity.  This is a single point of contact in case the business needs to be served with legal papers or contacted by the state.  One of the business owners often file as the entities registered agent.  When they file, their home address is often used (PO Boxes aren’t allowed) and their name address is now a public record that can be looked up by anyone.  If that is a concern, consider looking into a Registered Agent service.

Step 5 – You can also download the annual report of an entity from the website (also, you can download important documents such as the status and tax history information for an additional fee).
