Delaware Secretary of State Business Search

Start using the Delaware Secretary of State business search functionality and the database of Delaware-based entities if you are seeking to register or partner with a business in the state.

The State of Delaware has compiled an official database of businesses within their boundaries and the contact information to facilitate partnerships.

The Delaware Secretary of State is a popularly elected constitutional office of the State of Delaware and compiles databases of information pertaining to Delaware-based corporate entities through the Business Services Division.

In addition to the Business Services Division, the Delaware Secretary of State’s office also maintains Administrative Services Division, Elections Division, and a Government Records Section.

The SOS database provided by the Delaware Secretary of State Business Services Division is tasked with compiling information on all of the businesses incorporated within the state of Delaware, so all entries are exhaustive and up-to-date. Users can search the database based upon a range of search criteria that are both specific and vague, and even obscure information such as the incorporating agent.
