Connecticut Business Corporation Registry Search

The Connecticut Business Business Services Division keeps detailed information on entities incorporated in the state in its database. You can access the database to view information on entities such as Corporations, Limited Liability Companies and Limited Liability Partnerships.

Sole proprietorships and general partnerships are not registered with the Secretary of State as they are not individual business entities.  To find information about sole proprietorships and partnerships, go to the Town Clerk’s office where the business is located to look at the Trade Name registration records.

To search the database, you need to have at least one of the following information with you:

  • Name
  • Business ID
  • Filing Number
