The Connecticut Business Business Services Division keeps detailed information on businesses 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 (which is different from the Employer Identification Number assigned by the IRS)

Step 2 – Type in either the Business Name, Business ID, or Filing Number. It’s not mandatory to key in all the fields, but if you fill in every detail, you will get more specific results.

If you want a wild card search, you can put an asterisk symbol followed by the Business Name (for example, *Duracell). All the business entities named “Duracell” will then appear.

Assuming you’ll conduct the search based on Name, let’s type in “Odyssey Toys“.

  • Business Address (PO Boxes are not allowed)
  • Mailing Address
  • Date of Registration
  • Connecticut Annual Report Due Date
  • Business Type (Limited Liability Company, Corporation, etc.)
  • Business Status

Statutory Agent

In Connecticut, a Statutory Agent (commonly referred to as a Registered Agent) is a legal requirement 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 files as the entity’s Statutory Agent.  When they file, their home address is often used (PO Boxes aren’t allowed), and their name and address are now a public record that can be looked up by anyone.  If that is a concern, consider looking into a Registered Agent service.

Business Licenses

Business name registration is different from business licensing in Connecticut.  The Connecticut State Department of Consumer Protection has more information regarding a business license.
