How to search for Connecticut business entities

Access the Connecticut business entity search to look up any registered business by name, entity number, or registered agent.

The search returns results immediately with all entity details visible on the results page. Navigate to the Connecticut Business Records Search portal and enter your business name in the search field.

The system covers both domestic (Connecticut-formed) and foreign (out-of-state but registered in Connecticut) entities, displaying comprehensive information for LLCs, corporations, partnerships, and nonprofits.
