How to verify a Connecticut business end to end

  1. Search the exact legal name (or registration number) in the entity search and confirm the status shows active or in good standing.
  2. Match the registered name against the name on the contract or invoice; a different trade name should trace back to the same registered entity.
  3. Verify any trade or professional license in the licensing agency's own lookup, including status and expiration, not just that a number exists.
  4. For storefront or location-based work, confirm the local business license with the city or county clerk; it will not appear in statewide searches.
