Bulk Data & Images

In addition to our free business search, UCC search, and notary search, the Business Services Division provides free and subscription-based access to the data collected through the business registry, the UCC lien registry, and the notary registry.  The Office of the Secretary of the State is expanding its partnership with the Connecticut Data Collaborative to provide better access to our data.  To request additional data sets or to offer feedback on the data sets available, please email the Connecticut Data Collaborative at
