In order to practice social distancing and slow the spread of the novel coronavirus (COVID-19), public access to our building, 165 Capitol Avenue, will be restricted. Although in-person interactions will be limited, our office staff will be available via email as normal. For the Business Services Division email CRD@ct.gov and for the Legislative & Elections Administration Division email LEAD@ct.gov. We apologize for the inconvenience and hope to return to normal business as soon as the immediate threat to public health has subsided.

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 info@ctdata.org.  

Business Starts - Free

This data set provides new business entity formations over the preceding month.  This data set is no longer provided as a subscription service and is now provided free of charge through our partnership with the Connecticut Data Collaborative.  Select "Download Data by Month" to view the available data sets.

Business Starts/Stops Aggregate Data - Free

The Connecticut Data Collaborative provides a starts/stops tool to view business formation/registration and dissolution/withdrawal information over time.  The data may be freely downloaded.  

Business Entity Database - Subscription $3,000/year

This is a fixed-length extract of the business entity database tables.  Subscribers will be provided the data via a link to a Sharepoint site where the data is located.  Please note that these are raw extracts of our business registry data and using the files requires substantial understanding of database structures and formatting.  Subscribers who currently receive this information via FTP will continue to receive the data through that method.  

UCC Images - Subscription - $1,000/year

Portable Digital Files (PDF) of each UCC volume created and finished during the preceding month.  Subscribers are provided a link to a Sharepoint site containing the UCC images.  

New Notary Data - Free

Using the eLicense System, users may search for individual notary records or download a roster of all active notaries or all inactive notaries. 

UCC Data - Free

This data set provides all active UCC liens and other liens filed with our office.  "Active" liens are liens that have not lapsed (expired).  Due to customer demand, this data set is now available for free on the state's Open Data Portal.  Data on the Open Data portal may be freely downloaded or accessed through API.  This data set is updated nightly.  The panel below provides a preview of the data available and a direct link to the data set.  For feedback or questions about this data set, please email our office directly at crd@ct.gov.
