Bulk Data & Images

Updated October 2021


Our bulk data and image policy has changed due to the move of the business registry and ucc registry to business.ct.gov. 

  • The business records search now contains an advanced search feature to search by business name, city, principal, and agent and allows filtering and extracting of the search results.
  • The UCC Lien Search also allows for extracting of search results.
  • The Notary Public Search remains on the state eLicensing platform.  

Below are the data sets offered by the Business Services Division.  

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 - Free

We no longer charge for access to the business registry database extract.  The extract will be posted on the state’s data portal at data.ct.gov as five data sets.  The Business Master (Account Object) data set contains the primary information collected for each entity on the Connecticut Business Registry System.  The Agent Details, Principal Details, Business Filing Details, and Business Name History object data sets are intended to be subsidiary objects of the Business Master (Account Object) data set.  Please see the data sets for more information about the structure and data definitions. Please send questions or requests for additional fields or data definitions to crd@ct.gov.  

These data sets will be updated nightly and each set contains the extract date/time. 

Data.ct.gov will be the only source for this data and we will no longer be posting to Sharepoint or FTP.
