Bulk Data & Images

Updated December 2022


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, allowing filtering and extracting of the search results. Note, the extract feature currently limits exports to 1,000 rows. If the data you are extracting has more than 1,000 results, please see below for how to extract that data.  
  • 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 Data Dashboard - Free

We use the State Open Data Portal (data.ct.gov) to visualize commonly-requested data. These visualizations will grow and improve over time. Please submit a ticket if you have a comment on the visualization or would like to see one that is not offered. 

The current visualizations show:

  • Business formations and registrations by month for the past 18 months
  • All active businesses by business type and citizenship
  • All businesses formed last month by type and citizenship
  • Map of businesses with Connecticut business addresses
  • Active businesses grouped by North American Industry Code standards (NAICS)

Advanced Data Filtering Tips

The data we publish is the complete Connecticut Business Registry dataset. Here are some tips on filtering it to find what you are looking for. 

Finding businesses registered over a time period (e.g., one month).  

1. Go to the business master data
2. Choose "filter"
3. Choose "Date_Registration" and the filter "in between"
4. Enter the dates you want to search between. The below example shows all businesses formed in the month of November 2022.

Business Entity Database - Free

We no longer charge for access to the business registry database extract. The extract will be posted on the state‚Äôs 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 bsd@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.  

1. Business Master (Account Object)

This is the master data object for the business details information contained in the Connecticut Business Registry System.  

2. Agent Details Object

This is the agent details object related to the statutory agents appointed by the businesses reflected on the business master object.  

3. Business Principal Details Object

This is the principal details object related to the principals (officers/directors/members/partners) reported by the businesses reflected on the business master object.

4. Business Filing Details Object
