Connecticut Business Registry: New Registrations with Email, NAICS & Principals

Pulls newly registered Connecticut businesses from the Secretary of the State business registry on data.ct.gov into clean JSON lead records: business name, entity type, status, registration date, business email address, NAICS code, annual report due date, business and mailing address, formation jurisdiction, and the registry's woman, veteran, minority, disability and LGBTQI-owned survey flags. Optionally joins each business to its principals (officers, directors, members, managers) and its statutory agent (with phone and email where published).

Connecticut's public registry carries a business email on nearly every new entity: 5,142 of the 5,143 Active businesses registered between 2026-07-23 and 2026-08-23 have one, and 5,073 (98.6%) carry a NAICS code. No scraping of the business.ct.gov website, no guessing, no enrichment: every field is exactly what the registry publishes.

Who uses this data

• B2B lead generation and local marketing agencies reaching new Connecticut businesses in their first weeks, by industry (NAICS) and town, with a published email instead of a guessed one.
• Supplier diversity and procurement programs finding newly formed woman-, veteran-, minority-, disability- and LGBTQI-owned businesses from the registry's own survey flags.
• Annual report, registered agent and compliance vendors working the annualReportDueDate field and the statutory agent of record.
• Banks, insurers, payroll and POS vendors onboarding new LLCs and corporations by county.
• Researchers and journalists tracking business formation in Connecticut by industry, town and month.

}

Every item also carries subStatus, beganTransactingInCtDate, organizationMeetingDate, dissolutionDate, administrativeDissolutionReason, formationPlace, formationCountry, nameInFormationJurisdiction, surveyEmail, naicsSubCode, recordsAddress, officeInJurisdictionAddress, mailingInJurisdictionAddress, mailingInternationalAddress, totalAuthorizedShares and sourceDatasetId. Fields the registry left blank are null, never invented. Dates are ISO 8601 (YYYY-MM-DD). businessCounty is derived from the business address town through the state's own town-to-county crosswalk and is null for out-of-state addresses. A run summary (row counts, filters applied, malformed rows skipped, whether the charge limit stopped the run) is saved under the OUTPUT key.

Input

Field	Type	Default	What it does
registeredFrom	date	7 days ago	Registered (formed, or registered in CT for foreign entities) on or after this date.
registeredTo	date	none	Registered on or before this date. Set alone, it removes the 7-day default.
status	select	Active	Active, any, Forfeited, Dissolved, Withdrawn, Revoked, Cancelled, Merged, Expired, Reserved, Expired Reservation.
businessType	select	any	LLC, Stock, Non-Stock, Limited Partnership, LLP, Religious, Statutory Trust, Special Chartered, General Partnerships, B Corp.
naicsPrefix	string	none	2 to 6 digits; keeps NAICS codes starting with them (23 construction, 54 professional services, 72 food and lodging).
county	select	any	One of the 8 Connecticut counties, matched through the business address town (Connecticut addresses only).
town	string	none	Business address city, case-insensitive exact match, Connecticut addresses only.
nameContains	string	none	Case-insensitive substring of the business name.
womanOwned, veteranOwned, minorityOwned, disabilityOwned, lgbtqiOwned	boolean	false	Keep only businesses that answered yes on the registry survey.
includePrincipals	boolean	false	Attach principals from the Principals dataset (queried in batches of 100 entities, paged as needed).
includeAgent	boolean	false	Attach agents from the Agents dataset (queried in batches of 100 entities, paged as needed).
maxResults	integer	100	Records to deliver and your cost cap (1 to 50,000).
includeRaw	boolean	false	Attach the source rows under raw.

All filters run on data.ct.gov, so a narrow query is as fast as a broad one and you only pay for what is delivered.

Example inputs

New construction businesses in Hartford County this quarter, with owners and agent:

{ "registeredFrom": "2026-07-01", "county": "Hartford", "naicsPrefix": "23", "includePrincipals": true, "includeAgent": true, "maxResults": 500 }

Woman-owned businesses formed in Stamford this year:

{ "registeredFrom": "2026-01-01", "town": "Stamford", "womanOwned": true, "maxResults": 1000 }

Every status, for a name check:

{ "registeredTo": "2026-08-31", "status": "any", "nameContains": "harbor point", "maxResults": 50 }

Pricing

$0.003 per delivered record. Nothing else is charged: a filter that matches nothing costs nothing, and maxResults is a hard cap.

Data source, refresh and licence

• Agency: Connecticut Secretary of the State, Business Services Division, published through the Connecticut Open Data Portal (data.ct.gov).
• Datasets: Connecticut Business Registry - Business Master (n7gp-d28j, 1,293,406 entities, 457,546 of them Active, on 2026-08-23); Principals (ka36-64k6, 1,782,672 rows); Agents (qh2m-n44y, 1,308,139 rows, of which 728,074 carry an agent email and 607,744 a phone).
• Refresh: the portal lists the update frequency as Daily; on 2026-08-23 the Business Master was refreshed at 08:30 UTC and carried registrations dated that same day. 1,136 Active businesses carried a registration date of 2026-08-16 or later on 2026-08-23.
• Licence: the Business Master dataset's portal metadata states licence "Public Domain" and attribution "Secretary of the State". The Principals and Agents datasets carry the same attribution and no licence field in their metadata.
• Attribution on every record: Secretary of the State.
• Politeness: sequential requests, 1 second apart (the host's published Crawl-delay), no app token, a descriptive User-Agent.

Not affiliated with or endorsed by the Connecticut Secretary of the State or the Connecticut Open Data Portal.

Limitations

• Emails, phones and names are delivered only when the registry publishes them. The actor never looks anything up elsewhere and never fills gaps.
• The registry has no county column and its geolocation column is empty on recent rows, so county filtering keys on the business address town; a business whose address city is misspelled or out of state will not match a county filter.
• registrationDate is the formation date for domestic entities and the Connecticut registration date for foreign ones, exactly as the registry defines it.
• A row missing a required field (id, name, type, status, account number, registration date) or with an unparseable date is skipped and counted in the run summary, never delivered.
• If the source stops serving data, shrinks implausibly, or changes its columns, the run fails with a clear message and nothing is charged. The default run also fails rather than reporting zero new businesses.

FAQ

How do I get a list of new businesses in Connecticut?

Run with the default input: the 100 Active businesses registered in the last 7 days. Raise maxResults or widen registeredFrom for more.

Does the Connecticut business registry include email addresses?

Yes. The Business Master dataset publishes business_email_address, present on 5,142 of the 5,143 Active businesses registered between 2026-07-23 and 2026-08-23. It is delivered as email, unchanged.

Can I search Connecticut businesses by NAICS code?

Yes, with naicsPrefix. The registry publishes NAICS either as a bare code or as "Description (code)"; both forms are matched and split into naicsCode and naicsDescription.

How do I find woman-owned or minority-owned businesses in Connecticut?

Set womanOwned, minorityOwned, veteranOwned, disabilityOwned or lgbtqiOwned to true. These are the registry's own survey answers, delivered under ownership on every record.

Who are the owners or officers of a Connecticut LLC?

Set includePrincipals to true. Principals (officers, directors, members, managers, partners) are joined from the Principals dataset on the entity id, with the designation the registry recorded.

How do I look up a Connecticut registered agent?

Set includeAgent to true. The statutory agent of record is joined from the Agents dataset with type (individual or business), phone and email where published.
