How to search Connecticut business entities online

Connecticut's business entity search lives within the Business.CT.gov portal, a Salesforce-based platform operated by the Office of the Secretary of the State. The direct search URL is service.ct.gov/business/s/onlinebusinesssearch. Searching is open to the public; a free Business.CT.gov account is required only to file documents or order certificates.

An older URL path — /s/onlinebusiness — no longer works. The current path is /s/onlinebusinesssearch.

Entity types covered

The search covers all entity types registered with the Office of the Secretary of the State:

• Domestic and foreign LLCs
• Domestic and foreign stock corporations
• Domestic and foreign non-stock corporations (the form Connecticut uses for nonprofits)
• Limited partnerships and limited liability limited partnerships
• Limited liability partnerships
• Statutory trusts, cooperative associations, religious corporations, credit unions

How to search

The search form accepts three types of input: business name, the entity's ALEI (Connecticut's business entity identifier), or a filing number. An "exact name" toggle is available for name searches. The form includes a reCAPTCHA verification step. Advanced search options appear within the results interface after the initial query runs.

Entity detail page

Selecting an entity from search results opens a detail record showing the business name, ALEI, entity type, current status (active, dissolved, withdrawn, etc.), state of formation, formation or registration date, registered/statutory agent name and address, principal office address, and a list of filed documents.

Obtaining certificates and copies

Connecticut issues Certificates of Legal Existence — the state's equivalent of a good standing certificate. They are ordered through Business.CT.gov with a free account. Three formats exist for LLCs and corporations: an Express certificate (single-page status confirmation, $50), a Short-form certificate (includes all name changes, $50 for LLCs or $80 for corporations), and a Long-form certificate (full domestic entities only, $100–$120 depending on entity type). Long-form certificates cannot be expedited. Verifying a previously issued certificate is free at service.ct.gov — Verify Certificate.

Separate searches for trademarks and UCC

Trademark and service mark searches use a dedicated tool at service.ct.gov/business/s/trade-and-service-marks-search. UCC lien searches are at service.ct.gov/business/s/onlineenquiry. Both are accessible without an account.
