What you get with a Connecticut lookup
- Connecticut SOS entity record — name, status, entity type, formation date, registered agent + address, principal office, and officers/managers where the state exposes them.
- USDOT / FMCSA carrier verification — for trucking deals, we pull the carrier's authority status, MC#, fleet size and MCS-150 history, plus the FMCSA SAFER snapshot. Auto-matched to the SOS legal name when applicable.
- OFAC SDN screening — optional: add it to your search to check the company name against the Treasury sanctions list.
- DBA / Fictitious Name finder — a separate tool that points you to the county/town clerk's own search (or the statewide registry) where a DBA is filed in Connecticut.
- One merged PDF — cover sheet + SOS record + USDOT snapshot + supporting docs, all in a credit-file-ready packet.
How Connecticut files business entities
Connecticut publishes its entire business registry as open data on data.ct.gov, including a separate Principals dataset that lists owners by name AND residence address. That's one of the strongest free owner-graph signals available in any state.

How DBAs work in Connecticut
Connecticut Trade Names (DBAs) file at the city or town clerk — Connecticut abolished county government in 1960, so there is no county-level filing layer. With 169 municipalities, there is no central state DBA registry; the open-data business-master file covers entities only.
Credit-underwriting gotchas in Connecticut
Connecticut LLCs and LLPs owe a flat $80 annual report fee. Missing the annual report leads to administrative dissolution within roughly a year — Connecticut moves faster on dissolution than most Northeast states. The 'Principals' dataset on data.ct.gov sometimes lags the entity-master file by a few weeks, so a brand-new principal may not appear on the open data immediately.
Practical Connecticut reference
Filing fees: $120 LLC formation fee + $80 annual report
Officer visibility: Principal data including home addresses is published on data.ct.gov as open data — a stronger signal than most states publish on their public portal. The Connecticut search page also shows registered-agent details inline.
