Find Connecticut Business Records

This guide helps you use the official Connecticut Business Lookup to search LLCs, corporations, partnerships, statutory trusts, trade names, trademarks, UCC records, certificates, copies, annual reports, and business filing paths.

Use it before you file an annual report, order a certificate, verify a vendor, check a business name, update a registered agent, or respond to a dissolution/revocation notice.

🔎 Free public lookup 🏢 LLC & corporation 📄 Filing history 🧾 Certificates and copies 📆 Annual reports 🛡️ Registered agent

Fast answer: Use the official Connecticut Business Lookup on Business.CT.gov to search business records on file with the State of Connecticut. The same Business.CT.gov menu also links to Trade Name, Trademark, and UCC Lien searches.

Best practical workflow: search the business name broadly → open the matching record → confirm legal name, status, business type and filing history → save the record details → use annual report, certificate, copy, name-change or agent-update services only after confirming the correct entity.

Important difference: a Connecticut business entity record is not the same as a local trade name, professional license, tax account, permit, or fraud investigation record. Use the correct agency when your question goes beyond Secretary of the State filings.

Image description: this user-help visual reference shows the Connecticut Business Lookup or Business Records Search screen where users can search business records on file with the State of Connecticut. It is not a claim that this website is the official Connecticut government website.

Search with the strongest words first

Use the unique part of the name. Try without LLC, Inc, Corporation, Company, punctuation, apostrophes, and The if the exact name does not appear.

Open close matches

Do not stop at the first result. Compare legal name, business type, status, principal address, agent details, and filing history.

Check filing history

The filing history is useful for annual reports, amendments, address updates, agent changes, dissolutions, revocations, certificates, and copies.

Look for recent notices

If you received a Notice of Intent to Dissolve/Revoke or a Certificate of Dissolution/Revocation, Business.CT.gov says the letter will be located under the most recent filing history.

Use the correct follow-up service

After confirming the record, choose annual report, certificate, copies, agent update, business address change, business name change, or help ticket based on your actual need.

Save proof before paying

Save the business name, status, filing date, record page, and filing history. If you need official proof, use Certificate of Legal Existence or certified copies.

How to Read a Connecticut Business Record Without Wrong Assumptions

A business record can answer many questions, but it is not proof of everything. Use these fields carefully.

🏷️

Legal name

Use exact legal name for filing, certificates, bank documents, and official transactions. Trade names may be separate.

🏢

Business type

LLC, stock corporation, non-stock corporation, LLP, LP, statutory trust, and foreign entities can have different fees and filings.

🚦

Status

Status helps you understand whether the entity appears active, dissolved, revoked, or administratively affected.

🛡️

Registered agent

A registered agent receives and forwards legal and official correspondence on behalf of a business.

📄

Filing history

Use filing history to find reports, amendments, copies, notices, name changes, agent changes, and dissolution/revocation clues.

📍

Address data

Address information may be mailing, principal, business, agent, or filing-related. It is not always a customer-facing location.

Best verification habit: For serious use, save the record page, note the search date, compare filing history, and order a certificate or certified copy only when a bank, vendor, contract, or agency requires official proof.

Trade Names, Trademarks and UCC Records Do Not Mix Them Up

Many users search the wrong database. Connecticut separates entity records, trade names, trademarks, and UCC lien records.

🏷️

Trade names

Use trade name search when a business uses a public operating name different from the legal business or owner name.

Search trade names
™️

Trademarks

Use trademark search for Connecticut trade or service mark records. This does not replace federal trademark or entity search.

Search trademarks
🔐

UCC liens

Use UCC search for financing statements, lien-related records, and secured transaction research.

Search UCC liens
Insider tip: If you are checking whether a business name is available, search entity records, trade names, trademarks, and web/domain usage separately. No single search proves everything.

Non-filing risk

Use certificates and copies only after confirming the exact business record. A certificate or certified copy is usually needed for banks, transactions, financing, vendors, or legal paperwork.

🧾

Certificate of Legal Existence

Common Connecticut Business Search Problems and Fast Fixes

If you cannot find the record, change the search approach before assuming the business does not exist.

No results found

Remove LLC, Inc, Corporation, punctuation, apostrophes, and The. Search the strongest unique words only.

🔁

Too many results

Add one more unique word, compare legal name and filing history, then use status and agent details to identify the right entity.

🏷️

Trade name confusion

If the public name does not match entity search, try Trade Name Search because the business may operate under a different name.

🧾

Certificate confusion

Certificate of Legal Existence is not the same as a plain search result. Use it when official proof is required.

🛡️

Agent issue

Registered agent information can cause filing problems. Update or confirm agent details before filing annual reports if the system flags it.

⚠️

Third-party filing letters

Be careful with companies offering to file your annual report for a fee. Use official Business.CT.gov pages whenever possible.
