Connecticut License Lookup: Verify a Business or Professional License on eLicense

Before you hire a contractor, buy from a licensed tradesperson, or work with a business that needs a state credential, confirm that the license is real, current, and held by the right name. A Connecticut license lookup runs through the state's eLicense system for most credentials, and through a few agency-specific systems for others. This guide shows you how to search, how to read what comes back, and what to do when a name does not appear.

This guide is informational only. It is not legal or tax advice. For a specific contract, dispute, or licensing question, talk with a qualified Connecticut attorney or CPA.

Connecticut has no general state business license

Connecticut does not issue one license that lets a business operate in general. Three different things get mixed up, and each one is checked in a different place:

• Entity registration. Forming an LLC or corporation with the Secretary of the State is a filing, not a license. An LLC files a Certificate of Organization for a $120 filing fee and then an Annual Report each year at $80. A corporation files its Certificate of Incorporation for $250 and then its Annual Report at $150. You can search registered entities and check name availability for free on the Business.CT.gov business search.
• Tax registration. A business selling taxable goods or services needs a Sales and Use Tax Permit from the Department of Revenue Services (DRS), which carries a $100 registration fee. It is a tax registration, not a license. See the DRS sales tax information page.
• Trade and industry licenses. These are the actual licenses, issued by the agency that regulates the field. The Department of Consumer Protection (DCP) handles many trades, the Department of Public Health (DPH) issues health-related credentials, the Insurance Department licenses insurance professionals, and the Department of Banking licenses certain financial businesses.

Because there is no general license, every lookup starts with one question: which agency issues the credential for this trade? Once you know the agency, you know where to search.

How to run a search on eLicense

The state's public license search lives at elicense.ct.gov. DCP describes it as a public, real-time system covering more than 800 license types regulated by state agencies. You can search by an individual's name or by a business name.

1. Open elicense.ct.gov and go to the public license search.
2. Enter the individual's name or the business name. If nothing matches, try variations: a middle initial dropped, "LLC" or "Inc." left off, or the name as it appeared on an older license.
3. Open the record that matches the name, town, and license type you expect. Two people can share a name, so compare the address before you trust the match.
4. Read the status, the expiry date, and any disciplinary entries. The next section explains each one.
5. Save a PDF or a dated screenshot of the record. Licenses change, and a lookup is only accurate for the day you ran it.

Reading the record: status, expiry, and disciplinary entries

Every record should answer four questions. Use this table as a checklist.

What to check	What it tells you	What to do if it looks wrong
Status	Whether the license is active or inactive. An inactive record is not a current license.	Do not rely on it. Ask the person to explain, then confirm with the issuing agency.
Expiry date	When the license must be renewed. A date that has passed means the license has lapsed unless a renewal is shown.	Ask for proof of renewal. If the record looks out of date, confirm with the agency.
Disciplinary entries	Any action the agency has recorded against the license.	Read the entry in full. Ask the person about it directly and confirm the outcome with the agency before you decide.
Name, address, and license type	Whether the record belongs to the person or business you are dealing with.	If the name or address does not match your contract or invoice, stop and confirm the legal name of the entity.

A clean status alone is not enough. A license can be active and still carry a disciplinary entry that matters to your decision, such as one tied to the kind of work you are hiring for.

When a name does not appear

Not every credential lives in eLicense. The Insurance Department, the Department of Banking, DESPP, and the DMV keep their own lookups or licensing systems. If a search comes back empty, do not conclude the person is unlicensed. Instead:

• Search again with name variations, and try the business name rather than the individual's name, or the reverse.
• Identify the agency that regulates the trade, then search that agency's own system.
• Ask for the license number and the issuing agency in writing, then check that number directly with the agency.
• Ask the agency to confirm the status in writing if the answer matters for a contract, a permit, or a payment.

Connecticut contractor license lookup: start with the DCP registration

A Connecticut contractor license lookup begins with DCP. Before you hire a home improvement contractor, search the contractor on eLicense and confirm that the DCP registration is current. Then check that the name on the registration matches the name on your contract, your invoice, and any insurance certificate the contractor gives you.

Ask the contractor to provide the registration details in writing, but verify them yourself. A copy from the contractor is a starting point, not proof.

Pre-hire checklist for home improvement work

1. Search the contractor's name on eLicense and confirm the DCP registration is current.
2. Match the legal name and address on the registration to the contract and invoice.
3. Read any disciplinary entries and ask the contractor about them before you sign.
4. If the contractor is an LLC or corporation, search the entity on Business.CT.gov to confirm it is registered.
5. Get a written contract before work starts, and keep your dated lookup record with it.
6. Confirm any local permit with the town or city. Zoning, health, and occupancy approvals are local, and a state search will not show them.

The Home Improvement Guaranty Fund

Connecticut's Home Improvement Guaranty Fund can pay up to $25,000 per contract after a court judgment. Payment depends on a judgment, so the fund is a remedy after a dispute reaches the court. It is not a substitute for checking the contractor before you sign. Confirm the claim process, the documents it requires, and the deadlines with DCP before you rely on it.

Business license lookup: records outside eLicense

If you are checking a business rather than an individual tradesperson, the most important records may not be on eLicense at all. A complete Connecticut business license lookup covers three places:

• Entity filings for LLCs and corporations are held by the Secretary of the State, Business Services Division. Search them on the Business.CT.gov business search. The same search shows whether a proposed name is available.
• Trade name certificates, sometimes called assumed name certificates, are filed with the town clerk of the Connecticut town where the business is primarily conducted, not with the state. The fee is $20, payable to the town clerk. Check with that clerk to confirm the certificate is on file.
• Sales and Use Tax Permits come from DRS. The permit must be displayed at each location, so ask to see it rather than assuming one exists.

Finding a business on one of these records does not prove it holds the trade license it needs. Check the license separately on eLicense or with the issuing agency.

Local approvals: towns, cities, and health offices

A state search will not show local approvals. Connecticut has no county government, so the local offices that matter are your town or city and, where it applies, a local health department or district. Zoning, health, and occupancy approvals may all apply to a business location. Call the town or city clerk, or the relevant local department, to confirm them.

Common mistakes to avoid

• Treating an entity registration on Business.CT.gov as proof that the business holds a trade license.
• Treating a Sales and Use Tax Permit as a license. It is a tax registration.
• Assuming a blank search means the person is unlicensed, without checking the issuing agency.
• Searching only the company name when the license is held in the owner's name, or the reverse.
• Saving no record of the check. A dated screenshot is your evidence if a dispute starts.
• Looking for a state business license. Connecticut does not issue a general one, and trade name certificates go to the town clerk.

Confirm these points with the agency

This guide does not settle every detail, so confirm the following directly before you rely on them:

• Which agency issues the credential for your specific trade, and whether that trade requires a DCP registration or another credential. Check with DCP or the relevant agency.
• How long disciplinary entries remain visible on eLicense. Check with DCP.
• How a Home Improvement Guaranty Fund claim is filed and what documentation it requires. Check with DCP.
• Whether a record missing from eLicense is held in another agency's system. Check with the issuing agency.

Next steps

Search the person or business on eLicense and save a dated record. If the credential does not appear, identify the issuing agency and search its system. For a business, check the entity on Business.CT.gov and the trade name with the town clerk. For a home improvement contractor, verify the DCP registration before you sign, and keep the Home Improvement Guaranty Fund in mind as a remedy that depends on a court judgment.
