Supported state license databases

A contractor license lookup verifies that a subcontractor holds a current, active license issued by the relevant state licensing board — TDLR in Texas, DBPR in Florida, CSLB in California, L&I in Washington, the Building Codes Division in Oregon, IDFPR in Illinois, or DORA in Colorado. TrackMyVendor pulls from official state databases so every result reflects current government records.

Track a license from any state

The lookup above reads official state databases, so it can only search the states we import. Tracking has no such boundary: add a license from any state, for any trade, with its number and expiration date, and TrackMyVendor watches the date and alerts you before it lapses — alongside every COI and W-9 on your roster, which were never state-scoped at all.

What contractor license status means

When you look up a license, you'll see a status field. Here's what each value means — and why it matters before you put a sub on a job. For the full reference, see our contractor license status guide, or walk through how to verify a contractor license step by step.

Active

The license is current, has not expired, and the holder is in good standing with the issuing board. This is the status you need to see before a sub starts work. Active alone does not guarantee insurance or bond coverage — always verify COIs separately, ideally with COI tracking software that monitors certificate expirations alongside license status.

Expired

The license renewal deadline has passed. An expired license typically means the contractor is no longer legally authorized to perform licensed work. Work performed under an expired license can expose your organization to liability and may void your insurance coverage.

Suspended

The board has temporarily revoked authorization to work — commonly due to a lapsed bond, lapsed workers' comp insurance, unpaid fees, or a disciplinary action. A suspended license is different from an expired one: the license period may not be over, but the contractor cannot legally work. Do not allow a suspended-license sub on-site.

Inactive

The licensee has voluntarily placed the license on inactive status. They may not legally perform licensed contracting work while inactive. This is common between projects or during retirement from active contracting. Verify with the sub before engaging them for any licensed trade work.

Single lookup vs. ongoing monitoring

A one-off lookup answers the question "is this sub licensed right now?" But for general contractors and property managers with a roster of vendors, a snapshot is not enough — license verification software turns that single check into automatic daily monitoring across every sub.

Contractor license lookup FAQ

Is contractor license lookup free?

Yes — single license lookups on TrackMyVendor are completely free with no account required. You can verify status, expiration date, and license holder for any Texas (TDLR), Florida (DBPR), California (CSLB), Washington (L&I), Oregon (BCD), Illinois (IDFPR), or Colorado (DORA) contractor license at no cost. For ongoing monitoring and alerts across a full roster, a free account lets you track up to 25 vendors.

What is a TDLR license in Texas?

TDLR stands for the Texas Department of Licensing and Regulation. TDLR issues licenses for dozens of trades in Texas including HVAC technicians, plumbers, electricians (TECL), irrigators, and many others. Before hiring any Texas contractor in a licensed trade, you should verify their TDLR license number is active and not suspended or expired.

What is the DBPR in Florida?

DBPR stands for the Florida Department of Business and Professional Regulation. The DBPR licenses and regulates Florida contractors including Certified General Contractors (CGC), Certified Building Contractors (CBC), Certified Roofing Contractors (CCC), and many other specialty trades. You can look up any Florida contractor's DBPR license number to verify current standing.

What is a C-10 California contractor license?

A C-10 license is a specialty electrical contractor license issued by the California Contractors State License Board (CSLB). It authorizes a contractor to install, construct, maintain, repair, and alter electrical wiring, fixtures, and equipment. C-10 is one of the most common specialty contractor licenses in California. You can verify any sub's C-10 status using the lookup widget on this page.

What is an L&I contractor registration in Washington?

L&I stands for Washington State Department of Labor & Industries. L&I issues contractor registrations for general construction work (required for projects over $500 in labor and materials) and separate licenses for specialty trades such as electrical (EL), plumbing (PL), and elevator contractors (LC). Washington uses the term "registration" for general contractors and "license" for specialty trades — both are issued by L&I and both can be verified using TrackMyVendor's free Washington license lookup.

What is a CCB license in Oregon?

CCB stands for the Oregon Construction Contractors Board. Most contractors performing construction work on residential or commercial structures in Oregon must hold a valid CCB license. The CCB issues several license types based on scope: Residential General, Residential Specialty, Commercial General, Commercial Specialty, and others. CCB licensees must also maintain a surety bond (set by endorsement, from $15,000 to $80,000) and general liability insurance. TrackMyVendor's Oregon license lookup searches the CCB's active contractor licenses and the Building Codes Division's electrical, plumbing, boiler and elevator licenses; confirm a suspension on the CCB's own search.

How do I look up a contractor license by name?

Select the state, then enter the business name or the license holder’s last name instead of a number and the lookup returns every matching license in that state, with status and expiration for each. Name search matches from the start of the holder name as it is recorded by the state board, so start with the first word of the business name (for example “South Coast” rather than “Construction”). Pick a result to see its full record. If you already have the license number, enter it instead for a single exact match.

What's the difference between a lookup and ongoing monitoring?

A lookup gives you the current status of a license at a single point in time — useful for vetting a new sub before hiring. Ongoing monitoring means TrackMyVendor continuously checks your entire vendor roster against state databases and alerts you before any license expires or is suspended. For contractors and property managers with multiple vendors, ongoing monitoring eliminates the risk of a license lapsing unnoticed mid-project.
