What is a contractor license lookup?

By Youssef Hodaigui, Mindflow Marketing · Last reviewed November 1, 2026

A contractor license lookup is a licensing board's public online search that shows whether a contractor holds a license, what kind, whether it's active, and often its complaint or discipline history. Each state runs its own, and some trades are licensed by a separate board or only by a city or county, so there's no single national lookup.

Homeowners use it to check you before they sign. Search tools and AI answers use the same public records to confirm who you are, so what your license record says, and the name it's under, matters for marketing as well as compliance.

01

Where do homeowners look up a contractor license?

On the state board's website, and which board depends on the state and the trade. California's Contractors State License Board runs one statewide contractor search. Texas splits it: plumbers have their own board, and the main state search lists no general contractor or roofer license. Florida runs one portal across many professions. Three examples, read November 1, 2026:

StateWhere to lookWhat it covers
CaliforniaCSLB "Check a License"Contractor licenses and home improvement salesperson registrations, searchable by number, business name or person, "including complaint disclosure"
TexasTDLR license search; Texas State Board of Plumbing Examiners for plumbersTDLR lists types such as Air Conditioning Contractors, Electricians and Mold Remediation Contractors (active licenses only); no general contractor or roofer type
FloridaDBPR licensing portalSearch by name, license number, city or county, or license type

Thresholds differ too. In California, a state law effective January 1, 2025 raised the job size that needs a license "from $500 to $1,000," for small jobs with no employees and no permits, according to CSLB.

02

Do you have to show your license number in ads?

In some states, yes. California Business and Professions Code § 7030.5 says "Every person licensed pursuant to this chapter shall include his license number in" contracts, bids and the advertising the registrar specifies. Florida's § 489.119(5)(b) says the number "shall appear in each offer of services, business proposal, bid, contract, or advertisement, regardless of medium, as defined by board rule."

In Florida that can reach your website and online ads, and the same section requires the number on vehicles lettered with your business name; the board's rule sets the details. Rules vary by state, trade and city, and change, so check with your licensing board. This is a summary for owners, not legal advice. Even where it isn't required, showing your number on your site makes the lookup easy for a customer, which is the point.

03

Why can't customers find your license?

Usually because the name they search isn't the name on the license. Licenses are often issued to an LLC or a qualifying person, while customers know your trade name. CSLB's own search tips show how fussy name searches are: "type the last name first" for names like "John Smith Construction," leave out "The," and skip commas and periods.

Three fixes cover most cases. Put your license number on your website, near your business name. Make sure your legal name and trade name are both visible, for example in your footer, so a customer can connect them. And keep your board record's address and business name current when you move or restructure, because an outdated record looks like a different company.

04

Why does the license record matter for marketing?

Because AI answers cite the records customers check. In our study, government or licensing sites were cited in most ChatGPT answers about named contractors in all eight trades of our main study, from 1,095 of 1,482 for garage doors to 1,382 of 1,500 for pest control, with state sites such as ca.gov and myfloridalicense.com among them (what ChatGPT checks).

Yet in our contractor website study, only 2,375 of 4,433 homepages said "licensed" at all. That's the OpenAI API with web search in October 2026, and homepages saved the same month. A license number on your site, matching the record an answer finds, connects the two. The Google Verified screening for Local Services Ads checks state licenses for some trades too.
