California contractor license check: open the official record.
A California contractor license check should start at the official CSLB record. This page holds no contractor records; it turns a license number into a direct link to that license's own page on cslb.ca.gov — the Contractors State License Board's public system — and tells you what to read once it opens.

License and bond record check
Turn a California contractor license number into a direct link to that license's own CSLB record, and show the four lines to read once it opens.
How this works, and what it does not tell you
How this works
You type a California contractor license number. This page checks the shape of it in your browser - digits only, up to eight - and then builds the web address of that license's own page on cslb.ca.gov, the Contractors State License Board's public Check-A-License system. The address is shown to you in full before you open it, so you can see you are going to the state's own site. Nothing is fetched, copied or cached here and no network call is made: you read the live record yourself, as it stands on the day you read it. A business name has no equivalent link, because CSLB's name search runs inside its own form and produces no shareable web address, so this page sends you to that form with the name ready to paste.
What it does not tell you
A well-formed number is not a license. This page cannot tell you whether the number exists, who holds it, whether the status is active, or whether anything on the record changed since anyone last looked - only the CSLB record answers those, and only at the moment you open it. A license record is not an endorsement, a recommendation or a warranty of the work; it records what the state holds on file. The workers' compensation line on that record is not general liability insurance. Coastal SD Pros is not affiliated with CSLB, inspects nobody, and takes no payment to change what any tool on this site says.
JavaScript is off, so this page cannot build the link for you. Everything else below is readable as it stands, and the recipe is short: open cslb.ca.gov, choose Check-A-License, and enter the number — or type cslb.ca.gov/ followed by the license number straight into your address bar.
Nothing looked up yet. Both boxes are optional — the four lines below tell you what to read whichever way you reach the record.
Direct link to this license's CSLB record
Open the CSLB recordAddress it opens:
Before you read a word of it, check your address bar starts with cslb.ca.gov. A paid look-alike wrapped around the state's data is the oldest trick in this trade, and the state charges nothing for this.
If the record does not load, that is information. CSLB returns a page for numbers it holds. A number that returns nothing is a number to ask the contractor about, not a number to assume.
Direct link to a business-name search
CSLB does not publish one
The name search runs inside CSLB's own form and produces no shareable web address, so there is no honest link to give you. Checked Jul 25, 2026: the address such a link would need returns 404 Not Found. Rather than invent a link that appears to work, this tool hands you the three steps.
Open CSLB Check-A-License on cslb.ca.gov, choose Contractor Business Name, and paste the name.

The name to paste
A name search can return several licenses, or none. Several usually means related entities or a common trading name; none usually means the registered name differs from the name on the bid. Either way the next question is for the contractor: what licence number are you working under?
What to read once the record opens
1 · License status
Not on this page. It is on the CSLB record.
The status line sits at the top of the record. The line you are looking for reads this license is current and active. Expired, suspended, revoked or inactive all mean the same thing for your purposes: CSLB does not consider that company able to contract under that license right now. Status is the one line where there is no judgement call — you either read the active line or you do not.
Read it on CSLB Check-A-License, or on the record link this tool builds.

2 · Registered name, against who is actually bidding
Not on this page. It is on the CSLB record.
The record carries the registered business name, any DBA (doing business as), the address, and the people qualifying the license. Hold those against the name on the bid, the card and the van. A DBA is ordinary and appears on the record itself — on this site's Jul 6, 2026 check, one Oceanside company's license is registered to one corporate name and trades under another, and the record says so. A mismatch nobody can explain is the different thing, and it is worth one plain question before any money moves.

3 · Issue date, against how complex your job is
Not on this page. It is on the CSLB record.
The record shows the date CSLB issued the license. A recent issue date is a fact, not a fault — every company has a first year, and on a small, simple job it tells you almost nothing. It carries weight in one direction only: the bigger and more complex the job, the more a very new license is a reason to ask more questions, not fewer. How long has this crew worked together? What comparable job can you walk me past? Who is the qualifying individual on the license, and are they the person running my job?
Read the issue date on the record, next to the expiration date.

4 · Workers' compensation line
Not on this page. It is on the CSLB record.
Workers' compensation is not general liability insurance. This line says nothing about whether this business carries general liability cover.
The record shows either a workers' comp policy or an exemption filed with CSLB. An exemption states the licensee has told CSLB they have no employees. For a genuine one-person operation that is lawful and ordinary. It is worth a question when a crew shows up anyway. Whether that company carries general liability cover, and for how much, is a separate document you ask the contractor for — a certificate of insurance naming you — and it is not on the CSLB record at all.
Read the workers' comp section partway down the record.

A license record is not an endorsement
An active license means the state holds a current license on file for that number. It is not a review of anyone's work, not a recommendation, not a promise about your job, and not a statement that a company is a good fit for it. Companies with clean records do poor work and companies with plain records do excellent work; the record cannot separate them. It is the floor you check before you start looking, not the answer.

If there is no license number to check
California allows a narrow band of minor work to be done without a license, under conditions on the price of the job, whether it needs a permit, whether anyone is employed to help, and what the advertisement says. The conditions are specific, they have changed recently, and they are the kind of thing worth reading from the state rather than from a directory. Outside that band, a homeowner who hires an unlicensed person can end up treated as the employer, with the liabilities that attach to that.
Read CSLB's consumer pages on cslb.ca.gov for the current rules and thresholds. This page deliberately does not restate the dollar figures, because a stale number on a legal threshold is worse than no number.
