Bulk CSLB license checker
Vetting a list of subs or vendors? Paste their license numbers or names and check license status, contractor bond, and workers' compensation for the whole list at once, each row flagged the same way a Prelien profile is. Export to CSV or a due-diligence PDF.
Paste a list of subs or vendors and we'll pull each one's license status, bond, workers' comp, and compliance flags from the public CSLB record.
Why general contractors bulk-check CSLB licenses
Before adding a subcontractor or vendor to a job, a prime contractor needs to know three things about each one: that the California contractor license is active, that the required contractor bond is on file, and that workers' compensation coverage is current. Those are the CSLB conditions that most often create downstream liability, an uninsured injury, an unbonded claim, an expired license that voids a contract. Confirming them one license at a time is slow and easy to skip under deadline. This checker resolves an entire vendor list in a single pass and links every row back to its full public record.
License status, bond, and workers' comp
For each entry you paste, the tool reports whether the license is active and unexpired, whether a contractor bond is currently on file, and whether workers' compensation is active, exempt, or missing. A contractor with no employees can lawfully file a workers' comp exemption, but if a sub will bring a crew onto your site, you want active coverage rather than an exemption, and the checker shows the difference at a glance.
What the compliance flags mean
Each contractor is summarized with the same model as a Prelien profile: Verified means no adverse conditions in the current record; Review flags something to look at before contracting, such as a license expiring soon or an exempt workers' comp status; and Alert marks a real compliance issue such as a cancelled bond or no active coverage. Because the logic mirrors the live contractor directory, a flagged row tells you exactly which condition to confirm before you sign.
Export to CSV or a due-diligence packet
Results download as a CSV for your own records, or as a multi-contractor due-diligence PDF, a summary table plus one factual section per contractor with its review flags, that you can save to a project file or hand to an owner. The data is an automated summary of public CSLB records, not a credit score or endorsement, so treat it as a vetting shortlist and confirm anything critical on the official CSLB record.
Frequently asked questions
What can I paste into the bulk checker?
A list of California CSLB license numbers, business names, or a mix of both — one per line, or comma-separated. Numeric entries are matched against the CSLB license number; text entries are matched against the business name.
Where does the data come from?
Every result is sourced from the public California Contractors State License Board (CSLB) record: license status, contractor bond, workers' compensation coverage, and classifications. It is an automated summary of public records, not a credit score, rating, or endorsement. Verify currency on the official CSLB website before contracting.
What do the compliance flags mean?
Each contractor is summarized using the same model as a Prelien profile: Verified (no adverse conditions in the current record), Review (something to look at before contracting, such as an expiring license or exempt workers' comp), or Alert (a compliance issue such as a cancelled bond or no active workers' comp).
Can I export the results?
Yes. Download a CSV of every row, or generate a multi-contractor due-diligence PDF packet with a summary table and one factual section per contractor — useful for vetting a whole sub list at once.
