Verify an electrician licence in California

Check an electrician's licence in California by number or by business name and get one normalized JSON record back, sourced from the Contractors State License Board (CSLB). The Contractors State License Board extract holds 34,006 records under these classifications as of 2026-08-05.

Which CA classifications count as electricians

• C-10 — Electrical Contractor 29,071 records
• C-7 — Low Voltage Systems Contractor 4,935 records

A record's classifications array carries these codes, so you can tell a licence that covers the work from one that merely exists.

Run it

curl "https://contractor-license-verification2.p.rapidapi.com/v1/licenses/CA/1000010" \
  -H "X-RapidAPI-Key: YOUR_KEY" \
  -H "X-RapidAPI-Host: contractor-license-verification2.p.rapidapi.com"

1000010 is a real CA licence (MICHAEL ALLAN CANNON) in this trade, so that call works as written.

Before you rely on it

C-10 is the electrical contractor licence. C-7 is low voltage — alarms, data, sound — and does not authorise line-voltage work. CSLB also certifies individual electricians separately from the contractor licence, and that certification is not in the CSLB extract, so this API verifies the business licence rather than the individual electrician's card.

What Contractors State License Board does not publish

• Disciplinary actions
• General liability insurance
