A dash means the board does not publish that field. The Actor never guesses one: a column the board leaves empty comes out empty.
What you can look up in California
- Look up a license by number or business name: status, type, expiry, address, phone. In detail mode, a number that is expired, inactive, cancelled, suspended or revoked comes back saying so, read live from the board; a number the board does not know comes back "not found", free. A name search reads the bulk file, which carries active licenses only.
- Export a whole trade: every contractor the board licenses in it, with
expiringWithinDaysfor renewals coming up andissuedWithinDaysfor licenses issued this month. - Full detail per license, straight from the CSLB page: bond company, number and amount, workers' compensation carrier and policy, every classification, entity type and today's status; other CSLB sections passed through as text.
