California Licensed Electrical Contractors
U.S. Location Dataset // 23,618

This is the complete licensed universe of electrical contractors in California, not a directory of the ones who chose to be listed: every active license the California Contractors State License Board publishes in its public extract, reduced to one row per licensed firm or individual at an address. 23,618 records. Classifications in the file: C10 (17,277), B | C10 (3,103), C-7 | C10 (557), A | B | C10 (338). 1,072 licensees list an out-of-state address (contractors licensed in California but based elsewhere); the state column identifies them so they are one filter to drop. Each record carries the state license number, so it joins cleanly to permit data, insurance certificates and other state files, and the expiration date, so you can target renewals. Buyers use it for distributor and manufacturer territory planning, dealer-program recruitment, insurance and financing prospecting, and roll-up sourcing in a fragmented trade. Association lists such as our ACCA member dataset cover the engaged slice; this covers everyone the state allows to pull a permit. Refreshed weekly from the board's extract.

All 23,618 records, as published — the complete set rather than a sample. That matters most for coverage and gap questions: put together the same list from partial searches and every location you miss reads as a gap that is not there, so the answer is wrong rather than merely late. Assembling the U.S.-wide coverage by hand also means one query per area against sources that cap what they return per search.
