DrillerDB tracks 1,497 active well-driller license records from 690 companies in California. These are the verified licenses we track, not a complete roster of every licensed driller in the state.
What California requires of well drillers
California regulates well construction and driller licensing under DWR Bulletin 74. Before you hire, confirm a driller's current license and standing with the state directly - a license can lapse or change status between our checks.

California well driller license lookup: FAQ
- How do I verify a well driller's license in California?
- Enter the driller or company name above. We search verified California well-driller license records and show the license status, type, and when we last verified it, with a link to CA DWR - plus that driller's profile in our directory.
- Does "no record found" mean a driller isn't licensed in California?
- No. Our index does not cover every driller in California, so a missing record is never proof that someone is unlicensed. Check CA DWR directly, and consider the verified drillers we do track nearby.
- Where does the California license data come from?
- From public license records published by CA DWR, verified per row on the dates shown. DrillerDB is an index; the issuing state board is the authoritative source of record.
