Verification guide

How to verify a California geologist license

Content reviewed

Match the professional's legal name and license number to the directory record, then open California Board for Professional Engineers, Land Surveyors, and Geologists's official record to confirm that the geologist license is current in California.

What to check in the license record

  • The name and license number match the plans, seal, proposal, or contract you are reviewing.
  • The credential is active for the correct profession and issuing jurisdiction.
  • The expiration or renewal date covers the date the professional performed the work.
  • Any limitations, disciplinary actions, or board orders have been reviewed.

California licensing rules

License number format
The Board's own license-lookup instructions state that a license number is entered as digits only: "Enter NUMBERS ONLY without any leading zeroes. Do not enter alphabetical characters." The same license number can be shared across multiple license types, so the license type shown alongside the number (not the number itself) distinguishes the discipline. Source
