About San Mateo County Criminal History

San Mateo County records are divided among the Sheriff's Criminal Records Bureau, Superior Court, California Department of Justice, California Department of Corrections and Rehabilitation, and California Megan's Law Website. We organize those official routes so a reader can identify the right portal, counter, address, or telephone contact without treating separate records as one database.

Why We Built This Site

California access depends on the kind of record sought. The Sheriff's Office keeps its reports and county booking material, while San Mateo County Superior Court holds filed charges and dispositions. California DOJ maintains state summary criminal history, but offers no public name search for rap sheets. CDCR tracks state custody, and Megan's Law is a limited public-safety registry. This resource brings the verified contacts, request steps, portal limits, and available fees into a clear local path.

What You Will Find Here

  • Agency contacts: where San Mateo County and California record custodians can be reached
  • Record guides: how court case records can be found and read locally
  • Official review routes: how fingerprint-based self-review works through California DOJ
  • Record relief: where California expungement and sealing requests begin

What We Cannot Do

This is a privately run reference site, with no tie to a California court, law-enforcement agency, or state office. Its limits are straightforward:

  • We cannot run an official background check or pull a criminal record for anyone
  • We cannot file expungement petitions, records requests, or any other paperwork on your behalf
  • We cannot issue certified copies of any criminal record, court document, or rap sheet
  • We cannot give legal advice or explain how a specific charge or case applies to you
  • We cannot guarantee that every phone number, fee, or address listed on this site is current right now

An official copy must come from its custodian, such as San Mateo County Superior Court, the Sheriff's Office, or California DOJ.

Search Partners

Outside providers power some search boxes. They control their results, prices, and service terms. A paid signup reached through one of those tools may produce a referral fee that supports site operations. We do not set the provider's charges or decide what its search returns.
