California Death Records

San Mateo County Death Records

San Mateo County, situated between San Francisco and Silicon Valley, transitioned from a suburban bedroom community to a tech hub in its own right during the period covered by our death records. The county's coastal communities and established neighborhoods attracted retirees, while its proximity to San Francisco General Hospital and Stanford Hospital means some death records are for individuals from neighboring counties.

How to Get a San Mateo County Death Certificate

Death certificates for deaths that occurred in San Mateo County can be obtained from the county clerk's office or from the California Department of Public Health (CDPH). The county office is typically faster for in-person requests.

What You'll Need to Request a Death Certificate

— Full legal name of the deceased
— Date of death (or approximate range)
— Place of death (city or county)
— Your relationship to the deceased
— Valid government-issued photo ID
— Social Security number of deceased (if known — helps locate the record)

Tip: If you're missing some of this information, try searching our free death index first. Our database includes dates of birth and death, county of death, parents' names, and Social Security numbers for deaths from 1940–1997.

Authorized vs. Informational Copies

California issues two types of death certificates. Authorized copies are available only to family members and legal representatives — they can be used for legal purposes like settling estates. Informational copies are available to anyone regardless of relationship — useful for genealogy and family history research. Both cost the same fee. See our complete guide to getting a death certificate for details.

Alternative: Order from CDPH

The California Department of Public Health can issue death certificates for any death that occurred in California, not just San Mateo County. This is useful if you're unsure which county the death occurred in. Processing takes 5–7 weeks by mail or 1–3 days through VitalChek online. The fee is $26 per copy. See our death certificate guide for complete CDPH ordering instructions.
