This is a private reference site, not the San Mateo County Sheriff's Office, a jail desk, a court, or a records unit. We cannot confirm whether someone is in custody, release a person, post bond, schedule a visit, or retrieve an official booking record. Use the official offices below for those actions.
Where to Ask About Jail or Records
For San Mateo County custody questions, start with the Sheriff's Office Corrections Division or the specific public-record channel that matches the record you need.

The historic Maguire inmate information line required the inmate's name and correct date of birth. The research materials did not publish a separate walk-in records counter schedule, so call first before visiting for records service. For public-record requests, use the Sheriff's Office public records request webform. If you are requesting your own records, are an involved party, or are an attorney for a client, the Sheriff's Office directs you to the report request process by email at sheriffs_recordsrequest@smcgov.org with the required ID or authorization.
- For someone currently held in a San Mateo County jail, begin with jail inmate records and the county inmate locator.
- For booking photos or photo-access limits, use the jail roster mugshots guide and the Sheriff's public-record route when the photo is not public online.
- For charges, hearings, or case numbers after arrest, check court records after a jail arrest, the court's online case access page, or MIDX.
- For facility-specific address and visitation context, use the detention facility links in the footer.
- For a sentenced California prisoner, use CDCR CIRIS, not the county jail roster.
- For federal or immigration custody, use the BOP inmate locator or ICE Online Detainee Locator System.
- For custody-change notifications, use VINELink, which is available for California VINE services.
Jail records and court records answer different questions. The jail can show custody status, facility location, pending charges, next court date, or bail when those fields are available. The San Mateo Superior Court is the better source for filed case information and docket records after charges move into court. The San Mateo County District Attorney's public contact is Stephen M. Wagstaffe, 500 County Center, 3rd Floor, Redwood City, CA 94063, (650) 363-4636.
