Booking Details and Process
When an individual is arrested in San Mateo County, they are taken into custody and processed through the booking system at one of the county’s detention facilities. The booking process begins with identity verification, fingerprinting, and photographing. Personal belongings are inventoried and stored securely. Medical and mental health screenings are conducted to assess immediate needs. The inmate is then assigned a unique booking number, which is used to track their case throughout their stay. This number is essential for all future inquiries, including visitation requests, phone calls, and legal communications. Booking information is entered into the county’s database within hours of arrest and becomes available in the inmate lookup system shortly thereafter.

Custody Status and Housing Information
Once booked, each inmate is assigned a custody status that reflects their current situation within the jail system. This status determines housing location, privileges, and eligibility for programs. Common custody levels include maximum, medium, minimum, and protective custody. Housing assignments are based on factors such as behavior, charge severity, medical needs, and safety concerns. Inmates may be moved between units as their status changes. The San Mateo County inmate database displays the current housing unit for each individual, allowing family and legal counsel to know exactly where the person is located. This information is updated in real time and is accessible through the online search tool.

Understanding Search Results
When you perform a San Mateo County inmate search, the results page displays a list of individuals matching your query.

The system may return multiple results if names are common, so it’s important to verify details like age and booking date to ensure accuracy.
