San Mateo County Jail Booking Information
When someone is arrested in San Mateo County, they are brought to the jail for booking. This process includes fingerprinting, photographing, and recording personal details. A medical screening is also conducted to identify health needs. Booking can take several hours, depending on the number of arrests and available staff.
Steps in the Booking Process
After arrest, the individual is transported to the jail intake area. There, they are:
- Photographed (mugshot taken)
- Fingerprinted and scanned into the system
- Asked for name, date of birth, address, and emergency contact
- Searched for weapons or contraband
- Given a medical and mental health evaluation
- Assigned an inmate ID number
Once processed, the inmate is placed in a holding cell or housing unit. They will appear before a judge within 48 hours to set bail or determine next steps.
Bail and Bond Procedures
Bail is set during the first court appearance. The amount depends on the severity of the charges and the person’s criminal history. Family or friends can post bail using cash, a credit card, or through a licensed bail bondsman. Payments can be made at the jail or online via the Sheriff’s Office payment portal. Once bail is posted, the inmate is released after completing paperwork.
