San Joaquin County Inmate Search
San Joaquin County inmate population records are managed by the Sheriff's Office, which operates the county jail in French Camp just south of Stockton. The sheriff uses an ATIMS-based system called "Who's in Custody" that lets the public search current inmates by name at no cost. San Joaquin County books thousands of people each year, and the online tool shows charges, bail, booking dates, and housing assignments for anyone held at the facility. You can also use VINELink to get alerts when a San Joaquin County inmate's status changes. This page covers the main ways to search for inmates in San Joaquin County and what to expect from each tool.
San Joaquin County Quick Facts
San Joaquin Sheriff Inmate Lookup
The San Joaquin County Sheriff runs a "Who's in Custody" search tool through the ATIMS jail management system. ATIMS stands for Advanced Technology Information Management System. It is a platform that many California counties use for booking and inmate tracking. In San Joaquin County, the public-facing side of this system lets you look up current inmates by name. Type in a last name and you get a list of matches. Each result shows the person's booking number, charges, bail amount, and the date they were booked into San Joaquin County jail. The tool also shows the inmate's housing location inside the facility.
You do not need an account to search. There is no fee. The San Joaquin County inmate search is open to anyone. It runs 24 hours a day. Results update as new bookings come in and as people get released. If you search and get no results, the person may have already left custody. San Joaquin County only shows active inmates in the public tool. Past booking records are not available through the online system. For older San Joaquin County records, you would need to call the sheriff's records division at (209) 468-4562 during business hours.
Note: The ATIMS tool only covers the San Joaquin County jail. It does not show inmates held at other facilities or state prisons.
How to Find San Joaquin Inmates
Start with the sheriff's website. The "Who's in Custody" page gives you the most current San Joaquin County inmate population data. If you can not find someone there, try VINELink. VINE covers all California counties in one search. It works well when you are not sure which county holds the person. Call 1-877-411-5588 to search by phone, or go to the VINELink website and pick California. You can register for alerts too. VINE sends a call, text, or email when an inmate's custody status changes in San Joaquin County or anywhere else in California.
For people serving time in state prison who were sentenced out of San Joaquin County, use the CIRIS inmate locator instead. CIRIS is the California Department of Corrections and Rehabilitation's public search tool. It covers all 34 state prisons. It does not include county jail inmates. So if someone just got booked in San Joaquin County, CIRIS will not show them. County jail and state prison are two separate systems in California. San Joaquin County jail holds people awaiting trial, those serving sentences under a year, and parole violators. Once someone receives a state prison sentence and gets transferred from San Joaquin County, they move into the CDCR system.
The BSCC Jail Profile Survey tracks San Joaquin County jail population trends over time. This statewide survey collects monthly data from every California county on bookings, average daily population, and rated capacity. Researchers use this data to compare San Joaquin County inmate population levels against other counties.
San Joaquin County Records Access
Booking data in San Joaquin County is public. This comes from Government Code 6254(f), which says law enforcement agencies must share arrest and booking information with anyone who asks. Names, charges, bail, and booking details are all available. That is why the San Joaquin County Sheriff can post inmate data online for free. The law treats booking records as public disclosure.
Criminal history is different. Under Penal Code 11105, the California DOJ controls full criminal history records. You can not get a person's entire background through the San Joaquin County Sheriff. Only authorized agencies, certain employers, and the person can see that. San Joaquin County inmate population data gives you a current snapshot of who is in jail. It does not tell you about someone's full past. If you need your own criminal record, submit fingerprints to the DOJ through any Live Scan location in San Joaquin County. The fee is $25. Several Live Scan providers operate in Stockton and the surrounding area.
