How to Find Someone in a California Jail
Last updated: August 26, 2026 · Inmate Information Service
California does not keep every arrested person in one database. City police jails, county sheriff jails, state prisons, federal facilities, and ICE detention are separate systems. If you search the wrong one, the result is a blank page, not proof the person is free.
This guide is the starting point. After you know the system, open the matching county or facility page on this site and search with the name used at booking.
Pick the right system first
- City police jail: Short holds after a local arrest (Anaheim, Costa Mesa, Huntington Beach, and similar). People often move to the sheriff within hours.
- County sheriff jail: Most felony bookings and anyone who does not get cited out. Use our San Diego, Orange County, Los Angeles, Riverside, San Bernardino, Fresno, and other county hubs.
- CDCR state prison: After sentencing to state time, not the night of arrest.
- Federal (BOP / U.S. Marshals): Use the federal inmate locator.
- ICE: Use the immigration inmate locator.
If you only know the city of arrest, start with that city’s jail page, then the county sheriff. People arrested near a county line are sometimes booked one county over.
What to search
- Full legal name as it appears on a license or prior booking — not a nickname.
- Date of birth. Common names collide without it.
- Approximate arrest time and agency if you have them.
Rosters often lag two to six hours after booking. A miss at midnight is not a release. Search again later the same night, then in the morning. For what the fields mean once a row appears, read what locator results mean.
If nothing comes up
- Try a middle initial, a hyphenated last name, or a previous last name.
- Call the arresting agency’s jail desk and ask which facility received the person.
- Check the neighboring county sheriff.
- If the arrest was federal or at the border, skip county search and use the federal or ICE tools.
- A probation, parole, or immigration hold can move someone after the first booking. See holds and detainers.
After you find them
Write down the facility name, booking or jacket number, housing location if shown, whether bail is listed, and the next court date. Visiting and release are different processes. Visiting guides: San Diego County and Orange County. Release options: after you locate them.
If the locator shows a set bail amount and no hold, a licensed California bail agent can explain a surety bond. One independently owned company that maintains its own site is Mr. Nice Guy Bail Bonds. This website does not write bonds and is not a bail licensee. Confirm any license with the California Department of Insurance.
Frequently asked questions
Can I search all of California with one form?
No statewide jail form covers every county in real time. Start with the arrest county, then widen.
Does a blank search mean they were never arrested?
No. It can mean a lag, a name mismatch, a city jail that is not on the sheriff roster yet, or a different system of custody.
Should I drive to the jail before the name appears?
Usually no. Confirm housing first. Jails will not discuss a person they have not booked, and visiting requires the current facility.
