How to Look Up Someone in Marin County Jail Right Now

1. Open Marin County’s online booking log - This is the County’s public search tool for jail custody information.
2. Search using the person’s identifying details - Enter the name (and any other details you have) and run the search to pull matching results.

The booking log shows public data for people arrested and booked into the County jail within the last 48 hours - but only if they're still in custody. Very recent arrests might not appear yet, and someone who's already been released won't show up either.

The search also pulls up a complete list of current inmates at the moment you run it. It's a real-time snapshot - results shift as people get booked, released, or moved through the system.

See a bail figure on the booking log? Treat it as a rough estimate, not the final number. The log itself warns that bail amounts shown may be approximations. For exact bail information, call the Sheriff's Office at (415) 473-6653.

Don't see the person you're looking for? Try again later and double-check your spelling. The booking log covers recent 48-hour bookings for people still in custody, and the inmate list only reflects the moment you search. Timing matters, and small typos can throw off results.
