The Sonoma County, California jail roster is a public resource that allows anyone to check who is currently in custody at the county jail. SonomaCourt.us provides access to publicly available information about current and recently arrested individuals. Additionally, data can be obtained through the official website of the Sonoma County Sheriff's Office, in person at the jail, or by calling the information line. A search in the roster allows you to find out the custody status, charges, and bail amount of a specific individual. The roster is maintained by the Sonoma County Sheriff's Office, it is regularly updated and posted on the county's open data portal and on the daily arrest log page.

Find Sonoma Jail Booking Records Online
A booking record is created at the moment when a detained person is officially processed into the jail. This is not the same as an arrest: booking is an administrative process during which personal data is recorded, fingerprints are taken, and a unique number is assigned.
A typical booking record includes:
- Booking number
- Date and time of processing
- List of charges with California Penal Code codes
- Name of the agency that made the arrest (e.g., Sonoma County Sheriff's Office, Sonoma Police Department, Petaluma PD, etc.)
- Gender and age of the detainee
- Status (detained, released on bail, transferred)
Online access to these data is possible through the sheriff's arrest log and the open data set. If you need information about a criminal case, not just booking, contact the case portal of the Sonoma County Superior Court or submit a request to the court's criminal division. Response time to requests usually ranges from a week to ten business days.
Search the Sonoma Jail Roster by Last Name or Booking Number
The two main search methods work differently on various platforms. Here's what you need to know.
Search by Last Name
- Open the arrest log or the open data portal.
- Enter the last name in the "Search" field. If there are too many results, add the first name.
- Check the spelling — even one letter can result in a false zero result. Try variations in spelling if the name has multiple transliterations.
Search by Booking Number
If you know the number (e.g., in the format 2025003798), enter it in the search field. This method provides an accurate result without the need to guess the spelling of the name.
If the Search Yields No Results
- The person may have already been released — the roster only reflects those currently in custody or recently processed.
- The detainee may still be undergoing the booking process, and the record has not yet appeared in the system.
- The arrest may have been made by another agency — check the agency name filter on the open data portal.
- Call the jail at (707) 565-1400 for clarification.
For court records related to a specific case, use the Case Portal of the Sonoma County Superior Court. California residents also have the right to access public records under the California Public Records Act.
Jail Roster Updates and Search Limitations in Sonoma
The arrest log on the Sonoma County Sheriff's Office website is updated daily. The county's open data portal records the date of the last data set update directly on the page.
However, there are practical limitations to keep in mind:
- Delay between arrest and record appearance. The booking process takes time — from fingerprinting to entering data into the system. The record may appear several hours after the actual arrest.
- Disappearance of records after release. The roster reflects the current custody status. When a person is released, their data usually disappears from the arrest log. This is not an archive of all past bookings.
- Data entry errors. Names are sometimes entered with errors or in abbreviated form, making the search difficult.
- Limitations on record types. Confidential records, juvenile cases, and some categories protected by California law are not displayed.
If you need historical information about arrests or bookings that is no longer available online, submit a request for court records or contact the California Department of Justice for a review of your own criminal history. For individuals transferred to state-level facilities, there is a separate system — CDCR CIRIS.
