Contra Costa County Jail Inmate Locator is a public online system that updates every ten minutes with current booking, release, and transfer data across all county detention centers. Anyone can search by full legal name, booking number, or date of birth to see where an inmate is housed, their expected release date, active warrants, and bail information. The portal connects directly to the Office of Victim Rights for verified court and charge details. For those without internet, the clerk’s office at 1011 Las Juntas Street in Martinez provides printed custody reports Monday through Friday from 8 AM to 5 PM. Call (925) 313-4260 for assistance. This tool serves families, legal professionals, victims, and community members who need fast, accurate jail records.
How to Use the Contra Costa County Inmate Locator
Searching for an inmate starts with visiting the official Sheriff’s Office website or authorized third-party portals linked to the county database. Enter the person’s full legal name exactly as it appears on court documents, or use their unique booking number if known. Alternatively, input their date of birth to narrow results when names are common. The system returns the inmate’s current location, housing unit, charges, bail amount, and next court date. Results also show whether the person has been released or transferred. All data refreshes automatically every ten minutes, ensuring near real-time accuracy. If no match appears, the individual may not be in custody, could be under a different name, or might be held in a city jail outside the county system.
Required Information for Search
- Full legal name (first and last)
- Booking number (CEN)
- Date of birth (MM/DD/YYYY)
Having at least one of these details ensures a successful search. Using multiple fields increases precision, especially for common names like “John Smith.” Avoid nicknames or shortened versions, as the system only recognizes official records.
Understanding Search Results
Each result displays key facts: current facility, housing block, booking date, charges, bail status, and projected release. Some entries include a photo and case number. If bail is posted, the release timeline appears within hours. Outstanding warrants or holds from other agencies delay release even after bail payment. Always verify information by calling the jail or checking again later, as statuses change frequently.
Official Facilities in the Contra Costa County Jail System
The Contra Costa County Sheriff’s Office operates three main detention centers: Martinez Detention Facility (MDF), West County Detention Facility (WCDF), and Richmond Jail. Each serves distinct roles based on security level, population type, and services offered. MDF acts as the primary intake hub for all arrests in the county. WCDF focuses on rehabilitation with direct-supervision models. Richmond Jail handles city-level offenders with shorter sentences. Knowing which facility holds an inmate helps families plan visits, send mail, or contact staff efficiently.
Martinez Detention Facility (MDF)
Located at 901 Court Street in Martinez, MDF opened in 1981 and remains the largest facility in the system. It houses approximately 1,200 inmates, including pre-trial detainees and short-term sentenced individuals. As the main booking center, everyone arrested in Contra Costa County passes through MDF before possible transfer. The facility offers accredited education programs, substance abuse counseling, and vocational training for about 350 participants yearly. Visitation runs 24 hours with both in-person and video options for out-of-state families. Contact MDF at (925) 335-1500 for general inquiries.
West County Detention Facility (WCDF)
WCDF sits at 1170 West Camino Avenue in Richmond and opened in 1991. It holds up to 1,096 inmates across five housing units—four for men and one for women. This facility uses a direct-supervision model where officers work alongside inmates to reduce violence and improve behavior. Programs include academic classes, a certified Substance Abuse Treatment Program (SATP), and a work-release partnership with local employers. Visitation occurs six days a week with flexible in-person and video options. Call (925) 335-1500 for details.
Richmond Jail
Richmond Jail, at 1701 Regatta Boulevard, primarily holds city-level offenders sentenced to twelve months or less. Security levels vary by offense history and risk assessment. The jail provides an online locator showing names, booking dates, and release schedules. Visitors must present government-issued ID and submit applications at least 24 hours in advance. Phone (510) 233-1214 for rules and hours.
Accessing Inmate Records Without Internet
Not everyone has reliable internet access. For these cases, the Clerk’s Office at 1011 Las Juntas Street in Martinez provides printed custody reports during business hours: Monday through Friday, 8 AM to 5 PM. Staff will search the database using your provided details and give you a physical copy of the inmate’s current status. You can also call (925) 313-4260 to request information over the phone, though complex requests may require an in-person visit. Bring valid ID and any known details about the inmate to speed up the process.
What’s Included in a Custody Report
- Current facility and housing unit
- Booking and release dates
- Charges and bail amount
- Next court appearance
- Active warrants or holds
These reports are free and available to anyone, including family, attorneys, and journalists. They comply with California’s Public Records Act and do not require proof of relationship.
Using the Office of Victim Rights (OVR) Portal
The OVR portal offers deeper access to inmate records for victims and authorized parties. To use it, you must provide either a Booking Number (CEN), Person File Number (PFN), or the inmate’s full name plus confirmed date of birth or booking date. The system cross-checks requests against state databases and returns detailed charge descriptions, bail conditions, and court schedules. This service is critical for victims tracking case progress or preparing for hearings. Note: Maintenance occurs every Monday from 12:30 AM to 2 AM, during which the portal is offline.
Why Use OVR Instead of Public Search?
OVR provides verified, official data directly from court and correctional systems. Public locators may lag or omit sensitive details. OVR ensures victims receive timely, accurate updates about defendant status, which is essential for safety planning and legal preparation.

Frequently Asked Questions About Inmate Lookup
Many people have similar questions when trying to locate someone in jail. Below are clear answers based on official policies and real user experiences.
Can I call an inmate directly?
No. Inmates cannot receive incoming calls on jail lines. All communication must go through approved third-party services like Securus or Telmate. Families set up accounts online, add funds, and schedule calls. Inmates initiate outgoing calls during designated times. Emergency messages can be relayed through jail staff, but routine contact requires prepaid systems.
How often does the inmate locator update?
The online locator refreshes every ten minutes with new booking, release, and transfer data. This near real-time sync ensures accuracy for families and legal teams. However, minor delays can occur during system maintenance or high-volume periods. For critical decisions, always confirm by phone or in person.
What if the person isn’t showing up in the search?
If no results appear, the individual may not be in county custody. They could be held in a city jail (like Richmond), transferred to state prison, released already, or booked under a different name. Try searching with alternate spellings or contact the clerk’s office for help. Also check nearby counties if the arrest occurred near a border.
Are inmate records public?
Yes. Under California law, jail records are public unless sealed by court order. Anyone can view or request basic information without proving relationship. However, sensitive details like medical records or ongoing investigation notes are protected. The system balances transparency with privacy rights.
Can I send mail to an inmate?
Yes. Mail must include the inmate’s full name, booking number, and correct facility address. Use standard envelopes—no packages, cash, or contraband. All mail is inspected. Send to: [Inmate Name], [Booking #], [Facility Name], [Address]. Rejection notices explain violations. Allow 3–5 days for delivery.

FAQs
Locating an inmate involves navigating public records, facility rules, and legal timelines. Below are detailed answers to common concerns based on official policies and user needs.
How do I find out if someone was arrested in Contra Costa County?
Start with the online inmate locator using their full name, booking number, or date of birth. If no result appears, call the clerk’s office at (925) 313-4260 during business hours. Provide as much detail as possible. If they were recently arrested, allow 2–4 hours for processing. For arrests outside the county, check adjacent jurisdictions like Alameda or Solano. Always verify with the arresting agency if known.
What happens if bail is posted?
Once bail is paid through a bondsman or cash deposit, the inmate is typically released within 2–6 hours, depending on facility workload. The locator updates immediately upon payment confirmation. However, holds from other agencies (e.g., immigration or warrants) can delay release. Families should monitor the portal and call the jail for real-time status.
Can I get a copy of an inmate’s court schedule?
Yes. The OVR portal provides scheduled court dates when you enter a valid booking number or name with date of birth. Alternatively, call the jail or visit the clerk’s office. Court calendars are also posted on the Superior Court of California, Contra Costa County website. Note that dates may change last minute due to continuances or judicial availability.
Are photos of inmates available?
Booking photos appear on the public locator if the facility uploads them. Not all entries include images due to privacy or technical reasons. For official mugshots, submit a Public Records Act request to the Sheriff’s Office. Fees may apply for processing. Unauthorized use of photos is prohibited under California law.
How do I report incorrect information on the locator?
Contact the Clerk’s Office at (925) 313-4260 or email corrections@contracostasheriff.org with the inmate’s name, booking number, and the error details. Include supporting documents if available. The office reviews and corrects discrepancies within 48 hours. For urgent issues, visit in person at 1011 Las Juntas Street, Martinez.
Can I visit an inmate the same day they’re booked?
Usually not. New inmates undergo intake, medical screening, and classification, which can take 4–12 hours. Visitation often begins the next day. Check the locator for “approved for visit” status before arriving. Some facilities allow emergency visits for critically ill relatives—call ahead to request special permission.
What if the inmate has been transferred?
The locator shows the current facility. If transferred out of county (e.g., to state prison), the record may disappear from the local system. Contact the California Department of Corrections and Rehabilitation (CDCR) inmate locator for state-level searches. Provide the person’s CDC number or full name and DOB.
