A Contra Costa County arrest usually means the county jail. A state sentence, a federal case or an immigration hold means a different system with its own locator and rules.

Understand jail and prison differences

Clear information.
Clear boundaries.

Jail411 is an independent information resource for families and friends. We are not a government agency, jail operator, law firm or live custody-records service.

How do I find someone in Contra Costa County custody?

Use the official Contra Costa Sheriff In-Custody Locator linked on this page. If the person is not listed or the booking is recent, call (925) 335-4600 and ask which facility currently holds them.

Which adult jail should I use?

The guide lists Martinez Detention Facility, West County Detention Facility, Marsh Creek Detention Facility. Use the facility shown in the current custody record, not simply the closest building, and reconfirm before traveling or sending anything.

What should I confirm before visiting?

Sheriff Visiting an Inmate (Wayback captured 2026-06, checked 2026-09-12): social visits are scheduled only by the inmates. Arrive 30 minutes early with government photo ID. Confirm the building on the In-Custody Locator before you drive. Martinez (901 Court Street) hours differ from West County / WRTH (5555 Giant Highway) and Marsh Creek (Saturday–Sunday 1 p.m. and 2 p.m. only). No contact. Cell phones, bags, and food stay out of visiting. Do not use adult visiting for Juvenile Hall.

Where should I send mail?

Sheriff Sending Mail to an Inmate (Wayback, policy effective November 1, 2022; page captured 2026-06): non-privileged letters to Pigeonly, PO Box 96777, Las Vegas, NV 89193, with booked name, booking number, and facility code 1117 (Martinez), 1118 (West County / WRTH), or 1119 (Marsh Creek). pigeonly.com to create/send/track. Legal mail, money orders/cashier’s checks/government checks, and publisher magazines/newspapers/periodicals/soft-cover books go to the jail street — not Las Vegas. Legal mail street: Martinez 901 Court Street, Martinez, CA 94553; West County 5555 Giant Highway, Richmond, CA 94806; Marsh Creek 12000 Marsh Creek Road, Clayton, CA 94517. Do not send adult-jail Pigeonly, MyCarePack, or SmartDeposit to John A. Davis Juvenile Hall (202 Glacier Drive) or to Concord Police at 1350 Galindo Street.

How do phone calls and commissary money work?

Phone service: Telephone vendor name not published on Sheriff Inmate Information pages checked 2026-09-12. Commissary or deposit service: MyCarePack (mycarepack.com); SmartDeposit / Access Corrections deposits. Confirm the current facility and account type before paying.

Do youth use the adult jail rules?

No. John A. Davis Juvenile Hall is handled through Contra Costa County Probation Department. Contra Costa County Probation operates this hall at 202 Glacier Drive, Martinez. Official Juvenile Hall page (checked 2026-09-12): opened June 2005; 270-bed maximum-security detention for youth up to age 25. Hall (925) 957-2700 (Mon–Fri 8 a.m.–5 p.m.); after 5 p.m. and weekends (925) 957-2740. Not the adult jail. Do not use Pigeonly, MyCarePack, or SmartDeposit.

Does posting bail guarantee release?

Confirm custody and the booking number on the In-Custody Locator, then post cash or a licensed bail bond. Jail411 does not republish a bondsman directory. Superior Court publishes 2026 felony and misdemeanor bail schedules effective July 8, 2026 at contracosta.courts.ca.gov/divisions/criminal. Criminal clerk hours Monday–Friday 8:00 a.m.–4:00 p.m. Main court phone (925) 608-1000. Custody Alternative Facility (1011 Las Juntas Street, Martinez, (925) 313-4260) is sentenced work alternative / electronic home detention — not walk-in bail. Posting a bond does not guarantee release if a hold applies. An ICE detainer alone is not a lawful California hold (Gov. Code § 7284.6).

How do I report a correction?

Use Jail411's contact page and include the page URL plus an official agency source. Do not send private booking documents, medical records, or other sensitive personal information.
