The roster must show this jail. If the person is at West County or WRTH, use 5555 Giant Highway, Richmond. If Marsh Creek, use 12000 Marsh Creek Road, Clayton. If Juvenile Hall, use 202 Glacier Drive — not this door.

Money and commissary

- 01

- 02
Credit/debit cards: kiosks in the Martinez and West County Detention Facility lobbies; website www.smartdeposit.com (redirects to Access Corrections).

The live Deposit Money HTML captured in 2026 truncated the telephone deposit number (printed as 1-866-0460). Jail411 does not invent the missing digits. Use the kiosk or smartdeposit.com, or call (925) 335-4600.

Release and property
Bail, property, and commissary pickup
Search first, then cash or a licensed bond — Criminal Division is 725 Court Street
Confirm the person is still here on the In-Custody Locator or (925) 335-4600. Post cash or a licensed bail bond — Jail411 does not republish a bondsman directory. Superior Court Criminal Division clerk Monday–Friday 8:00 a.m.–4:00 p.m., (925) 608-1000. 2026 felony and misdemeanor bail schedules effective July 8, 2026 are on contracosta.courts.ca.gov/divisions/criminal.

Posting a bond does not guarantee release if a probation, parole, or out-of-county hold applies. An ICE detainer alone is not a lawful California hold (Gov. Code § 7284.6).
