West Valley Detention Center Inmate Search

West Valley Detention Center Overview

West Valley Detention Center is operated by the San Bernardino County Sheriff's Department Corrections Bureau at 9500 Etiwanda Avenue in Rancho Cucamonga. The Sheriff's official facility page identifies it as one of the largest county jails in California and gives a rated capacity of 3,347 beds. The facility holds adult county jail inmates, including pretrial detainees and sentenced local inmates assigned through Sheriff's classification.

The jail is also the key phone fallback named by the official County of San Bernardino Inmate Locator. The roster disclaimer says names of some arrested and booked people may not appear online because of public-record exemptions, and in that situation the public should contact West Valley Detention Center at (909) 350-2476. That makes West Valley important even when the person is ultimately housed at another San Bernardino County jail.

The facility page is useful for address and program context, while the Inmate Locator is still the source to confirm a specific inmate's current housing facility, visiting link, mailing address, and booking status.

West Valley Detention Center Capacity and Population

The Sheriff's facility page, inspected May 31, 2026, gives West Valley Detention Center a capacity of 3,347 beds. The same research notes that the facility completes about 50,000 to 60,000 bookings and releases each year. The research did not locate a current daily census for West Valley in the inspected official sources, so the bed count should not be read as today's population.

How to Look Up an Inmate at West Valley Detention Center

Use the county Inmate Locator for West Valley Detention Center because it is a San Bernardino County jail. The roster covers current county jail custody and also exposes out-of-custody release-date links. It is not the CDCR state-prison locator, the BOP federal locator, or ICE ODLS.

1. Open the County of San Bernardino Inmate Locator.
2. If available, enter the 10-digit booking number and use Search by Booking.
3. If no booking number is known, search by last name, first name, DOB or approximate age, and gender.
4. Open the matching profile and confirm the Housing Facility says West Valley Detention Center before visiting, mailing, or depositing money.
5. If no name appears, call West Valley at (909) 350-2476, check release-date links, or use CDCR, BOP, ICE, VINELink, or a Sheriff's public-records request as the facts require.

West Valley Detention Center Address and Contact

Use the facility contact information for custody-status follow-up, visitor logistics, and confirmation before travel. The Sheriff's research captured both the public fallback number and the facility page's visiting appointment contact.

Visiting Someone at West Valley Detention Center

West Valley visits are scheduled through the county jail workflow after the inmate record is found. The official rules say visits are first come, first served, may change without notice, and cannot be scheduled for the same day. Visitors must check in 30 minutes before the scheduled visit and bring valid government photo ID. Visitors on probation, on parole, or with a felony conviction must request authorization before scheduling.

Mail, Phone, and Money at West Valley Detention Center

Search the inmate first because the profile can show the facility-specific Inmate Mailing Address. Ordinary mail must include a return address. No more than 10 photos may be sent at one time, photos must be no larger than 5 by 7, books and magazines must come directly from a bookstore or publisher, and hardbound books are not accepted. Do not mail stamps, writing materials, snack foods, stickers, confetti, musical greeting cards, gang-related images, or sexual images.

Booking and Intake at West Valley Detention Center

San Bernardino County booking creates the public custody record after arrest by the Sheriff's Department or another law-enforcement agency. Intake normally includes identity confirmation, a booking number, property inventory, search, fingerprints, booking photograph if taken, medical and mental-health screening, classification, and housing assignment. West Valley's official page adds that arriving inmates are medically screened and evaluated for needs that may require continuing care.

The roster can show booking number, name, alias, sex, DOB, age, physical description, arrest date, arrest agency, housing facility, bail, projected release date, charges, holds, visiting information, mailing address, and VINELink release notification. Court dates on the jail profile may not be current, so use the San Bernardino County Superior Court for current case events.

About West Valley Detention Center

The Sheriff's page says West Valley Detention Center opened in 1991. It serves a large pretrial population and also provides medical, mental-health, food service, laundry, landscape maintenance, religious-service, and culinary program functions. The facility page reports more than 600 people work there, including civilian staff, maintenance crews, medical professionals, culinary staff, and support positions.

West Valley is also tied to countywide movement. The Sheriff's Transportation Division moves about 122,000 inmates and travels more than 1,000,000 miles annually, and West Valley's remote video court assignments include San Bernardino, Fontana, Rancho Cucamonga, Chino, Victorville, and Barstow courts.

That court-video detail matters for families reading a West Valley inmate record. A person may be housed in Rancho Cucamonga while the criminal case is tied to a courthouse in another part of San Bernardino County. The jail profile is the custody source, while the court portal remains the source for hearing dates and filed charges.
