Ione, CA Mule Creek State Prison (MCSP) View

Mule Creek State Prison (MCSP) is a California state prison in Ione, Amador County, operated by the California Department of Corrections and Rehabilitation (CDCR). It is a state correctional facility, not a county jail, and primarily houses sentenced adult male inmates committed to state custody, including people serving felony prison terms and some inmates in specialized housing or programs. It generally does not serve as the local booking center for new arrests or pretrial detainees; those functions are handled by county jails and courts. The facility’s role in the justice system is to provide secure custody, supervision, and rehabilitative programming for people transferred from county custody or other CDCR institutions after sentencing or classification.

How to Find an Inmate at Mule Creek State Prison (MCSP)

To find an inmate here, use the official inmate search link available on this page, which should direct you to the appropriate CDCR inmate locator or facility roster resource. Inmate rosters or locator results typically list basic details such as the person’s name, identification number, booking or admission date, charges or commitment information, and current custody status. Because this is a state prison, records may reflect CDCR custody rather than county jail booking information. New or transferred inmates may not appear right away; intake and processing can take several hours, and search results may update after records are reviewed. If the person was recently arrested, first check the county jail where the arrest occurred before searching state prison records.

FAQs

How do I visit an inmate at Mule Creek State Prison (MCSP)?

Visits usually require the inmate to add you to an approved visiting list and for you to complete the required visitor approval process. Once approved, check the facility’s current visiting schedule and rules before traveling, because hours and procedures can change.

What do I need to bring when visiting Mule Creek State Prison (MCSP)?

Bring a valid government-issued photo ID, such as a driver’s license, state ID, passport, or military ID. Follow the dress code and property rules, and do not bring prohibited items into the facility.

How do I make phone or video calls with an inmate?

Inmates usually must place outgoing calls through the approved phone service provider, and families may need to create an account to receive calls. Video visits may be available depending on facility policy, scheduling, and the inmate’s eligibility.

How do I send mail to an inmate?

Address mail with the inmate’s full name, CDCR number, housing information if known, and the facility mailing address. Mail is inspected for safety and security, so do not send cash, prohibited items, or content that violates facility rules.

How is bail set and how do I post bond at Mule Creek State Prison (MCSP)?

What happens during the intake process at Mule Creek State Prison (MCSP) and when will the inmate appear in the system?
