California State Prison, Sacramento Overview
The official CDCR California State Prison, Sacramento page identifies CSP-Sacramento at 100 Prison Road in Represa. CDCR describes it as a prison for maximum and high-security offenders and people requiring specialized mental-health programming and high-risk medical care. It is a state institution, not a county jail, even though it sits inside Sacramento County.
CSP-Sacramento is primarily a Level IV institution with a Level I Minimum Support Facility. CDCR describes 24 semi-autonomous housing units designed for 180 each, a stand-alone Administrative Segregation Unit, a lethal electrified perimeter, and mental health levels that include Correctional Clinical Case Management System, Enhanced Outpatient Program, and Mental Health Crisis Bed. These details make it materially different from Folsom State Prison and from the Sheriff's Main Jail and RCCC.
The facility's population also differs from county jail custody in legal status and record source. Main Jail and RCCC can hold people before trial, people serving county jail sentences, parole violators, transport cases, and contracted populations. CSP-Sacramento houses sentenced state prisoners and specialized CDCR populations after the state has accepted custody. That means a person can have a Sacramento arrest, a Sacramento court case, and a CSP-Sacramento location, but the current custody lookup still belongs to CDCR.
California State Prison, Sacramento Capacity and Population
The CDCR Weekly TPOP1 report dated April 15, 2026 reported California State Prison, Sacramento population at 2,224. The same report listed design capacity as 1,828, equal to 121.7 percent occupied, and staffed capacity as 2,493. These are CDCR prison measures and should not be combined with Sacramento County jail average daily population for Main Jail and RCCC.
The report's staffed capacity of 2,493 adds operational context, but it does not replace an individual locator search. For a specific person, the current location field in CDCR CIRIS is more important than the prison's overall population percentage.
How to Look Up an Inmate at California State Prison, Sacramento
Use CDCR CIRIS for CSP-Sacramento. The Sacramento Sheriff roster covers county jail custody, not CDCR prisons. CIRIS allows search by first and last name or CDCR number, and the CDCR number is the stronger search key for common names. CA.gov describes CIRIS result information as including current location, commitment county, admission date, and parole-hearing information where applicable.
This image is used only to show the statewide CDCR locator. The manifest did not include a successful CSP-Sacramento facility screenshot, so no facility image is substituted.
- Open CDCR CIRIS.
- Search by CDCR number if known, or use first and last name.
- Confirm the current location field, because Folsom-area prisons are separate institutions.
- Use CDCR visiting, mail, and family-resource instructions after the location is confirmed.
If the person is awaiting trial or recently booked on a local Sacramento County arrest, start with the Sheriff Inmate Information portal instead. If the person is a federal defendant or sentenced federal inmate, use BOP or U.S. Marshals channels. CDCR CIRIS is not a county jail roster or federal custody locator.
For Sacramento County context before prison transfer, Sheriff Jim Cooper's office operates Sheriff Inmate Information for county jail custody, Sacramento Superior Court provides Criminal Public Case Access for filed court cases, and the Sheriff's warrant services page explains identity-verified warrant access. Those local routes may explain how a case reached CDCR, but they are not the current prison locator.
CIRIS records have their own limits. CDCR describes the locator as informational and not an official record, and the research warns that data can contain errors or omissions. Still, the current location field, CDCR number, admission date, and commitment county are the key pieces for families trying to determine whether the person is at CSP-Sacramento, Folsom State Prison, another CDCR institution, or no longer in CDCR custody.
California State Prison, Sacramento Address and Contact
Use the CSP-Sacramento contact details for facility-specific questions after confirming the person is housed there. For locator assistance, the research lists the CDCR Identification Unit assistance number as 916-445-6713.

Visiting Someone at California State Prison, Sacramento
CSP-Sacramento visiting follows CDCR rules, not Sacramento County jail rules. Main Jail's two-visit social schedule and RCCC's classification schedule do not apply to state prison visitors. CDCR prison visiting commonly requires approval, scheduling, valid identification, compliance with search and dress rules, and facility-specific confirmation before travel.
| Visit Topic | CSP-Sacramento Rule Path | Type |
|---|---|---|
| Approval | Use CDCR visiting resources and facility instructions | State prison |
| Scheduling | Confirm through CDCR before travel | State prison |
| Security level | Level IV and specialized mental-health operations may affect local procedures | State prison |
| Location check | Confirm in CIRIS before relying on older court or jail information | Lookup |
Mail, Phone, and Money at California State Prison, Sacramento
CSP-Sacramento mail, money, phone, package, and family communication rules must come from CDCR resources and the CSP-Sacramento facility page. Sacramento County jail details such as Securus Digital Mail Center, TouchPay/GTL facility number 257501, Main Jail visiting booths, RCCC release pickup, and SIRENS release notifications are county jail processes. They do not govern a person housed at CSP-Sacramento.
| Service | Provider / Detail |
|---|---|
| Mail address | Use CSP-Sacramento/CDCR mailing instructions and include the person's CDCR number |
| Phone and communication | Use CDCR family resources for current prison communication procedures |
| Money and packages | Use CDCR-approved prison family-resource routes |
| County jail services | Do not use Sheriff jail mail, TouchPay/GTL jail deposits, or SIRENS for CSP-Sacramento |
Reception, Transfer, and Criminal Cases at CSP-Sacramento
CSP-Sacramento is not the place where street arrests are booked into Sacramento County jail. A local arrest normally begins with the Sheriff jail system, then the case may move through Sacramento Superior Court and the Sacramento County District Attorney's filing process. If a defendant receives a state-prison sentence, transport may move through RCCC before CDCR takes custody.
Crimes occurring inside CSP-Sacramento can still have local criminal-case consequences. The Sacramento County District Attorney's Office has a Prison Crimes unit that may prosecute crimes at state prison facilities in Sacramento County, including crimes by inmates, staff, visitors, state-prison inmates in transit, and escape-status matters. That prosecutorial connection does not make CSP-Sacramento a county jail.
Because CSP-Sacramento and Folsom State Prison share the broader Represa correctional landscape, a current location check matters. A reference to "New Folsom," "CSP-Sac," or "Folsom" in older family notes may not match the current CDCR location field. Confirm the CDCR number, then confirm the current institution before sending mail or planning a visit.
For people following a Sacramento County case, the sequence may involve several agencies over time. The Sheriff handles jail booking and county custody, the District Attorney reviews and prosecutes charges, Sacramento Superior Court controls filed court records and hearings, RCCC may serve as a transport point after a prison sentence, and CDCR controls custody after state transfer. Keeping that sequence in order prevents mistaken calls to the jail after the person has already become a state prisoner.
About California State Prison, Sacramento
CDCR states CSP-Sacramento sits on 882 acres sharing property with Folsom State Prison, Folsom Women's Facility, and California Prison Industry Authority. The institution opened in 1986 as New Folsom, was initially administered by the Folsom warden, and became California State Prison, Sacramento in October 1992. CDCR says it was the first California institution to achieve American Correctional Association accreditation in 2012, with a 98.6 percent score.
CDCR page material says rehabilitative opportunities include educational programming, vocational training, self-help programs, and mental-health treatment on all facilities. The harvested source listed Jason Schultz as Warden after appointment in August 2025. Because CSP-Sacramento houses high-security and specialized-care populations, current facility instructions should be checked before mail, visiting, or family contact.
The official page's mental-health and medical-care language is not just background. It explains why visiting, movement, housing, and communication instructions may be more sensitive to classification and treatment status than a county jail visitor expects. A person may be in a specialized mental-health level or high-risk medical setting while still appearing in the statewide locator as a CSP-Sacramento prisoner.
Note: Confirm current CDCR location, visiting approval, and facility instructions before traveling to CSP-Sacramento.
