Locate North Kern State Prison Inmates

North Kern State Prison Overview

North Kern State Prison, often called NKSP, is operated by the California Department of Corrections and Rehabilitation at 2737 West Cecil Avenue in Delano. It is a state-prison facility within Kern County, but it is not a Kern County Sheriff's Office jail. NKSP is especially important in inmate-search work because CDCR identifies it as a reception center as well as a general-population medium-custody and minimum-support prison. A person recently sentenced from a Kern County court may appear at NKSP during the state intake and classification process.

Reception-center processing is different from county booking. CDCR says reception processing usually occurs within 90 days and compiles criminal, life, medical, psychological, and social histories before a classification score and institution placement are determined. NKSP also serves as the Central/Southern California Transportation Hub. That means a current-location result for North Kern State Prison may reflect a transitional stage. Families should still treat CIRIS as the public location source, but they should also be ready for later transfer to another CDCR institution.

North Kern State Prison Population

CDCR's April 15, 2026 TPOP1 report listed North Kern State Prison with 2,735 people, design capacity of 1,910, staffed capacity of 2,835, and 143.2 percent occupancy against design capacity. A separate CDCR 2024 capacity assessment, with data as of June 30, 2023, listed NKSP at 3,771 people, design capacity of 2,694, and 140 percent occupied. The April 2026 TPOP1 snapshot is the cleaner current population figure for this page, while the older assessment adds context about specialty beds and the prison's reception role.

North Kern also has medium-custody general population, minimum support, a 10-bed Level I firehouse, and reception-center functions. The 2024 capacity assessment referenced 10 mental-health crisis beds, six correctional treatment center beds, 132 DPP patients, and 11 DDP patients. Those details show why NKSP is more than a simple holding address.

North Kern State Prison Lookup

Use CDCR CIRIS to search for a person at North Kern State Prison. CIRIS is the statewide search for people in CDCR custody and may show name, CDCR number, age, current location, commitment counties, admission date, and parole hearing information. The Kern County jail roster does not track state-prison housing after a person transfers to CDCR. It may show earlier booking and hearing details, but it is not the right tool for current NKSP custody.

1. Open CIRIS and search by CDCR number when possible.
2. Use first and last name when the CDCR number is not known.
3. Check whether the current location says North Kern State Prison.
4. Remember that reception-center placement can change after classification.
5. Call CDCR Identification Unit help at (916) 445-6713 on weekdays if the locator result is unclear.

North Kern State Prison Contact

NKSP's public contact information should be used for institution-specific questions after CIRIS confirms the person is housed there. Use the prison phone for current visiting or mail-routing questions. Use court and county records only for the earlier criminal case or booking history.

North Kern State Prison Visiting

North Kern State Prison visiting follows CDCR visiting rules. Visitors should not use the Kern County Public Visiting schedule, since that schedule is for Sheriff's Office jail facilities. CDCR visits generally require visitor approval, current scheduling, valid identification, and compliance with state prison dress and conduct rules. Because NKSP has reception-center and transportation-hub functions, a person may transfer before a planned visit.

Note: Reception-center custody can move quickly, so confirm NKSP location before a long trip to Delano.

North Kern State Prison Mail

State-prison mail should include the incarcerated person's full name, CDCR number, institution name, and the correct facility P.O. Box. NKSP mail routing differs by facility. If the person is in reception processing, address details may be especially important because housing can shift. CDCR says state-prison audio calls are free as of January 1, 2023, but money and package rules should be checked through current CDCR family resources.

North Kern State Prison Intake

NKSP's reception-center role is the page's main practical distinction. County jail intake starts after arrest or remand. North Kern intake starts after CDCR receives a sentenced person into the state prison system. CDCR reviews criminal history, life history, health and mental-health information, security factors, and placement needs. The result is a classification score and an institutional placement decision. The person may remain at NKSP or move to another prison, including another Kern County CDCR facility.

For search purposes, this means the timing matters. A person may disappear from the Kern County jail roster after transfer, appear in CIRIS at North Kern, then later appear at a different CDCR prison. The lookup path is still correct as long as the user follows the system that matches the custody stage: KCSO for county jail, CDCR for sentenced state prison, BOP for federal sentenced custody, and ICE ODLS for immigration detention.

North Kern's transportation-hub role adds one more reason to verify before acting. A current location can be accurate when searched but still change after classification or transfer routing. Mail, visits, and family calls should be based on a recent CIRIS result plus institution confirmation when the matter is urgent.

About North Kern State Prison

North Kern State Prison is part of Delano's large correctional corridor, close to Kern Valley State Prison but serving a different role. CDCR also notes protected habitat on the NKSP grounds, including references to blunt-nosed leopard lizard, San Joaquin kit fox, and Tipton kangaroo rat. Those local details do not alter the search process, but they help identify NKSP as a distinct Kern County prison rather than a generic state facility.
