CDCR - North Kern State Prison (NKSP)

North Kern State Prison (NKSP) in Delano, California, is one of CDCR's primary reception centers for the state's central and southern regions, alongside its role as a prison in its own right. For families, that means many people at NKSP are early in a CDCR sentence and may be moved to a permanent institution within weeks, while others may serve longer at Delano. Understanding NKSP's specific visiting hours and mail rules, on top of California's statewide deposit and restitution policies, is essential to staying connected. This guide brings those essentials together.

About North Kern and its dual role

NKSP serves as both a reception and classification center for newly arrived people in the CDCR system and as a functioning state prison, so its population is a mix of people at the very beginning of their sentences and those settled in for longer stays. Because reception moves quickly, a family whose loved one has just arrived at NKSP may find that they are transferred to a permanent institution within a few weeks. Every person is identified by a CDCR number that follows them across the whole state system, so writing it down early is essential.

Because California moves people between institutions as classifications change — and because NKSP's reception population is inherently transient — confirming exactly where your person is held before every visit, mailing, or deposit is the habit that saves the most frustration. Our guide on how to find someone in jail or prison explains how to trace an incarcerated person through California's CIRIS system, and you can search their name directly on AllRecentArrests.us to see their current institution and status.

Visitation process and hours

NKSP has some of the most family-friendly weekend visiting hours in the CDCR system. In-person visits run Fridays 11:30 a.m. to 6:30 p.m. and Saturdays and Sundays 8:30 a.m. to 2:30 p.m., with walk-in visitation available starting 12:30 p.m. on Friday and 9:30 a.m. on weekend days. Before you can visit, you must be an approved visitor with a CDCR Form 106 (Visitor Questionnaire) on file — your relative or friend at NKSP must send you the form and sign it before you complete and return it for a background check. Booking a visit at NKSP requires an online reservation through the CDCR visitation scheduling system, and you'll need to provide the inmate's full name, CDCR number, and your contact information.

Bring only your government-issued photo ID and the small amount of money California allows for vending machines — expect thorough security screening and a strictly enforced dress code. Our complete prison visitation guide covers approval, dress codes, and what to expect at the checkpoint, and our directory of inmate visitor application forms by state points to CDCR's forms. Because Delano is a real drive from most of California's population centers, planning around confirmed appointment times is essential.

Mail: California's strict list of prohibited items

NKSP's mail rules follow California's rigorous approach to what can and cannot enter a state prison. Send mail to the inmate's full name and CDCR number at 2737 West Cecil Avenue, PO Box 567, Delano, CA 93216, and stick to plain white paper with blue or black ink only. Prohibited items typically include cash, personal checks, stamps, stickers, glitter, glue, tape, staples, paperclips, Polaroid photos, musical or blank greeting cards, hardcover books, magazines with staples, and anything containing metal or electronics. That list is long, and one prohibited item is enough to get a letter rejected, so keeping to plain letters on plain paper is safest.

Legal or privileged mail from an attorney or a court is handled separately and more protectively under California rules and may not be opened without the incarcerated person's permission. Our breakdown of how to send mail to an inmate covers the general address format and common rejection triggers, and California's specific prohibition list means paying extra attention to what you put in an envelope.

How to send money at NKSP

Money for an NKSP inmate can be deposited electronically through Connect Network or JPay, or by mail to the CDCR lockbox. For mailed deposits, checks should be made payable to CDCR with the inmate's full name and CDCR number written on the check, and the sender's name and address on the face of the check or money order. The California-wide rule to plan around is that CDCR is required to garnish 50 percent of any non-exempt deposit toward restitution the person owes — so if you send $100 and restitution applies, only $50 reaches your loved one's spendable account.

Because of both fees and the garnishment rule, being deliberate about deposits matters. Our overview of how to send money to an inmate compares options and posting times, and our dedicated JPay guide and Access Corrections guide walk through the two electronic services California uses. Money follows a person across CDCR transfers, so a deposit made at NKSP is not wasted if your loved one is soon transferred to a permanent institution.

Phone calls, packages, and staying connected

Phone service in CDCR lets the incarcerated person place calls to numbers on their approved list, so set up and fund a prepaid account tied to your number as soon as your loved one has phone access. Under the 2026 FCC rate caps, per-minute rates have dropped sharply, and our guide to calling an inmate explains account setup and cost control. Because reception can limit phone access initially, phone contact may become more consistent once your loved one is endorsed to a permanent institution.

California allows packages, but they must come from approved vendors rather than directly from family, so the way to send goods is to order through an approved-vendor program or fund the canteen so the person can buy from the store. Our guide to sending a care package to an inmate explains how approved-vendor ordering works, and our explainer on how prison commissary works shows what a funded account buys.

Legal mail, emergencies, and avoiding scams

Legal or privileged mail from an attorney or a court is handled separately from ordinary correspondence and is generally opened only in the incarcerated person's presence when properly marked, so keep legal documents out of personal letters. For emergencies such as a death, serious illness, or birth in the family, the reliable route is to call the facility and ask how to get an urgent message to the person or their case manager, rather than trying to reach them directly, and keeping the CDCR number handy makes that call go faster. If you are worried about a loved one's medical care, mental health, or safety inside, contact the facility's staff directly, explain the situation clearly, and keep a written record of who you spoke with and when.

Be cautious, too, about where you get information and send money. The CDCR inmate search and the department's named deposit vendors are the authoritative channels, so paying an unfamiliar third-party site to "locate" a person or forward a deposit is a common way families lose money for something the state provides directly. When a rule you read online conflicts with what the facility tells you, trust the facility, and confirm anything important by calling (661) 721-2345 before you act on it.

Working with reception and long-term planning

The reception aspect of NKSP means your family may face a tension between building routines around Delano and preparing for a transfer once your loved one is classified and endorsed. The practical answer is to think in stages: use NKSP's excellent Friday-through-Sunday visiting hours if the drive is manageable, keep deposits modest since money follows the person, and get comfortable with California's specific mail rules because they apply system-wide. When your loved one is endorsed to a permanent institution, the visitor questionnaire may need to be re-processed at the receiving prison, but your deposit accounts and communication channels transfer cleanly.

Because reception is often when medical, mental-health, and treatment needs are formally identified, this is a critical window for the care your loved one will receive going forward. If they have known conditions or medications, encourage them to share that with medical staff during intake, and if you are worried about safety or care, contact NKSP staff at (661) 721-2345 directly. A clear, factual account of your concerns gets a faster response than an emotional one.

Records and staying steady

Keeping the CDCR number, current unit, the exact list of prohibited mail items, deposit receipts, and any court or classification dates organized carries families through NKSP with the least friction, especially given how detailed California's rules are. Above all, steady contact through calls, plain letters, and thoughtful use of NKSP's extended visiting hours is one of the most valuable things a family can offer someone during the disorienting early stretch of a California sentence.

Inside North Kern State Prison: how the facility is laid out

North Kern State Prison holds people at general population medium custody and a minimum support facility with a ten-bed Level I firehouse.

The institution states that it focuses on providing educational and vocational opportunities that equip people with skills to help them find gainful employment. Three hundred and sixty acres of the property is designated protected wildlife habitat.

Layout matters more than families expect. Which yard or unit someone is assigned to drives their custody level, their program eligibility, and often their visiting schedule — so when you call, having the housing assignment to hand will get you a useful answer faster than the name alone.

How crowded North Kern State Prison is right now

North Kern State Prison was designed to hold 1,910 people. As of July 22, 2026 the agency reported a population of 2,781, which is 145.6% of that design capacity.

A prison operating at this level is not simply full — it is well past the number it was built for, and that shows up in the things families actually feel. Expect converted dayrooms and gymnasiums used as housing, long waits for medical and dental appointments, program and education waitlists, and visiting slots that fill early. It also drives transfers: when one institution is over capacity, people get moved to wherever there is a bed, sometimes hundreds of miles away.

For scale, the same report puts the state's institutions as a whole at 86,006 people against a design capacity of 71,074, or 121.0% — so this facility sits above the system-wide figure rather than being an outlier.

This figure moves week to week. Treat it as the scale of the place rather than a live count, and confirm anything that affects a visit with the institution directly.

What makes North Kern State Prison different

North Kern State Prison does not operate as an ordinary general-population prison. Its designated role is reception centre processing, and that changes what you should expect from it.

North Kern operates as a reception centre, processing incoming people usually within a 90-day period while it compiles records and determines classification and onward institutional placement.

If your family member is here for a medical or mental-health reason rather than a custody one, ask specifically which unit they are on. That single answer determines their visiting schedule, their phone access, and who you need to speak to about their care.

Who runs North Kern State Prison

The senior official on site is Kevin Hixon, in post since December 2023. Naming the warden is not just trivia: correspondence about a serious unresolved problem should be addressed to that post rather than to the institution generally, because a letter to a named office creates a record that a call to a switchboard does not.

The institution's main line is (661) 721-2345. Use it for anything urgent — a medical emergency, a safety concern, confirming whether visiting is running — and ask for the watch commander or the shift supervisor rather than leaving a message with whoever answers.

Education, training, and work at North Kern State Prison

Academic programming at North Kern State Prison includes Adult Basic Education, high school and GED and English as a Second Language bridging education. Enrolment is rarely immediate — most institutions run waitlists, and assignment depends on custody level, sentence length, and prior testing. If your family member wants a place, the request has to come from them through their assigned counsellor; a call from outside will not add someone to a list.

Vocational and career technical training on site includes Small Engine Repair and Electrical Work. These carry more weight than general programming, because completion is documented and can matter at a parole or release review as evidence of work done inside.

The facility also operates prison industry work assignments: health care facility maintenance. These are paid positions, at correctional pay rates rather than market wages, and the earnings usually route into a trust account your family member can spend at the commissary. A work assignment is also the most common reason someone becomes hard to reach during the day.

Visiting North Kern State Prison: the current schedule

North Kern State Prison receives visitors on Friday, Saturday and Sunday, with in-person visits offered for a minimum of two hours, though the exact session length varies by institution and availability.

Two things about that schedule are worth knowing before you drive. Published hours are when the visiting room is open, not when you can arrive — processing closes well before the room does, and arriving inside the last hour often means being turned away. And a published schedule is suspended more often than it is changed: lockdowns, staffing shortages, and medical isolation all cancel visiting at short notice, usually without the website being updated.

Visiting is booked through the department's Visitation Scheduling Application. The booking window opens eight days before the visit and closes five days before it, and the daily request period opens at 6:00 a.m. for northern institutions, 6:30 a.m. for central, and 7:00 a.m. for southern, running to 11:59 p.m. Only people already approved as visitors can book, so the approval application has to be granted before any date can be reserved. Visits can be cancelled at any time for health and safety reasons, and can be ended early if staff see a visitor or a resident showing symptoms of a contagious illness.

Call the institution the morning you travel and ask specifically whether visiting is running on your family member's yard or unit — not whether the prison is open. Those are different questions, and the second one gets a misleadingly reassuring answer.

Your first steps

If someone you love has just arrived at North Kern State Prison, focus first on the essentials: write down their CDCR number, start the visitor application (CDCR Form 106) immediately even if they may transfer, set up an electronic Connect Network or JPay deposit knowing California withholds 50 percent for restitution, and keep letters to plain white paper in blue or black ink with none of the many prohibited items. Take advantage of NKSP's Friday-through-Sunday visiting hours if the Delano drive is manageable, and check your loved one's location often because reception is a moving target.
