CDCR - California State Prison - Centinela (CEN)

California State Prison, Centinela (CEN) is a CDCR men's institution at 2302 Brown Road in Imperial, California, about 15 miles south of Calipatria State Prison and roughly 100 miles east of San Diego in California's Imperial Valley near the Mexican border. Opened in 1993, Centinela houses General Population inmates at Level I, Level III, and Level III sensitive-needs classifications, plus maximum-security housing, spread across facility yards A, B, C, D, and E. Under Acting Warden Andre Green, appointed in January 2026, and Health Care CEO Dr. Muhammad Nasir (appointed April 20, 2026), Centinela is one of the more distinctive CDCR facilities in that each of its five facility yards uses its own P.O. Box for inmate mail — a routing detail that catches many families off guard. This guide covers weekend visitation through the CDCR VSA, yard-specific mail routing, Connect Network and JPay deposits, free ViaPath phone calls, and the Imperial Valley setting.

About CSP Centinela and its yard-based structure

Centinela opened in 1993 to hold roughly 3,000 men and is one of the two big CDCR institutions in Imperial County, alongside Calipatria State Prison about 15 miles to the north. The prison is organized as five facility yards labeled A through E, with each yard operating semi-independently for movement, program access, and mail routing. That yard structure is the single most important practical detail for families: each yard uses its own P.O. Box for inmate mail, so a letter addressed to the wrong yard's PO Box will be delayed or returned. Facility A uses PO Box 901, B uses 911, C uses 921, and Facilities D and E share PO Box 931, all in Imperial, CA 92251 with the corresponding four-digit ZIP+4 suffix. Confirm your loved one's current yard assignment before every mailing, and update your address book whenever he is moved between yards internally.

Under Acting Warden Andre Green (in the role since January 2026) and Health Care CEO Dr. Muhammad Nasir (appointed April 20, 2026), Centinela's leadership team has been reshaped in the past year. Every incarcerated person at Centinela has a CDCR number that follows him across California's whole system; that number is required on every letter, deposit, and visit form. Confirm the current institution through CDCR's CIRIS or by searching on AllRecentArrests.us before mailing or traveling. Because CDCR moves people between institutions and internal yards as classification and sensitive-needs status change, our guide on how to find someone in jail or prison is worth a read.

Centinela's Level III sensitive-needs yard designation is worth understanding: sensitive-needs (SNY) placement is for men whose safety cannot be maintained in general population because of their conviction type, gang status, or other factors that would make them targets. SNY yards operate separately from general-population yards even on the same institution, so an SNY inmate and a general-population inmate at Centinela may effectively never encounter each other despite being at the same prison.

Visitation at Centinela through the CDCR VSA

Visits at Centinela are held on Saturdays, Sundays, and CDCR-observed holidays. Every visit must be scheduled in advance through the CDCR Visitor Scheduling Application (VSA) at cdcr.gtlvisitme.com/app — walk-in visits are turned away. Depending on the incarcerated person's custody status and yard, visits may be contact (in a shared visiting room) or non-contact (through a partition); Level III and sensitive-needs yards may have specific visiting-room protocols distinct from Level I minimum-support.

Before scheduling, you must be approved on the visitor list. The process starts inside the prison: the incarcerated person requests CDCR Form 106 (Visitor Questionnaire), mails it to you, and you complete and return it for a background check. Approval typically takes several weeks. Bring a valid government-issued photo ID, dress within CDCR's visiting-room rules (no clothing resembling the inmate uniform — blue denim, khaki, camouflage; no gang colors, no revealing clothing, no open-toed shoes), and expect a full search on arrival. Only a small amount of cash is allowed inside for vending machines. Because Imperial County summers are extreme (routinely above 110°F), plan travel for early morning arrival and carry extra water in your vehicle.

How to send money to a Centinela inmate

Centinela inmates fund their trust and canteen accounts through the CDCR-wide channels: Access Corrections' Connect Network and JPay for electronic deposits, plus a mailed-check option through JPay's Los Angeles lockbox. Connect Network is the CDCR-contracted trust deposit route (accesscorrections.com or by phone) and typically posts fastest. JPay handles both electronic deposits and mailed checks; money orders and checks should be made payable to JPay and sent with a completed JPay deposit slip to JPay, 2202 South Figueroa St, Box #3001, Los Angeles, CA 90007.

The California-wide rule to plan around is CDCR's requirement to garnish 50 percent of any non-exempt deposit toward restitution the person owes, so if your loved one has a restitution balance, only half of what you send may reach spendable. Deposits stay with the person across CDCR transfers, including internal yard moves at Centinela. Our how to send money to an inmate and JPay guide cover the mechanics.

Mail to a Centinela inmate: yard-specific P.O. Boxes

Personal mail for Centinela inmates is routed by facility yard:

• Facility A: Inmate Name and CDCR Number, PO Box 901, Imperial, CA 92251-0901
• Facility B: Inmate Name and CDCR Number, PO Box 911, Imperial, CA 92251-0911
• Facility C: Inmate Name and CDCR Number, PO Box 921, Imperial, CA 92251-0921
• Facilities D & E: Inmate Name and CDCR Number, PO Box 931, Imperial, CA 92251-0931

Using the wrong yard's PO Box will delay or prevent delivery. Ask your loved one for his current yard and update your address list whenever he is moved internally. Include your full return address; letters without one are frequently rejected. Legal mail from an attorney or court, clearly marked as legal correspondence, is opened only in the inmate's presence and should be sent separately from personal letters. Follow California's prohibited-items rules: no cash, personal checks, stamps, stickers, glitter, glue, tape, staples, paperclips, Polaroids, hardcover books, musical or embellished cards, or anything with electronics. Our how to send mail to an inmate covers the format and common rejection triggers.

Phone calls: free through ViaPath since January 2023

Phone service at Centinela, like every CDCR institution, has been free of charge to the incarcerated caller since January 1, 2023 under California's Keep Families Connected Act (SB 1008). Calls run through ViaPath/GTL's ConnectNetwork platform. Register your phone number at connectnetwork.com on the inmate's approved calling list before your loved one can dial you. Given the Imperial Valley's distance from most California population centers, free phone contact has become the mainstay of many family relationships with Centinela inmates. Packages are allowed only through CDCR-approved vendors. Our guide to calling an inmate, care package guide, and commissary explainer cover the details.

Legal mail, emergencies, and avoiding scams

Legal or privileged mail is opened only in the inmate's presence when properly marked. For urgent family emergencies such as a death, serious illness, or birth, call Centinela at (760) 337-7900 and ask to be connected to the chaplain's office to relay the message. Keep the CDCR number handy. If you are worried about a loved one's medical care, mental health, or safety inside, contact staff directly, keep a written record of who you spoke with and when, and escalate in writing if the initial response is inadequate. External escalation paths include the Prison Law Office, the ACLU of California, and the CDCR Office of the Ombudsman.

Be cautious about paying third-party sites — CDCR's CIRIS search and the department's named providers are the authoritative channels. Paying an unfamiliar site to "locate" someone or forward a deposit is a common way families lose money.

Inside Centinela State Prison: how the facility is laid out

Centinela State Prison opened in 1993 near the town of Imperial, and takes its name from Mount Signal — centinela is Spanish for sentinel — the mountain on the United States–Mexico line once used to watch the state's borders. The facility holds people at Level I, Level III, Level III sensitive needs and maximum security Level IV. It employs roughly 1,200 people, which is worth knowing when you are trying to reach someone: a facility of that size routes calls through departments rather than individuals, so asking for the right department by name saves a great deal of time.

Centinela State Prison states that it attempts to achieve productivity and self-improvement by providing legally mandated work and study opportunities.

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 Centinela State Prison is right now

Centinela State Prison was designed to hold 2,308 people. As of July 22, 2026 the agency reported a population of 3,233, which is 140.1% 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.

Who runs Centinela State Prison

The senior official on site is Andre Green, appointed acting warden in January 2026. 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 (760) 337-7900. 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 Centinela State Prison

Academic programming at Centinela State Prison includes Adult Basic Education I, II and III, GED, the Voluntary Education Program, independent study and a literacy lab. 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 Electrical, Office Services and Related Technologies, Building Maintenance, Small Engine Repair, Auto Body, Auto Mechanics, Electronics, Roofing and Welding. 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.

Visiting Centinela State Prison: the current schedule

Centinela 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 an appointment, so the approval application has to be completed and 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.

Before you travel or send anything

Whatever a directory tells you — including this one — confirm the detail that matters to you with the operating agency before acting on it. Facility names, operators, designations and even addresses change, sometimes years before public records catch up, and the cost of acting on a stale entry is a wasted journey, a returned parcel or a deposit sent to the wrong account. A single phone call the morning you travel is worth more than any amount of research the week before.

If a search for someone returns nothing at all, work through the possibilities in order before assuming the worst. They may be held by a different authority than the one you are searching — a county sheriff rather than a state department, or the reverse. They may be in transit between facilities and temporarily unlisted. The name on the record may differ from the one you use, particularly where a middle name, a suffix or a hyphenated surname is involved. Or the record may simply not have updated yet, which is common in the first day or two after an arrest or a move. An empty result is far more often a search problem than a sign that something has gone wrong.

Records and your first steps at Centinela

Keeping the CDCR number, current yard assignment (A, B, C, D, or E), VSA login, Connect Network/JPay receipts, and any Board of Parole Hearings dates organized in one place carries families through Centinela with the least added friction. If someone you love has just been transferred to Centinela, focus first on the essentials: write down their CDCR number and current facility yard, request CDCR Form 106 for visitor approval and register at cdcr.gtlvisitme.com/app once approved, set up Connect Network or JPay for deposits (knowing California withholds 50 percent for restitution), and use the correct yard-specific PO Box for personal mail.
