Arizona State Prison Complex - Yuma Inmates

ASPC-Yuma State Prison Overview

Arizona State Prison Complex - Yuma is operated by the Arizona Department of Corrections, Rehabilitation & Reentry. The facility is in San Luis and is separate from the Yuma County Detention Center. ADCRR's page identifies Warden Oziel Romo and says the complex includes minimum, medium, and close custody institutions. It also identifies named units such as Cheyenne, Cibola, Cocopah, Dakota, and La Paz. The population held here is sentenced male state prisoners, not the mix of pretrial detainees and county/city sentenced inmates found in the county jail.

The custody distinction is the core rule for any ASPC-Yuma inmate search. Once a person is sentenced to state prison and transferred to ADCRR, the county jail roster may no longer be the right system. The county jail may show the earlier booking, but the state prison profile, location, sentence, and release information are maintained by ADCRR. Court conviction and offense details should still be verified with the court where the case was adjudicated because ADCRR warns that offense information and release details may need outside verification.

ADCRR also describes ASPC-Yuma as a major local employer, with about 960 full-time employees on its facility page. Work programs partner with local governments and agencies, including the cities of San Luis, Yuma, Somerton, Wellton, Yuma County, and ADOT. Those details matter because the prison is physically in Yuma County but is not operated by YCSO.

The ADCRR ASPC-Yuma facility page is the official source for state prison facility identity, units, and contacts.

ASPC-Yuma Capacity and Population

ADCRR's facility page says ASPC-Yuma provides housing for an average population of about 4,100 convicted male felons. The monthly data reports provide a more detailed operating picture. The December 2025 ADCRR Monthly Data Report listed ASPC-Yuma with rated capacity of 4,350, temporary capacity of 340, operating capacity of 4,690, and population of 4,751. The February 2026 report listed the ASPC-Yuma population at 4,718. September 2025 was reported at 4,760, and March 2025 at 4,681.

These numbers should not be mixed with the Yuma County Detention Center population figures. The county jail's 2025 average daily population was 424, while ASPC-Yuma is a much larger state prison for sentenced male felons.

ASPC-Yuma Inmate DataSearch

The correct locator is ADCRR Inmate DataSearch. It is a statewide prison search, not a Yuma County search. Search by ADCRR number when that number is known, or use the name fields available in the state locator. ADCRR also warns users to verify release dates, release types, and offense details with the court or another official source when accuracy matters.

1. Open ADCRR Inmate DataSearch instead of the Yuma County jail roster.
2. Search by ADCRR number when known, or search by the person's name.
3. Confirm that the current location or unit is Arizona State Prison Complex - Yuma.
4. Read release and offense information as ADCRR data, then verify adjudication details with the court of record.

The ADCRR locator page is the state search point for sentenced prisoners.

The manifest includes the official ADCRR Inmate DataSearch page for statewide prison lookup.

ASPC-Yuma Address and Contact

The ADCRR page gives the main prison address and warden office phone. Unit-specific contacts can change, and visitation calendars may list separate unit details. Call or check the current ADCRR page before sending mail, scheduling a visit, or relying on a unit assignment.

ASPC-Yuma Prison Visits

State prison visitation is handled through ADCRR approval and scheduling, not the Yuma County jail video visitation system. ADCRR publishes visitation scheduling information and unit calendars. The research identified unit names including Cheyenne, Cibola, Cocopah, Dakota, and La Paz, and noted that current unit status should be checked because older audit and current visitation materials may not describe every unit the same way.

A county jail visit rule can be wrong for ASPC-Yuma. The county jail uses public video visitation only, while state prison visits depend on ADCRR approval, inmate unit, and prison-specific scheduling.

ASPC-Yuma Mail and Money

ADCRR's prison mailing address page says Yuma unit mail uses the inmate name and ADC number with P.O. Box 8909, San Luis, AZ 85349. The inmate's name, ADC number, and unit matter because a state prison complex has multiple units. Do not use the Yuma County Detention Center's TextBehind address for ASPC-Yuma mail.

No current ASPC-Yuma deposit fee table was identified in the official facility material used here, so no fee amounts are stated. Use the current ADCRR money and inmate banking instructions when sending funds.

ASPC-Yuma Reception and Custody

ASPC-Yuma intake should be described as state prison custody after sentencing, not street-arrest booking. A person may first appear in the Yuma County Detention Center after arrest, then appear in court, then be sentenced to ADCRR if the case results in a state prison sentence. Once transferred, the public search path shifts to ADCRR and the person's county jail booking status may no longer reflect current custody.

ADCRR statute material in the research also notes prisoner record limits. A.R.S. 31-221 covers ADCRR master record files and includes access limits, including limits on inmates accessing other inmates' prison records. Public locator information is useful, but it is not the same as a complete prison file.

ASPC-Yuma Programs and Conditions

ADCRR materials list ASPC-Yuma programs including education, substance-abuse awareness, religious programming, WIPP, Changing Offender's Behavior, Courage to Change, Triple P Parenting, Gamblers Anonymous, re-entry, functional literacy, GED, high school, domestic violence, and related programming. Work programs are also tied to local public partners. Those programs are state prison programming, not county jail programming.

Recent state prison context in the research includes 2025 ADCRR safety responses after violence, including a reference to ASPC-Yuma's Dakota Unit, expanded security measures, body-worn cameras deployed in Arizona prisons, padlock and fan changes, and statewide prison healthcare litigation. These items should be treated as state prison context, not as proof about an individual inmate's conditions.

For the county-wide custody split, the Yuma County inmate population hub separates jail, state prison, federal, and immigration search paths.
