Find California Institution for Women Inmates

California Institution Women Overview

California Institution for Women, often called CIW, is operated by the California Department of Corrections and Rehabilitation. The institution's public address is 16756 Chino-Corona Road, Corona, CA 92880, and the main phone number listed by CDCR is (909) 597-1772. CIW is a state prison for women, not a San Bernardino County jail. A recently arrested woman may first appear in the county jail system, but a sentenced woman received by CDCR should be searched through the state prison locator.

CDCR describes CIW as a prison that houses primarily Level I and Level III female offenders while also accommodating all custody levels. Its mission includes secure custody, health care, and programs designed for women's needs. The research notes specialized populations and services, including pregnancy, psychiatric care, methadone, HIV and medical needs, administrative segregation, conservation-camp selection, outpatient mental-health care, and inpatient psychiatric treatment. That range makes it important to confirm the current location and housing through CDCR before using any mail or visiting instructions.

CIW has a distinct history in California corrections. CDCR states that it was California's only prison for female felons until 1987, was originally called "Frontera," and used a campus-like design tied to a 1950s rehabilitation model. Current prison operations are governed by CDCR rules, security classification, medical needs, program eligibility, and the institution's day-to-day status.

CIW Prison Custody

CIW should be described as sentenced state-prison custody, not county jail custody. The difference matters for searches, visits, records, and family contact. The San Bernardino County jail roster is the right tool while a person is booked locally, awaiting court, serving a local jail term, or waiting for transfer. Once CDCR receives a person after a state-prison sentence, the county jail roster may no longer show current custody. CDCR CIRIS becomes the central public locator, and CDCR family resources become the best starting point for visits, mail, money, and phone information.

California Institution Women Search

Use CDCR California Incarcerated Records and Information Search for CIW inmates. CIRIS can show the incarcerated person's name, CDCR number, age, current location, commitment counties, admission date, and Board of Parole Hearing dates or outcomes when those fields apply. It is a custody locator, not a county booking-photo gallery or San Bernardino court case portal. Court charges and case history still need the court source, while current state-prison location comes from CDCR.

1. Open CIRIS and search by CDCR number when known, or by name when the number is not known.
2. Check the current location field to confirm the person is at California Institution for Women.
3. Save the CDCR number for mail, approved visiting, phone, and family-resource questions.
4. If the result does not show CIW, use the displayed current institution rather than assuming she remains in San Bernardino County.

The CDCR CIRIS portal is the appropriate public search source for CIW custody.

The same statewide locator also helps separate CIW custody from San Bernardino County jail custody, which is covered on the county jail inmate records page.

CIW Address and Contact

The published CIW address is used for institutional contact and, according to the research, for inmate general correspondence and money orders when formatted under CDCR rules. Include the incarcerated person's name and CDCR number. Do not use a county jail booking number as a substitute for the CDCR number. For time-sensitive questions, call the institution or use CDCR family-resource channels because housing, visiting availability, and institutional status can change.

CIW Visitation Rules

CIW visits follow CDCR visiting rules and current institution status. Visitors generally need approval before they can schedule. CDCR rules cover application steps, identification, dress, allowed items, conduct, minor visitors, and visit restrictions. The CDCR schedule a visit resource should be checked close to the planned date because prisons may change visiting access by unit, day, health condition, staffing, or security status.

CIW Mail and Money

CDCR lists the main mailing address and institutional business correspondence address for CIW as 16756 Chino-Corona Road, Corona, CA 92880. The research also notes that CDCR lists inmate general correspondence and money orders to the same address. The key detail is formatting. Mail should include the incarcerated person's full name and CDCR number. Money, phone, package, and family-contact rules should be checked through CDCR family resources, since county jail iCare and county money-order rules do not apply to CIW prisoners.

CIW Programs and Care

CDCR identifies a wide program mix at CIW. Work and vocational programs include PIA clothing and textile manufacturing, construction, computer training, The Last Mile Coding Program, data processing, word processing, building maintenance, and cosmetology. Academic programs include Adult Basic Education, GED, High School Diploma Program, voluntary education, a transition program, Chaffey College, Coastline Community College, Palo Verde College, Feather River College, and Adams State University.

Health and treatment resources are part of the institution's mission. CDCR notes an Enhanced Outpatient Program, outpatient and inpatient mental-health services, a licensed Psychiatric Inpatient Program, methadone and HIV or medical care resources, Substance Use Disorder Treatment, and integrated cognitive behavioral interventions. CIW is also listed as accredited by The Joint Commission for Ambulatory Care, Behavioral Health Care, and Nursing Care Center Programs. Program access still depends on custody status, medical need, eligibility, class space, and institutional operations.

CIW Intake and Transfers

CIW intake is part of the CDCR prison process, not a local booking event. A woman arrested in San Bernardino County may first be booked into a Sheriff's jail and may appear on the county inmate locator. After a state-prison sentence and transfer, CDCR receives and classifies her. The public should then use CIRIS, the CDCR number, and the current prison location. Transfers can occur for classification, medical care, mental-health placement, programs, court needs, or security reasons, so a CIRIS location should be checked again before travel, mail, or records requests.
