Finding someone first
Nothing below works without two things: confirmation that the person is at California Institution For Women, and their CDCR number. Book a visit without them and you will be turned away; post a letter without the number and the mailroom cannot route it.
CDCR's public search covers people in CDCR custody. A disclaimer must be accepted before searching, and CDCR states the tool is informational rather than an official record. County jail populations are held separately.

Visiting California Institution For Women
This is what the institution publishes, in the order you will meet it: when visits run, how to get approved, how to book, when to arrive, and what you may carry in.
When visits run
Visiting open · 20 July 2026Get approved
You must be approved before booking. The incarcerated person first sends you a signed CDCR Form 106 Visiting Questionnaire. Complete that copy, then mail it directly to CIW’s Visiting office.
Send it to: Mail the completed questionnaire to California Institution for Women, Attention: Visiting, 16756 Chino-Corona Road, Corona, CA 92880. This is CIW’s official street/staff address.
What not to do: Do not mail the completed questionnaire back to the incarcerated person. Send it directly to CIW’s Visiting office at the address above.
Most prisons use a DIFFERENT address for mail to staff than for mail to an incarcerated person. Use the staff address. A questionnaire sent to the inmate mail address does not reach Visiting.Book through the scheduling application
Use VSA for appointments. CIW also accepts approved walk-ins after appointment processing, first come and only while space remains.
Open the Visitation Scheduling Application ↗
Walking in: Walk-ins are processed after appointments, first come and subject to space. No processing occurs after 6:00 p.m. Friday or 2:00 p.m. Saturday/Sunday.
Non-contact and restricted-housing visitsNon-contact visiting is not a choice — it is what applies while someone is in reception (newly admitted to CDCR, or just transferred between prisons) or is segregated.
Arrive, and report to visitor processing
CIW directs visitors to check QuickMap/status updates, follow signs on state grounds, and park only in authorized visitor areas. Walk-ins are not guaranteed and are processed after appointments.
Parking: Park only in CIW’s authorized visitor parking areas and follow signs to Visitor Processing. CDCR expressly prohibits visitors from parking in staff parking.
Where to report: Report to CIW Visitor Processing and follow the posted visitor route from the authorized visitor parking area. Confirm the incarcerated person’s eligibility before travel because quarantine, isolation and Test to Program requirements can override a reservation.
Bring the right things, and only those
Allowed in
- Visitors are strictly limited to CDCR's published allowed-item list: limited cash, a small clear bag, two keys, ID, a nonmetallic comb/brush, tissues, prescription glasses, limited photographs/documents, specified baby items, approved medical/religious items, and service animals. Other unauthorized property should not be brought into the visiting area.
Identification: Adults must present valid, current photo identification. Accepted forms listed by CDCR include a state driver's license or DMV ID, armed-forces photo ID, ICE ID, U.S. or foreign passport, or Mexican Consulate photo ID.
How many may visit: General-population in-person visits allow up to five visitors and generally last through normal visiting hours; non-contact visits are limited to three visitors and usually one to two hours.
Bringing a child: A visitor under 18 must be accompanied by an approved adult. CDCR requires a certified birth certificate; legal guardians also need proof of guardianship, and another accompanying adult needs the birth certificate plus an original notarized consent authorization renewed yearly.
Video visits and cost: Weekend video visiting at adult institutions ended July 7, 2023. Incarcerated people with tablets remain eligible for 15 minutes of free video calls every two weeks.
Phone calls, money and mail
Phone calls
You cannot call in. CDCR states that it is up to the incarcerated person to initiate the call, and that calls are limited to 15 minutes. That single fact explains most of what families find confusing: the switchboard will not connect you, there is no voicemail, and a call arriving from an unfamiliar number is normal. What you can do from the outside is make sure the call can reach you — that your number is not blocked by your carrier, that it is not a VoIP or virtual number the system will refuse, and that whatever account arrangement the facility uses is set up and funded before he tries. For anything urgent, a message goes through the institution rather than the phone system.
Putting money on the books
Before anything else you need the person's CDCR number, from California Incarcerated Records and Information Search (CIRIS), and their current location from CDCR's facility locator. CDCR then lists three routes. Electronic funds transfer through one of its vendors: GTL/ConnectNetwork, JPay, or Access Corrections. A lock box deposit, which CDCR states carries no fee when sent by money order, personal check or cashier's check: complete the Money Order Deposit Form with the sender's name and address, make the payment payable to JPay, and mail it to JPay, 2202 South Figueroa St, Box #3001, Los Angeles, CA 90007. CDCR caps this at $999.99 per money order, holds personal checks for ten business days, and warns that any letter or note enclosed with a payment will be discarded. Or send a check or money order to the institution itself. Vendor fees vary by amount and method, so check the vendor's own figure before you send.
Writing to someone here
Anyone may write to a person in a California state prison. Incoming letters are opened and inspected for contraband, then forwarded. CDCR asks that the envelope carry the person's full committed name and CDC number, the institution name, the P.O. box and housing assignment where known (CDCR states housing is preferable), and the city, CA and ZIP. The housing assignment is the part most people do not have: get it, and the CDCR number, from California Incarcerated Records and Information Search (CIRIS), from the institution's Public Information Officer, or from CDCR's Identification Unit. Note that the address mail goes to is not always the institution's street address, so confirm it before posting anything you cannot replace.

Inside the institution
The official history describes a campus-like design. CIW houses a large general population plus specialized populations and provides outpatient and inpatient mental-health care, including a licensed Psychiatric Inpatient Program.
Restricted housing
CIW serves as a higher-security facility for women in Administrative Segregation. The current visiting page also states that people in isolation housing are not eligible for visits and quarantine may affect eligibility.
Health care, programs and release preparation
These services differ by institution. The details below describe what this prison reports, not a systemwide promise that every person qualifies for every program.
Health care
CIW serves people with pregnancy, psychiatric, methadone, HIV, and other medical needs; provides outpatient and inpatient mental-health services, including a licensed Psychiatric Inpatient Program; and is Joint Commission accredited for ambulatory, behavioral, and nursing-care-center programs.
Education, training and work
CIW offers ABE, GED, high-school diploma and voluntary education, transition programming, multiple associate-degree programs, and bachelor's/master's programs through Adams State University, plus computer, coding, data/word processing, building-maintenance, and cosmetology training.
Preparing for release
Programs include Alpha Faith-Based Re-entry, a Transition Program, pre-release/substance-use programming, vocational education, and camp/firefighter preparation.
Reported figures
These are the institution’s own returns to the state, and every group is dated. They have to be: the figures come from separate documents on separate cadences, and reading the whole set as one snapshot would be wrong.

Clear boundaries.
Jail411 is an independent information resource for families and friends. We are not a government agency, jail operator, law firm or live custody-records service.
Can Jail411 tell me if someone is in custody right now?
No. Jail411 does not hold live custody records. Use the official locator for the county, state, federal or ICE system that has the person; start here if you do not know which.
Does posting bond mean the person comes home?
Not always. A probation or parole hold, another county's warrant or an immigration detainer can keep someone in custody after bond is posted. Ask the jail what holds are on the booking before you pay.
What should I confirm before visiting?
The person's current facility, the visiting schedule, approval requirements, accepted identification and arrival instructions. Check the facility page and its official sources before you travel.
What if I find something that needs correcting?
Send us the page and the detail that needs attention. Include the official source when you have one. Do not send private booking documents or other sensitive personal information.
