CDCR runs one statewide search tool, CIRIS, covering every state prison including SATF Corcoran.
CDCR operates a single statewide search tool, the California Incarcerated Records and Information Search (CIRIS), covering every adult institution it runs. To find someone at Substance Abuse Treatment Facility and State Prison, Corcoran (SATF), search by name or CDCR number at ciris.mt.cdcr.ca.gov, then confirm the result lists SATF, not the separate, nearby California State Prison, Corcoran (CSP-Corcoran). Since SATF houses people across Facilities A through G plus Short-Term Restricted Housing, and mail depends on which facility someone is in, it’s worth confirming the current housing detail once you know they’re here.

Visit ciris.mt.cdcr.ca.gov, CDCR’s single statewide search tool covering all 31 adult institutions, including SATF.
Enter the person’s first and last name, or their CDCR number if you already have it from court paperwork or a prior search. The CDCR number gives you the most reliable match, and you’ll need it anyway for mail, deposits, and the visitor approval process.
CIRIS should show the person’s current institution as Substance Abuse Treatment Facility and State Prison, Corcoran. Read the result carefully. Corcoran is home to 2 separate CDCR institutions, SATF and CSP-Corcoran, so a result that names the wrong one is easy to mix up if you’re not paying close attention.
Every person in CDCR custody has a unique CDCR number, usually a letter followed by five digits. You’ll find it on court paperwork, on a prior CIRIS result, or on any letter the person has sent you. It’s the most reliable way to search, and you’ll need it for the visitor questionnaire, deposits, and the mailing envelope.
Results typically include the person’s age, admission date, current institution, commitment county, and any scheduled Board of Parole Hearings dates and outcomes. CIRIS confirms whether the person is actually at SATF instead of another nearby CDCR institution.
A few common reasons: they were only recently booked into CDCR custody and the record hasn’t updated yet, they’ve been released or paroled, they transferred to another institution in the days before your search, or the name was entered with a spelling variation that doesn’t match CDCR’s records exactly.
Try name variations, including middle names or common misspellings. If you have their case number or county of commitment, CDCR’s ID Unit at (916) 445-6713 can help locate someone with a common name when you provide a date of birth.
Recheck CIRIS close to your visit date, deposit, or mailing instead of relying on older information. Transfers happen between institutions, and SATF itself houses people across multiple facilities, A through G plus Short-Term Restricted Housing, and mail depends on which one someone is in, so it’s worth confirming the exact housing detail every time you check.
