CDCR runs one statewide search tool, CIRIS, covering every state prison including California State Prison, Sacramento.
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 California State Prison, Sacramento, search by name or CDCR number at ciris.mt.cdcr.ca.gov, then confirm the result lists California State Prison, Sacramento specifically, not the separate, adjacent Folsom State Prison or Folsom Women’s Facility.
Find your loved one and start staying in touch - photos, letters, and calls.
Visit ciris.mt.cdcr.ca.gov, CDCR’s single statewide search tool covering all 31 adult institutions, including California State Prison, Sacramento.
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 California State Prison, Sacramento. Read this carefully: CSP-Sacramento sits on the same property as Folsom State Prison and Folsom Women’s Facility, and these are 3 separate institutions with their own wardens, addresses, and rules. If CIRIS lists one of those other 2 facilities instead, the guides on this page won’t apply, and you’ll need that institution’s own contact information.
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 shows the specific institution, which matters here since it’s the detail that tells you whether the person is at CSP-Sacramento or at one of the 2 other separate institutions on the same property.
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, and a facility guide’s information only applies to the specific institution currently holding that person, not the general area or property it sits on.
