Find Someone at California Institution for Men

Step 1. Go to CIRIS

Visit ciris.mt.cdcr.ca.gov, CDCR’s single statewide search tool covering all 31 adult institutions, including California Institution for Men.

Step 2. Search by Name or CDCR Number

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, JPay deposits, and the visitor approval process.

Step 3. Confirm the Facility Listed

CIRIS shows the person’s current institution. Confirm it lists California Institution for Men. Because CIM is a four-facility complex, and because mail there is routed by facility (Facility A, B, C, or D), it also helps to know the person’s specific facility. If someone is in the Facility B reception center, they may be reclassified and moved, sometimes to another institution, so check close to when you act.

What the Results Show

Results typically include the person’s age, admission date, current institution, commitment county, and any scheduled Board of Parole Hearings dates and outcomes. This is the same CDCR number you’ll need for CDCR Form 106 (the visitor questionnaire), JPay deposits, and general mail.

Why Someone Might Not Show Up

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.

If You Can’t Find Them

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.

Confirming Before You Act

Recheck CIRIS close to your visit date, deposit, or mailing instead of relying on older information, since transfers between CDCR institutions happen and a facility guide’s information only applies to the institution currently holding that person.
