Find Someone at San Quentin Rehabilitation Center

Use CIRIS, CDCR's statewide inmate search tool, at ciris.mt.cdcr.ca.gov. Search by name or CDCR number, then confirm the result lists San Quentin Rehabilitation Center.

They may be a recent booking that hasn't updated in CIRIS yet, they may have been released or paroled, they may have transferred to a different institution, or the name entered doesn't exactly match CDCR's records. Try name variations, or call CDCR's ID Unit at (916) 445-6713 with a date of birth.

Yes. San Quentin opened in 1852 as California's oldest prison, and the state renamed it a Rehabilitation Center as it shifted the mission toward programming. If older records or letters say San Quentin State Prison, this is the same institution. CIRIS lists it under its current name.

No, a name is enough to start, but the CDCR number is more reliable and you'll need it for the visitor questionnaire, mail, and JPay deposits regardless.

CIRIS updates to show his current institution, though it can lag a few days behind the actual move. Recheck it before you send money, mail anything, or travel for a visit, since JPay deposits and mail are both tied to whichever institution he's currently at.
