California doesn’t run a separate inmate search tool for each prison. Instead, CDCR maintains one statewide locator, CIRIS (California Incarcerated Records and Information Search), that covers every institution including California Rehabilitation Center. Search by name or CDCR number to confirm someone’s current location.
Go to ciris.mt.cdcr.ca.gov and enter the person’s first and last name, or their CDCR number if you have it. CDCR number searches are more reliable since names can have multiple spellings or common matches. The tool returns basic identifying information along with the institution where the person is currently housed.
Since CIRIS is a statewide tool, a search can return someone housed at any CDCR institution, not only California Rehabilitation Center. Double check the result specifically lists California Rehabilitation Center before assuming that’s where to send mail, money, or plan a visit.
A few common reasons a name doesn’t appear in CIRIS: they were only recently sentenced and haven’t been transferred from county jail yet, they were released, they’re housed under a legal name different from the one you searched, or there’s a temporary lag between an actual transfer and CIRIS updating.
Try searching with only the last name, or double-check the spelling of both names. If you have their CDCR number from a previous letter or court document, search with that instead, since it’s less prone to name-matching errors. If you still can’t locate them, call CRC’s Public Information Officer at (951) 737-2683, or check with the county court where they were sentenced to confirm their custody status.
If someone you’re tracking gets transferred to a different CDCR institution, CIRIS updates to reflect their new location, though there can be a short delay. Before sending mail, money, or scheduling a visit, always recheck CIRIS close to the date you plan to act, since transfers can happen with little notice.
