To do a California inmate release date lookup, use the California Incarcerated Records and Information Search (CIRIS) at ciris.mt.cdcr.ca.gov for anyone in state prison, the county sheriff’s inmate roster for someone in a county jail, or the Federal Bureau of Prisons locator at bop.gov for a federal facility.1California Department of Corrections and Rehabilitation. California Incarcerated Records and Information Search Each system shows a different kind of date, and none of them is final until the day the person actually walks out.
Looking Up a State Prison Inmate on CIRIS
CIRIS is run by the California Department of Corrections and Rehabilitation and covers people currently held in state prison. The quickest search uses the person’s CDCR number, the unique identifier assigned at intake. Without it, search by full legal name and add a date of birth to narrow the results when the name is common.
A record pulls up the person’s name, CDCR number, age, current facility, commitment county, admission date, and, for people serving fixed sentences, a parole eligible date. For those serving indeterminate sentences, it shows parole hearing dates and outcomes.2CA.gov. California Incarcerated Records and Information Search CDCR’s own disclaimer warns that the database may contain errors or omissions and should not be treated as an official legal record.1California Department of Corrections and Rehabilitation.

If a search comes up empty, call the CDCR Identification Unit at (916) 445-6713.1California Department of Corrections and Rehabilitation.

You can also contact the records office at the institution if you already know where they’re housed.
What the Date on the Record Actually Means
The date CIRIS displays depends on the type of sentence, and the difference matters.
Fixed Sentences
Someone sentenced to a specific number of years has a determinate sentence. The record shows an Earliest Possible Release Date (EPRD), which is the court-imposed sentence reduced by any credits earned.3California Department of Corrections and Rehabilitation. Parole Eligibility This is the number most people are looking for. It moves forward or backward as credits are earned or lost.
Life Sentences
Someone sentenced to life with the possibility of parole has no guaranteed release date. The record instead shows a Minimum Eligible Parole Date (MEPD), the earliest the Board of Parole Hearings can even consider them for release.3California Department of Corrections and Rehabilitation. Parole Eligibility Reaching the MEPD only triggers a suitability hearing, where a panel decides whether the person poses an unreasonable risk to the community.
Even a favorable hearing does not produce an immediate release. Parole decisions are proposed and become final within 120 days, during which the Board’s legal division reviews every grant and the Governor has 30 days to review the final decision. For a murder conviction the Governor can reverse the grant outright; for other offenses the Governor can send it back to the full Board for another vote.4California Department of Corrections and Rehabilitation. What to Expect After a Parole Suitability Hearing An actual release date for someone serving a life sentence is not knowable until months after a hearing goes well.
Why the Release Date Can Shift
The EPRD you see today is almost always earlier than the full court-imposed sentence because of Good Conduct Credit, awarded for work, programming, and following facility rules. The credit rate depends on the nature of the conviction. Nonviolent offenses earn credit at 50% (one day off for each day served), while violent offenses earn at 33.3% (one day off for every two days served).5California Department of Corrections and Rehabilitation. Frequently Asked Questions on Good Conduct Credits Minimum-custody nonviolent inmates and fire camp workers can earn at higher rates, and additional credits for completing educational or vocational programs stack on top.6California Department of Corrections and Rehabilitation. In-Prison Credit-Earning Opportunities
Credits are not guaranteed. Someone who refuses a work assignment or commits a serious disciplinary infraction can be placed in a non-credit-earning work group and stops accumulating Good Conduct Credit entirely.7California Department of Corrections and Rehabilitation. California Code of Regulations Title 15 – Credit Earning That is the most common reason a release date you checked a few months ago no longer matches what CIRIS shows today.
Looking Up a County Jail Inmate
CIRIS does not cover county jails. For someone serving time locally, search the Sheriff’s department website for that county. Most California counties publish an online jail roster or booking search, though the detail varies. Some display a scheduled release date, others only the booking date and charges.
Credit earning in jail is governed by Penal Code 4019. For every four days spent in custody, a person can earn two days of credit, one for satisfactory work and one for following the rules. When all credits are earned, four days of a sentence are considered served for every two days actually spent in custody.8California Legislative Information. California Code PEN – 4019 A 180-day jail sentence with full credits often means release after roughly 90 days. If the sheriff’s roster does not post a date, that formula gives a reasonable estimate once you account for any pre-sentencing custody.
Looking Up a Federal Inmate Held in California
People in federal custody, including those at facilities in Atwater, Lompoc, Mendota, Victorville, and the Los Angeles Metropolitan Detention Center, do not appear in CIRIS.9Federal Bureau of Prisons. Locations By Name The Federal Bureau of Prisons runs its own locator at bop.gov, covering all federal inmates from 1982 to the present. You can search by name or by BOP register number.10Federal Bureau of Prisons. Find an Inmate
The BOP locator displays a projected release date. That date reflects the judge’s sentence reduced by anticipated Good Conduct Time, which under federal law allows up to 54 days per year, so inmates typically serve about 85% of the sentence if they stay out of disciplinary trouble. Credits earned under the First Step Act for completing rehabilitative programs are not always reflected on the public locator right away and are applied only after internal BOP review. For a precise breakdown, the inmate or their attorney can request a Sentence Computation Data sheet from the facility’s unit team.
Getting Notified Instead of Checking Manually
If you need to know the moment custody status changes, you do not have to keep refreshing a database. California participates in the Victim Information and Notification Everyday (VINE) system, a free service that sends automated alerts by phone, email, or text when an inmate is released, transferred, or has another status change. Register at vinelink.com, choose California, and search by name or booking number.11VINELink. VINELink Phone registration is available at 1-877-411-5588.
One catch worth knowing: a VINE registration for a county jail inmate does not automatically follow the person into state prison. You will get a transfer notification, but you then need to re-register under the CDCR system to keep receiving updates. The same is true in reverse when someone moves from state to county custody.
