To do a California inmate release date lookup, start with the California Incarcerated Records and Information Search (CIRIS) at ciris.mt.cdcr.ca.gov if the person is in state prison.1California Department of Corrections and Rehabilitation. California Incarcerated Records and Information Search For someone in a county jail, use that county sheriff’s inmate roster. For a federal facility, use the Federal Bureau of Prisons locator at bop.gov. Which tool you need depends entirely on where the person is held, and each one reports release information differently.
Looking Up a State Prisoner on CIRIS
CIRIS is the California Department of Corrections and Rehabilitation’s public search for anyone currently in a state prison. The fastest lookup is by CDCR number, the unique identifier assigned at intake. If you don’t have it, search by full legal name and add a date of birth if the name is common.
A record returns the person’s name, CDCR number, age, current facility, commitment county, and admission date. For someone on a fixed-length sentence, it also shows a parole eligible date. For someone serving a life sentence, it shows parole hearing dates and outcomes.2CA.gov. California Incarcerated Records and Information Search CDCR warns that the database may contain errors or omissions and shouldn’t be treated as an official legal record.1California Department of Corrections and Rehabilitation.

If nothing comes up, or the record is missing what you need, call the CDCR Identification Unit at (916) 445-6713.1California Department of Corrections and Rehabilitation. California Incarcerated Records and Information Search The person may have been transferred, released, or booked under a different name. You can also contact the records office at the specific institution if you know where they’re housed.
What the Date on the Record Actually Means
The label on the date matters. CDCR uses different terms depending on the sentence, and confusing the two leads to bad expectations.
Fixed-Length Sentences
Someone sentenced to a specific number of years has a determinate sentence. Their record shows an Earliest Possible Release Date (EPRD), which is the date they will leave custody after the court-imposed sentence is reduced by earned credits.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. Their record shows a Minimum Eligible Parole Date (MEPD), the earliest the Board of Parole Hearings can consider them for release.3California Department of Corrections and Rehabilitation. Parole Eligibility Reaching the MEPD only means a suitability hearing can be scheduled. It is not a release date.
Even when a panel grants parole, the decision is proposed for 120 days while the Board’s legal division reviews it and the Governor has 30 days to act. The Governor can reverse a parole grant outright in a murder case, or refer other cases back to the full Board.4California Department of Corrections and Rehabilitation. What to Expect After a Parole Suitability Hearing The actual release date for a lifer often isn’t known until months after a favorable hearing.
Why the Date You See Can Change
The EPRD on CIRIS is almost always earlier than the full court-imposed sentence, and it can shift, because of Good Conduct Credit (GCC). California awards these credits for work, education, vocational training, and following facility rules. The rate depends on the offense.
Since December 2021, following Proposition 57 changes, credit rates in state prison are:5California Department of Corrections and Rehabilitation. In-Prison Credit-Earning Opportunities
- Nonviolent offenses: 50%, or one day of credit for every day served, which roughly halves the sentence.
- Violent offenses: 33.3%, or one day of credit for every two days served.6California Department of Corrections and Rehabilitation. Frequently Asked Questions on Good Conduct Credits
- Minimum-custody nonviolent offenses: 66.6% for those in minimum-security housing or eligible for it.
- Fire camp workers: 66.6% for nonviolent offenses, 50% for violent offenses.5California Department of Corrections and Rehabilitation. In-Prison Credit-Earning Opportunities
On top of GCC, people in state prison can earn Milestone Completion Credits for finishing educational or vocational programs, Rehabilitative Achievement Credits, and Educational Merit Credits. These stack and can pull the release date closer.5California 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 is placed in a non-credit-earning work group and stops accumulating GCC.7California Department of Corrections and Rehabilitation. California Code of Regulations Title 15 – Credit Earning When that happens, the EPRD moves later. It is the most common reason a date you checked months ago no longer matches what CIRIS shows today.
Looking Up Someone in a County Jail
CIRIS does not cover county jails. To find a release date for a jail inmate, go to the sheriff’s website for the county where the person is held and use its inmate lookup or booking search. Detail varies. Some show a scheduled release date; others show only the booking date and charges.
Jail credits follow a different statute. Under Penal Code 4019, for every four days in custody, a person can earn two days of credit: one for satisfactory work performance and one for following facility rules. With full credits, four days of a sentence are considered served for every two days actually spent in custody.8California Legislative Information. California Code PEN – 4019 So a 180-day jail sentence, with full credits, can result in release after roughly 90 days. For most jail sentences, taking the sentence length, subtracting any pre-sentence time already served, and halving the remainder produces a workable estimate.
Looking Up a Federal Inmate Held in California
California hosts several federal facilities, including institutions in Atwater, Lompoc, Mendota, and Victorville, and the Los Angeles Metropolitan Detention Center.9Federal Bureau of Prisons. Locations By Name People held there do not appear in CIRIS. Use the Federal Bureau of Prisons inmate locator at bop.gov, which covers all federal inmates from 1982 to the present.10Federal Bureau of Prisons. Find an Inmate
The BOP locator displays a projected release date. That date reflects the judge’s sentence minus anticipated Good Conduct Time, which under federal law allows up to 54 days off per year of the sentence. In practice, that works out to roughly 85% of the sentence served, assuming no disciplinary issues. Credits earned under the First Step Act for completing rehabilitative programs are not always reflected on the public locator right away and apply 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 Alerts Instead of Checking Manually
If you need to know the moment someone’s custody status changes, you don’t have to keep opening a database. California participates in the Victim Information and Notification Everyday (VINE) system, which sends automated alerts by phone, email, or text when an inmate is released, transferred, or otherwise changes status. Register at vinelink.com, select 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 carry over if the person is transferred to state prison. You will receive a transfer notification, but you have to re-register under the CDCR system to keep getting updates. The same applies in reverse when someone moves from state to county custody.
