California prison records archives are split between two agencies, and knowing which one holds what you want saves weeks of wrong turns. Historical files, some going back to 1850, sit at the California State Archives in Sacramento. Files on anyone currently incarcerated or recently released are held by the California Department of Corrections and Rehabilitation (CDCR). Records more than 75 years old are generally open to the public; newer files carry privacy restrictions that limit what you can see.
Which Agency Holds Which Records
Start by placing the person in time. If they were in a California prison more than 75 years ago, the State Archives is almost certainly your destination, and most of what you want is probably open. If they’re in custody now, were paroled recently, or were in the system within the last few decades, CDCR controls the file and access is tighter. Federal inmates held at facilities in California are a separate system entirely, handled by the Bureau of Prisons.
What the California State Archives Holds
The State Archives, part of the Secretary of State’s office, collects prison records once they’re no longer needed for day-to-day operations. The two largest collections cover San Quentin (from 1850) and Folsom (from 1880), and include prison registers, inmate photographs, identification cards, mug books, and descriptive lists noting physical characteristics, birthplace, crime, and sentence.1California Secretary of State. Genealogical and Family History Resources Name indexes cover prison records from 1850 through 1979, which is the single most useful tool for figuring out whether a person appears in the collection at all.
The Archives also holds Youth Authority records from early California reform schools, including Whittier State School (1891–1930), Preston School of Industry (1894–1914), and the Ventura School for Girls (1907–1931).2California Secretary of State. California Youth Authority These registers and limited case files are especially useful for tracing juveniles who passed through the system in the late 19th and early 20th centuries.
Photograph collections are substantial. San Quentin identification cards alone run roughly 65,000 items from 1907 to 1946, and Folsom holds about 12,000 cards from 1923 to 1945. Earlier photograph albums from both prisons date to the 1880s. Each card typically carries the inmate’s name, crime, county of sentencing, occupation, race, sentence length, age, and birthplace alongside the photo.3California Secretary of State.

Clemency and Pardon Records
Pardons, commutations, and reprieves are part of the Governor’s Records collection at the Archives. Clemency and extradition case files open to the public 25 years after the case closes. Other Governor’s records may be restricted for up to 50 years or until the Governor’s death, whichever is later.4California Secretary of State. Governor’s Records Pardons granted before the mid-1990s should generally be accessible now.
Check Digitized Records First
Before you contact the Archives, see whether the records are already online. Ancestry hosts “California, U.S., Prison and Correctional Records, 1851–1950,” which includes Folsom registers (1880–1950), San Quentin registers (1851–1947), inmate photographs and mug books from both prisons, identification cards, descriptive convict lists, Youth Authority records, and a name-change register from 1866 to 1883.5Ancestry. California, U.S., Prison and Correctional Records, 1851-1950 Ancestry requires a paid subscription, but many public libraries offer free access through their digital resources.
This is the fastest path for genealogy. If you find the person in a digitized register, you’ll get their commitment number, which lets you ask the Archives for specific files instead of asking staff to hunt through boxes.
Access Restrictions and Privacy Rules
The general rule at the State Archives is that records more than 75 years old are open without restriction.1California Secretary of State. Genealogical and Family History Resources For newer material, access depends on whether personal information is still protected under state law.
Two statutes do most of the work. The Information Practices Act protects personal information held by state agencies, including data compiled during criminal investigations and enforcement of criminal laws.6Franchise Tax Board. Information Practices Act of 1977 The California Public Records Act presumes government records are open but exempts investigatory and security files compiled by state or local agencies for correctional, law enforcement, or licensing purposes.7California Legislative Information. California Government Code 7923.600
In practice, archival staff check whether a record falls into a restricted category before releasing it. Files containing medical information, personal identifiers, or investigative details on people who may still be alive often need a reference archivist’s review. For 1800s and early 1900s records, you’ll rarely have a problem. For mid-20th-century material, expect a conversation with staff about what can and can’t be released.
Information to Gather Before You Search
Archives staff will point you to the right record series, but they won’t comb an entire collection for one name. The more identifying detail you bring, the faster things move.
The single most valuable piece of information is the Department of Corrections number or prison identification number. It’s a unique numeric identifier that follows a person through the system and unlocks specific files. If you don’t have it, provide as much of the following as you can:
- Full legal name, with any known aliases, maiden names, or spelling variations.
- Years of incarceration, even an approximate decade.
- Specific facility (San Quentin, Folsom, and Youth Authority records are organized separately).
- Date of birth, which matters especially for common names.
Without a corrections number or date of birth, searches on common names can stall. If you’re starting from nothing, try the Ancestry collection first to pull an identification number before you write to the Archives.
How to Submit a Request to the Archives
Requests go through the Archives Reference Services team. You can reach them by phone at (916) 653-2246, by fax at (916) 653-7363, by mail at 1020 O Street, Sacramento, CA 95814, or by email through the contact form on their website.8California Secretary of State. Contact Information – California State Archives Remote requests are handled in the order received, and there is no rush processing.
Staff typically complete the initial research within three to five business days, with additional time for copying and mailing.9California Secretary of State. Reference Services Once staff identify responsive records, they’ll let you know what they found and confirm duplication charges before proceeding. Photocopying fees are $1.00 for the first page and $0.50 for each additional page.10Legal Information Institute. California Code of Regulations Title 2 Section 21903.5 – Copy Fees
Visiting in Person
If you come to the research room in Sacramento, you can review records directly and use your own camera or scanner to copy documents at no charge, as long as the method doesn’t require contact with the record and won’t damage it.11California Secretary of State. Research Room Policies and Procedures For large volumes of material, this is a real cost saver. Staff may set reasonable limits on personal equipment to protect fragile documents.
Current or Recently Incarcerated People Through CDCR
If the person is currently serving time or was recently released from a California state prison, CDCR holds the records. The fastest way to confirm basic details is the California Incarcerated Records and Information Search (CIRIS), a free online tool that returns the person’s name, CDCR number, age, current location, commitment county, admission date, parole eligible date, and Board of Parole Hearing dates and outcomes.12CA.gov. California Incarcerated Records and Information Search It covers people currently in CDCR custody and may contain errors or omissions.13California Department of Corrections and Rehabilitation. California Incarcerated Records and Information Search – Disclaimer
Anything beyond CIRIS data is harder to get. Full inmate case files are generally available only to the incarcerated person or their authorized legal representative. The CPRA’s correctional-records exemption gives CDCR broad discretion to withhold investigatory and security files from the public.7California Legislative Information. California Government Code 7923.600
To file a formal public records request, CDCR uses a third-party portal called GovQA. You can also submit by mail, email, fax, or phone, and a CDCR coordinator will enter the request. Questions about the portal go to PRPsupport@cdcr.ca.gov.14California Department of Corrections and Rehabilitation. CDCR – Records Request Management CDCR does not hold arrest reports, body camera footage, or court documents; those come from local law enforcement and the courts.
Parole Hearing Transcripts
Parole suitability hearing transcripts are one of the few detailed correctional records that California law requires be made public. Under Penal Code 3042(b), the Board of Parole Hearings must record and transcribe every hearing for a person serving a life sentence and make the transcript available to the public within 30 days of the hearing.15California Department of Corrections and Rehabilitation. Request for Parole Suitability Hearing Transcript
To request one, you’ll need the incarcerated person’s name, CDCR number, and the hearing date. Copies cost 12 cents per page whether delivered electronically or by mail, with postage added for printed copies. Hearings from 2001 and earlier may be on microfilm and carry the same per-page charge. Payment must be by check or cashier’s check made payable to the California Department of Corrections and Rehabilitation. Mail requests to:

Federal Inmates in California Facilities
California hosts several federal prisons, and federal records follow a completely different system. State agencies won’t have files on anyone convicted of a federal crime.
The Bureau of Prisons runs a free online inmate locator at bop.gov that searches by name, register number, FBI number, or other identifiers.16Federal Bureau of Prisons. Federal Bureau of Prisons Anything beyond locator data requires a Freedom of Information Act request. For records about yourself, you must verify your identity with your full name, current address, date and place of birth, and register number if applicable, along with a signed DOJ-361 form or a notarized statement. Requests about someone else require that person’s written authorization.17Federal Bureau of Prisons. Freedom of Information Act FOIA requests can be sent by email to BOP-OGC-EFOIA-S@BOP.GOV or by mail to the FOIA/PA Section, Office of General Counsel, Room 924, Federal Bureau of Prisons, 320 First Street N.W., Washington, DC 20534.
For federal court records — sentencing documents, plea agreements, judgments — use PACER. It charges 10 cents per page up to a $3.00 cap per document, and fees are waived if you accrue less than $30 in a quarter.18USCourts.gov. Find a Case (PACER) Most cases filed before 1999 exist only on paper, stored at the originating courthouse or a Federal Records Center, with the oldest material eventually transferred to the National Archives.
If Your Request Is Denied
Under the CPRA, when an agency denies all or part of your request, it must identify the specific exemption it’s relying on. California doesn’t have a formal administrative appeal process. Your remedy is to petition the superior court in the county where the records are maintained, under Government Code section 7923.100. You carry the burden of proving the agency violated the act, and the agency gets a presumption that it acted reasonably. If you win, the court may award your attorney’s fees and costs. If you lose, the agency can recover its fees only if your case was clearly frivolous.
Before going to court, write back to the agency and explain why the exemption shouldn’t apply. Many disputes resolve at that stage, especially when you can show the information doesn’t fall squarely within a correctional or investigatory exemption. If the agency still won’t release records that should be public, the courthouse is your only formal recourse.
