California prison records archives are split between two agencies, and knowing which one holds what saves weeks of misdirected requests. Historical files — some reaching back to 1850 — sit at the California State Archives in Sacramento, while the California Department of Corrections and Rehabilitation (CDCR) controls records on anyone currently incarcerated or recently released. Records older than 75 years are generally open to the public. Newer files carry privacy restrictions that limit what you can see.
What the State Archives Holds
The California State Archives, part of the Secretary of State’s office, receives prison documents once they’re no longer needed for operations. The two largest collections cover San Quentin (from 1850) and Folsom (from 1880). Both 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 run from 1850 through 1979 and are the single most useful tool for confirming whether a person appears in the collection at all.
The Archives also holds Youth Authority records for early California reform schools, including Whittier State School, Preston School of Industry, and the Ventura School for Girls.2California Secretary of State. California Youth Authority These registers and limited case files matter for genealogists tracing juveniles through the late 19th and early 20th centuries.
The photograph holdings are unusually deep. San Quentin identification photograph cards alone number around 65,000 items covering 1907 to 1946. Folsom’s card collection holds about 12,000 items from 1923 to 1945. Earlier photograph albums from both prisons date to the 1880s and often show inmates in both street clothes and prison garb.3California Secretary of State. Photograph Collections – Corrections Each card typically lists the inmate’s name, crime, county of sentencing, occupation, race, sentence length, age, and birthplace.
Check Digitized Records First
Before you contact the Archives, look at what’s already online. Ancestry hosts a collection titled “California, U.S., Prison and Correctional Records, 1851–1950” that includes Folsom registers (1880–1950), San Quentin registers (1851–1947), inmate photographs and mug books from both prisons, identification cards, and descriptive convict lists.4Ancestry. California, U.S., Prison and Correctional Records, 1851-1950 The collection also carries Youth Authority records and a name-change register from 1866 to 1883. Ancestry requires a paid subscription, but many public libraries provide free access through their digital resources.
This is genuinely the fastest path. If you locate the person in the digitized registers, you’ll get a commitment number that lets you request specific case files or photographs from the Archives with precision, instead of asking staff to hunt through boxes.
Information To Gather Before You Ask
Archives staff perform only limited research on your behalf. They’ll point you to the right record series but won’t dig through a full collection for one person. The more identifying detail you bring, the better.
The most valuable single item is the Department of Corrections number or prison identification number. That unique identifier follows an individual 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, plus any known aliases, maiden names, or spelling variations.
- Approximate years of incarceration. Even a decade helps narrow the search.
- The specific facility. San Quentin, Folsom, and Youth Authority records are organized separately.
- Date of birth, especially important for common names shared across decades of records.
Without a corrections number or date of birth, common-name searches can stall. If you’re starting from scratch, try the digitized Ancestry records first to pull an identification number before you write to the Archives.
How To Request Records From the State Archives
Requests go through the Archives Reference Services team. If you can’t visit in person, 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.5California 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 initial research within three to five business days, though copying and mailing take additional time.6California Secretary of State. Reference Services Once staff identify responsive records, they’ll tell you what they found and confirm duplication charges before proceeding. Photocopying fees for Secretary of State records are $1.00 for the first page and $0.50 for each additional page.7Legal Information Institute. California Code of Regulations Title 2 Section 21903.5 – Copy Fees
Visiting in Person
If you go to the Archives 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 touch the record or risk damage.8California Secretary of State. Research Room Policies and Procedures That’s a meaningful saving on any project involving heavy copying. The Archives may set reasonable limits on personal equipment to protect fragile documents.
When Staff Can’t Do the Work
Archives staff won’t conduct in-depth genealogical research or comb through an entire record series for a single document. If that’s what you need, plan to visit in person or hire an independent researcher. The National Archives maintains searchable lists of independent researchers by location and specialty, including researchers near California archival facilities.9National Archives. Independent Researchers Available for Hire They are private contractors, not government employees, so fees and scope are negotiated directly with them.
Why Some Records Are Restricted
Not everything at the Archives is open for browsing. The general rule: records more than 75 years old are open without restriction.1California Secretary of State. Genealogical and Family History Resources For anything newer, access depends on whether the file contains personal information still protected under state law.
Two laws drive most of the restrictions. The Information Practices Act protects personal information held by state agencies, including data compiled during criminal investigations and enforcement.10Franchise Tax Board. Information Practices Act of 1977 The California Public Records Act presumes government records are open, but it does not require disclosure of investigatory or security files compiled by any state or local agency for correctional, law enforcement, or licensing purposes.11California Legislative Information. California Government Code 7923.600
In practice, archival staff will check whether a record falls into a restricted category before releasing it. Records with medical information, personal identifiers, or investigative details about people who may still be alive often require a reference archivist’s review. Nineteenth- and early twentieth-century records rarely cause problems. For mid-twentieth-century files, expect a conversation with staff about what can and can’t come out.
Governor’s Clemency and Pardon Records
Pardons, commutations, and reprieves also live at the State Archives, as part of the Governor’s Records collection. The access windows differ from standard prison files: clemency and extradition case files open to the public 25 years after the case closes. The Governor may restrict other records for up to 50 years or until the Governor’s death, whichever comes later.12California Secretary of State. Governor’s Records Pardons granted before the mid-1990s should generally be accessible now.
Current or Recent Inmates Through CDCR
For anyone currently serving time or 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 limited data: name, CDCR number, age, current location, commitment county, admission date, parole eligible date, and Board of Parole Hearing dates and outcomes.13CA.gov. California Incarcerated Records and Information Search It covers people currently in CDCR custody and may contain errors or omissions.14California Department of Corrections and Rehabilitation. California Incarcerated Records and Information Search – Disclaimer
Anything beyond CIRIS 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.11California Legislative Information. California Government Code 7923.600
To submit a formal public records request, CDCR uses a third-party portal called GovQA. You can also submit by mail, email, fax, or phone; those get entered into the system by a CDCR coordinator. Portal questions go to PRPsupport@cdcr.ca.gov.15California 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 agencies and the courts.
Parole Hearing Transcripts
Parole suitability hearing transcripts are one of the few detailed correctional records California law requires to be 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.16California 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 date of the hearing. 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 separate system. State agencies do not have files on people convicted of federal crimes, even when they served their sentence inside California.
The Bureau of Prisons operates a free online inmate locator at bop.gov that searches by name, register number, FBI number, or other identifiers.17Federal Bureau of Prisons. Federal Bureau of Prisons For anything beyond locator data, you’ll need to file a Freedom of Information Act (FOIA) request. If you’re requesting records about yourself, you must verify 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.18Federal Bureau of Prisons. Freedom of Information Act Submit 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 — the PACER system provides electronic access to case files from federal district, appellate, and bankruptcy courts. PACER 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.19USCourts.gov. Find a Case (PACER) Most cases filed before 1999 exist only on paper, stored at the originating courthouse or at a Federal Records Center. The oldest federal court records eventually transfer 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 relied on. California has no formal administrative appeal. 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 only recover its fees if the case was clearly frivolous.
Before filing, write back to the agency with a detailed explanation of why the exemption shouldn’t apply. Many disputes resolve at this stage, especially when the requester can show the information doesn’t fall squarely within a correctional or investigatory exemption. When an agency won’t move on records that should be public, court is the only formal recourse left.
