How to Find Someone’s Criminal History
Criminal records are largely public — but they are scattered across thousands of county courts, state repositories, and federal systems, and what you can see depends heavily on the state. There is no single free national database the public can search. This guide shows you where criminal history actually lives, what is open and what is not, how to tell an arrest from a conviction, the one limit that governs hiring and tenant decisions, and when a professional is worth it.
The Short Version
Most criminal records are public, but they are fragmented: convictions are filed at the county court where the case was heard, compiled in state repositories, and — for federal cases — in the federal PACER system, while the sex-offender registry is separate and public. There is no free, all-in-one national criminal database for private citizens; the “national” database professionals use is a licensed, aggregated product. Access rules vary by state — some let anyone search, others, like California, release a person’s record only to that person. An arrest is not a conviction, and sealed, expunged, and juvenile records are generally off-limits. Verify any hit against identifiers before you rely on it, and remember you cannot use a self-run search to make a hiring or tenant decision.
Watch: Finding Criminal History
Where the records live, what is public, and the limits that matter.
Watch Overview
Where Criminal Records Live
Four separate places — there is no single search box.
County courts. This is the source of truth. A criminal case is filed and decided in the county where it happened, and most counties offer an online case-search portal. Because records sit at the county level, a thorough search means checking every county where a person has lived — which is exactly why a single online lookup misses so much. See how to find someone’s court records.
State repositories. Each state’s bureau of investigation compiles records from its counties. Some states publish a public criminal-history search; others restrict access.
Federal courts. Federal crimes are not in state systems — they live in PACER, the federal courts’ online records system, which charges a small per-page fee.
Sex-offender registry. Separate, nationwide, and fully public; see how to check the registry in your area.
What Is Public — and What Is Not
The rules change at the state line.
What you can see depends on the state. In many states a private citizen can search conviction records and view the offense, the disposition, and the sentence. In others, access is tightly limited: California, for example, does not release a person’s criminal history to third parties at all — only the individual can request their own record, by fingerprint. Across every state, certain records are walled off: juvenile records are usually confidential, and sealed or expunged records are removed from public view by law. And one distinction trips people up constantly — an arrest is not a conviction. A charge that was dropped or that ended in acquittal is not proof of anything, and treating it as such can be both unfair and, in a regulated decision, unlawful.
The Limit That Governs Decisions
Knowledge is one thing; a regulated decision is another.
You can look up someone’s criminal history for your own knowledge or personal safety. But the moment you use it to decide whether to hire, rent to, lend to, or insure someone, you are in Fair Credit Reporting Act territory, which requires a consumer report from a compliant agency with disclosure, authorization, and adverse-action steps. A self-run county search cannot be used for those decisions. For that, see our background checks and the dedicated criminal background check service, plus the FCRA compliance guide.
Verify Before You Rely
A name match is not the right person.
Criminal records are a minefield for false matches. Common names collide constantly, instant sites attach records to the wrong person, and an old charge can show up without its dismissal. Before you act, confirm a record against identifiers — full name, date of birth, and a known address — and check the disposition, not just the charge. The difference between “arrested” and “convicted,” and between two people who share a name, is the difference between a fact and a defamation problem.
Checking Your Own Record
Know what an employer or landlord will see.
You have the clearest right to your own criminal history. Most states let you request your record from the state bureau of investigation, usually by fingerprint, and the FBI offers an Identity History Summary for your nationwide record. It is worth doing before a job or housing search: you will see what others see, and you can correct an error or prepare to explain a record before it costs you an opportunity.
When to Use a Professional
Fragmentation is exactly where do-it-yourself breaks down.
Because records sit county by county, a complete criminal-history picture means knowing every place a person has lived and searching each one — then verifying every hit. That is slow and error-prone by hand. A professional combines the licensed national database with county-level confirmation and identifier verification, so you get a checked result rather than a guess. For a hiring or tenancy decision, that comes as a compliant background check. If you first need to find the person — to know which counties even apply — that is our skip-tracing services, where a verified locate typically comes back within 24 hours. For the broader method, see how to run a background check on someone.

Frequently Asked Questions
Is there a free national criminal database I can search?
Not for the public. Records are filed at the county level and compiled by states; the “national” criminal database is a licensed, aggregated product used by professionals. Free public searching means going county by county and checking state portals where they exist.
Are criminal records public?
Mostly, but it varies by state. Many states let anyone search conviction records; some, like California, release a person’s record only to that person. Juvenile, sealed, and expunged records are generally not public anywhere.
Is an arrest the same as a conviction?
No. An arrest only means someone was taken into custody; the case may have been dropped or ended in acquittal. Always check the disposition, and never treat an arrest as proof of guilt.
Can I use criminal history to decide whether to hire or rent to someone?
Not from a self-run search. Those decisions are governed by the FCRA and require a compliant consumer report with disclosure, authorization, and adverse-action steps.
How do I check my own criminal record?
Request it from your state bureau of investigation, usually by fingerprint, and use the FBI’s Identity History Summary for your nationwide record. It is wise to do before a job or housing search so you can correct errors first.
Why hire a professional for this?
Because records are scattered county by county and full of false matches. A professional searches the right jurisdictions, uses the licensed national database, and verifies each hit, delivering a confirmed result rather than guesswork.
Need a Verified Criminal-History Search?
For personal knowledge, a private investigative search; for a hiring or tenancy decision, a compliant report; and if you first need to locate the person, a verified locate, typically within 24 hours.
