Illinois criminal records
Illinois publishes 4 of the four statewide criminal record layers, alongside 27 county jail rosters in our search roster. What a state publishes is what anyone can find — so this page states both halves.
The four statewide layers, honestly
Not every state publishes every layer, and no product can search a record a state does not publish. Where Illinois publishes nothing, this table says so rather than leaving you to assume.
| Layer | In Illinois | What it carries |
|---|---|---|
| Statewide prison (DOC) | Published | Custody status, facility and admission date — post-conviction |
| Court records | Published | Case number, filed date, charge and disposition |
| Warrants | Published | Offense, description and warrant status |
| Statewide registry | Published | Name, date of birth, classification and often an address |
County jail rosters are counted separately: Illinois contributes 27 to the roster, of which 20 answer today. Counts are a snapshot — the live list is always at /v1/criminal/sources.

What a record does and does not prove
- A jail booking is an arrest-stage record. It says someone was taken into custody on a date, on the charges recorded then — never that they were convicted
- Illinois publishes a statewide court source, so a disposition — how a case ended — is reachable here
- A Illinois warrant search reaches the statewide system — but county and municipal warrants may appear in none
- Every record cites the jurisdiction that holds it, so any answer can be checked at the source rather than trusted
