Searches county jail booking rosters, statewide prison systems, court sources and warrant systems across more than a thousand county, state and federal jurisdictions.

☠ lastName is REQUIRED. An unbounded criminal query is refused rather than answered from an arbitrary slice that would differ run to run — a name is the field that cannot be enumerated. Supply firstName and a dob or birthYear wherever you have them; a bare common surname matches thousands of people and the score cannot tell you which is yours.

☠ READ recordType BEFORE CHARACTERISING ANYONE. A jail booking is an ARREST-stage record — charges at booking are frequently reduced, dismissed or never filed, and it is not a conviction. Prison custody implies a sentence. A court record carries the disposition, which is the authoritative statement of how a case ended. A warrant means the person is sought and nothing has been tested.

Not a consumer report — not for FCRA-covered decisions.
