How to search the sex offender registry in any US state.
One guide per jurisdiction. Each gives the sequence for getting an answer about a named person there — how to scope the request, which criterion to send, and how to read the match label that comes back — with requests you can paste and run.
Three things worth knowing
Scope is one parameter
Name jurisdictions and the search is scoped to that jurisdiction; omit it and the identical request covers all 58 at once. Every response reports which jurisdictions answered, so a narrow search is never mistaken for a clean one.
Match strength is a label, not a boolean
A dob criterion resolves at full-date precision in 39 of the 56 jurisdictions and at year or age precision in the rest. matchState tells you which happened on every record, so your thresholds are yours to set.
One jurisdiction is rarely enough
Registration follows the person. A single-state search will not surface a registration in a prior state of residence — which is the entire argument for running the nationwide request instead.
Full-date precision
A dob criterion resolves at full-date precision in these jurisdictions and the record comes back labelled dob_match — the strongest single narrowing criterion available anywhere in the dataset.
Year precision
Here a dob criterion resolves at year precision and returns year_match. The label is the point: a same-year namesake arrives flagged as one rather than quietly accepted as a hit.
