The Dru Sjodin National Sex Offender Public Website (NSOPW) searches every state at once — but it only shows what each state chooses to publish, and states differ enormously. The state guides below explain each registry's visibility rules, because 'not on the registry' can mean very different things.
All 51 jurisdiction guides linked below are maintained individually. Content reviewed July 30, 2026 by the SearchSystems editorial team.
How the States Differ
Publication rules are the real story. Minnesota publishes only Level 3 (highest-risk) offenders; Oregon's public site shows fewer than one in ten registrants; Washington's is run by the sheriffs' association rather than the state police; and California excludes whole categories by statute. In tier states, low-tier offenders are registered with police but invisible to the public.
Search behavior differs too: some states geo-search by address radius with maps and email alerts, others only take names. The state page tells you which tools exist and what the gaps are.
