This program is a critical component of SORNA's scheme to provide a comprehensive national sex offender registration and notification system. With a single query from any internet-connected device, NSOPW.gov enables law enforcement and the public to search state, territory and tribal public sex offender registries for public sex offender data. NSOPW.gov operates similarly to a search engine and uses web services to access registered sex offender information directly from individual jurisdictions. NSOPW.gov links to all state, territory, the District of Columbia and tribal public sex offender registries, and allows users to conduct nationwide searches for registered sex offenders with one query rather than searching jurisdiction by jurisdiction. In addition to maintenance and operation of NSOPW.gov, this cooperative agreement supports maintenance and enhancement of the SORNA Exchange Portal, a secure information-sharing system; the Tribe and Territory Sex Offender Registry System (TTSORS), a web-based sex offender registry system that is free of charge to U.S territories and Indian tribes; the Sex Offender Registry Tool (SORT), which provides a free customizable administrative registry system and public sex offender registry website for states and territories; and training for each of the technology tools and related resource development for jurisdictions.
