About US Dept. of Justice NSOPW App
This is the official U.S. Department of Justice national sex offender search app. This app is funded through a grant from the Office of Sex Offender Sentencing, Monitoring, Apprehending, Registering and Tracking (“SMART”), Office of Justice Programs, U.S. Department of Justice. SMART is responsible for The Dru Sjodin National Sex Offender Public Website (NSOPW), a public safety resource that provides the public with free access to sex offender data nationwide. This application is designed to provide additional access to NSOPW.
This app provides users with information about registered sex offenders that have residential, employment, or school addresses that are within a close proximity of the mobile device running the app. Searches can be conducted nationally using a ¼ mile, ½ mile, or 1 mile radius or by offender name. The initial search will be performed based upon the location of the mobile device, but searches can be run from other locations by tapping those locations on the map. In the event that the registering jurisdiction (state, territory, Indian tribe, or District of Columbia) for the user’s area does not allow searching by geographic coordinates for registered sex offender addresses, a zip code search will be used to find matching offenders and the results can be viewed by tapping the status message at the top of the app. NSOPW is actively working with all jurisdictions to allow searching by geographic coordinates and will modify the app searching capabilities as improvements become available.
Please be aware that when you tap the “More Information” button when viewing the details of a matching record you will be directed to the details about the particular registered sex offender on the registering jurisdiction’s public sex offender website. These websites are outside of NSOPW’s control and may not be mobile device friendly.
The purpose of this app is solely to provide users with the ability to search for registered sex offender by location and name. If you would like sexual abuse education and prevention information or have questions about sex offender registration in general please visit NSOPW at nsopw.gov.
