The National Data Exchange Program (N-DEx)

The Federal Bureau of Investigation’s National Data Exchange (N-DEx) System is a free online tool for sharing, searching, linking, and analyzing information across jurisdictional boundaries. A national repository of criminal justice records submitted by agencies from around the nation, the N-DEx System enables users to “connect the dots” between data on people, places, and things that may seem unrelated in order to link investigations and investigators. 

The N-DEx System is an unclassified national strategic investigate information sharing system that brings together records from across the nation.

  • No fee
  • Available 24/7
  • Easy web-based access
  • N-DEx contains incident, arrest, and booking reports; pretrial investigations; supervised release reports; calls for service; photos; and field contact and identification records.

The N-DEx System fills information gaps, provides situational awareness, and complements other well-known FBI systems, such as the National Crime Information Center (NCIC), Interstate Identification Index (III), and Next Generation Identification (NGI). Although those systems provide critical information to the criminal justice community, the N-DEx System offers additional detailed information, such as incident and case reports, full Department of Justice (DOJ) case files, and corrections data.
