N-DEx is an investigative tool to exchange criminal incident data across local, state, tribal, and federal justice systems. It was developed by the Criminal Justice Information Service Division (CJIS) of the Federal Bureau of Investigations (FBI). The system has been operational since March 2008.
N-DEx's services and capabilities allow participating agencies to detect relationships among people, places, property, and crime characteristics, N-DEx can link information across jurisdictions, and “connect the dots” between seemingly unrelated data without information overload. N-DEx provides contact information and collaboration tools for criminal justice agencies that are investigating cases of mutual interest. Look at the Benefits page for more.
In order to build an efficient and effective level of data exchange and incident information sharing among local, county, state, tribal, and federal agencies, the International Association of Chiefs of Police (IACP) has been working with the FBI’s CJIS division. The FBI and the IACP have designed and delivered a national outreach program about N-DEx for law enforcement and criminal justice agencies.
The FBI established the CJIS Division to serve as the central access point for criminal justice information services. The CJIS Division assumes management responsibility for the day-to-day operation of law enforcement legacy systems, the Integrated Automated Fingerprint Identification System, the National Crime Information Center, and the Uniform Crime Reporting Program.
Yes. N-DEx at www.leo.gov and the Law Enforcement Enterprise Portal (LEEP) help desk at (888) 334-4LEO are operational twenty-four hours and seven days of the week.
No. Although it is possible for a single agency to submit data to N-DEx directly, the CJIS Advisory Policy Board (APB) recommends agencies submit their data through a regional or state data sharing system.
Yes. The agency must contact its state CJIS system officer (CSO) for approval to become a user or submitting agency.
N-DEx data is as current as the information submitted and updated by participating agencies. Agencies have the option to submit data as close to real-time as possible, they also have the option of providing historical data at the time of initial data submission.
All law enforcement and eligible criminal justice agencies/representatives can access N-DEx in coordination with the state's CJIS System Officer (CSO).
Users can access exclusively through a secure portal, the Law Enforcement Enterprise Portal (LEEP), regardless if an agency is submitting data. However, the N-DEx Project Management Office has started piloting Web-based services with test agencies to have direct access to the N-DEx through their systems.
Currently, there are no restrictions on the number of N-DEx users per agency; however, access will be coordinated through the state's CSO.
The FBI's CJIS Audit Unit (CAU) will implement and manage N-DEx audit. Upon audit completion of an agency, the CAU will compile a report with audit findings and provide a draft to the N-DEx PMO and the state's CSO for review and response.
As with other computer systems, the FBI, has formally directed state-appointed CSOs to support and coordinate information sharing and submissions to N-DEx within their states. CSOs are responsible for monitoring N-DEx, NCIC and III systems' use, assuring operating procedures and discipline are followed by all users. Additionally, the local agencies’ User Administrators are also responsible for granting user access to NCIC and Ill data through N-DEx.
Data shared through N-DEx remains the property of the agency that submits it. Controls in the system allow agencies to decide what data to share, who can access it, and under what circumstances, thereby allowing agencies to participate in accordance with applicable laws and policies governing dissemination and privacy. See more on this N-DEx Data Sharing Worksheet.
Agencies have the ability to share incident/case report information, arrest/booking /incarceration data. N-DEx also includes probation and parole data.
Thousands contributing agencies representing local, county, state, tribal and federal agencies have shared their records and data in N-DEx. For example, federal law enforcement data can be accessed in N-DEx through the OneDOJ system. The amount of data and contributing agencies increase weekly. For current numbers and agencies contact an IACP or N-DEx PMO representative.
The OneDOJ system is a repository for DOJ law enforcement components (the Bureau of Alcohol, Tobacco, Firearms, and Explosives; the Bureau of Prisons; the Drug Enforcement Administration; the FBI; and the United States Marshals Service). Data that enables sharing of investigative information within the department. OneDOJ provides users the ability to search, view and analyze both OneDOJ data and data of designated partners stored in their own repositories (federated search). Currently, N-DEx and OneDOJ systems and processes are being tightly integrated by the N-DEx Program Management Office (PMO).
A federated search allows users to query multiple databases or systems with a single search from a single user interface. These data sources are independently managed systems that allow partial and controlled sharing without affecting existing applications. Once a search is completed, the results are merged into a unified format via a portal or aggregation point. For example, currently a user can query N-DEx and at the same time search the NCTC, TIT and OneDOJ data.
N-DEx provides templates and/or tags that enable criminal justice agency's Source Data Administrators to mark submitted data as GREEN, YELLOW, or RED. This capability allows agencies to share and control the dissemination of sensitive information. This tool protects the privacy of specific investigative data while conforming to their internal policies for information dissemination.
Numerous local FBI field officers and federal agency databases are shared through N-DEx. FBI field offices are being added weekly. To find out which specific field offices, please contact an IACP or N-DEx PMO representative for current members.

The helpfulness of N-DEx is increased by submitting more records and information from your system. Booking photographs and mug shots, along with images of scars, tattoos, and marks, are some of the best forms of identifying information. To widen the reach of your system and data, it is prudent to submit these images. N-DEx will also integrate crime scene and surveillance pictures.
N-DEx is the only national information-sharing system for law enforcement, however many agencies still use regional systems as well. Many of these regional systems already work with the N-DEx Program Office to coordinate and collaborate on issues such as enhancing technological strengths, information integration and sharing, and overall strategies behind the systems. To ensure that your agencies records are being forwarded from your regional system to the national system of N-DEx, contact the program manager.
