NCIS launched the Law Enforcement Information Exchange (LInX) initiative in 2003.  The project was designed to enhance information sharing between local, state, and federal law enforcement in areas of strategic importance to the Department of the Navy. LInX provides participating law enforcement partner agencies with secure access to regional crime and incident data and the tools needed to process it, enabling investigators to search across jurisdictional boundaries to help solve crimes and resolve suspicious events.

LInX sites are currently operated by NCIS and its partners in nine regions throughout the U.S. There are over 760 NCIS LInX partner agencies with approximately 30,000 trained users.

The nine regions are:

• Northwest, which encompasses 217 agencies within the State of Washington, as well as parts of Oregon and agencies within the State of Alaska;
• Hampton Roads, encompassing 106 agencies in the Norfolk and Richmond areas of Virginia;
• Southeast, with 69 agencies in the northern area of the State of Florida, as well as agencies in the southeastern area of the State of Georgia;
• Gulf Coast, with 32 agencies in the southeastern coastal area of Texas;
• Hawaii, with 6 agencies;
• Rio Grande, with 39 agencies in the central area of New Mexico;
• National Capital Region, with 126 agencies in southern Maryland, northern Virginia and the District of Columbia;
• North Carolina, with 47 agencies' data in the eastern portion of the state; and
• Southern California, comprised of 34 agencies.

A Northeast region is presently in development and includes 20 agencies in the southeastern section of Connecticut.
