The Interagency Border Inspection System (IBIS) is a database system that keeps track of information on suspect individuals, businesses, vehicles, aircraft, and vessels. IIBIS resides on the Treasury Enforcement Communications System (TECS) at the CBP Data Center. Field level access is provided by an IBIS network with more than 24,000 computer terminals. These terminals are located at air, land, and sea ports of entry. IBIS assists the majority of the traveling public with the expeditious clearance at ports of entry while allowing the border enforcement agencies to focus their limited resources on those potential non-compliant travelers.
IBIS provides the law enforcement community with access to computer-based enforcement files of common interest. It also provides access to the FBI's National Crime Information Center (NCIC) and allows its users to interface with all fifty states via the National Law Enforcement Telecommunications System (NLETS).
