Terrorist Screening Center


Leading the U.S. government’s consolidated approach to terrorism watchlisting/screening.

That’s what the Terrorist Screening Center, or TSC, is all about. Born out of the events of 9/11 and created in 2003, the TSC maintains the U.S. government’s consolidated Terrorist Watchlist—a single database of identifying information about those known or reasonably suspected of being involved in terrorist activity.

By supporting the ability of front-line screening agencies to positively identify known or suspected terrorists trying to obtain visas, enter the country, board aircraft, or engage in other activity, the consolidated Terrorist Watchlist is one of the most effective counterterrorism tools for the U.S. government.
