# List of U.S. Air Route Traffic Control Centers

The United States has 22 Air Route Traffic Control Centers (ARTCC). They are operated by and are part of the Federal Aviation Administration of the U.S. Department of Transportation. An ARTCC controls aircraft flying in a specified region of airspace, known as a flight information region (FIR), typically during the en route portion of flight. The purpose of control is to promote the safe, orderly, and expeditious flow of air traffic and prevent collisions. In countries other than the U.S., such a facility is generally known as an area control center.
