A National Emergency Message (SAME code: EAN), formerly known until 2022 as an Emergency Action Notification, is the national activation of the Emergency Alert System (EAS) used to alert the residents of the United States of a national or global emergency such as a nuclear war or any other mass casualty situation. This alert can only be activated by the president of the United States or a designated representative thereof, such as the vice president. The Emergency Broadcast System (EBS) also carried the Emergency Action Notification. Except for the 2011 national test, which utilized the Emergency Action Notification alert type, no president has ever issued a National Emergency Message.
