To ensure systems are effective in warning the public about emergencies, the Federal Emergency Management Agency and the Federal Communications Commission will be conducting a nationwide test of the Emergency Alert System and Wireless Emergency Alerts. The tests are scheduled to begin on Wednesday, October 4, 2023, at 2:20 pm ET and last for one minute.
The Wireless Emergency Alerts will reach all cell phones that are on and within range of a cell tower during the 30 minutes cell towers will be broadcasting the test. These alerts will clearly display that they are a test and will have a unique warning tone and vibration so users will always be able to discern alerts from the nation's Wireless Emergency Alerts program from other notifications they might receive on their devices. Based on a user's device settings, the alert will display either in English or Spanish. Users will additionally receive the alert as a text message.
The Emergency Alert System will broadcast to television, radio, cable and satellite outlets. These alerts will clearly state that they are a test.
Any device receiving an alert will only receive the alert once. There will be no repeats.
In the event of widespread severe weather or other significant events, FEMA and the FCC will conduct the test on their backup date of Wednesday, October 11, 2023.
