FEMA, in coordination with the Federal Communications Commission (FCC), will conduct a national test of the Integrated Public Alert and Warning System (IPAWS) at approximately 2:20 p.m. ET on Wednesday, Oct. 4, 2023
The national test will help ensure that Wireless Emergency Alerts (WEA) and the Emergency Alert System (EAS) continue to be effective ways to warn the public about emergencies, particularly those on the national level.
All major U.S. wireless providers participate in Wireless Emergency Alerts and will transmit the national test to their subscribers.
If your mobile phone is on and within range of an active cell tower from a participating wireless provider, you should receive the national test. Wireless providers will transmit the national test for 30 minutes, but your phone should only receive it once.
The test will reach millions of mobile phones across the country via Wireless Emergency Alerts (WEA), radio and television via the Emergency Alert System (EAS), and other communication pathways.
Backup testing date is October 11, 2023.
