Enhanced Wireless Emergency Alerts Available for Coronavirus Pandemic
The Public Safety and Homeland Security Bureau has reminded authorized alert originators that the Wireless Emergency Alert system is available as a tool during the coronavirus COVID-19 pandemic. Learn more (Posted 4/2/2020)
The Wireless Emergency Alerts system is an essential part of America's emergency preparedness. Since its launch in 2012, the WEA system has been used more than 49,000 times to warn the public about dangerous weather, missing children, and other critical situations – all through alerts on compatible cell phones and other mobile devices.
WEA is a public safety system that allows customers who own compatible mobile devices to receive geographically targeted, text-like messages alerting them of imminent threats to safety in their area.
WEA enables government officials to target emergency alerts to specific geographic areas – lower Manhattan in New York, for example.
The Warning, Alert and Response Network (WARN) Act established WEA in 2008 and it became operational in 2012.
Wireless companies volunteer to participate in WEA, which is the result of a unique public/private partnership between the Federal Emergency Management Administration, the FCC, and the United States wireless industry in order to enhance public safety.
Authorized national, state, or local government authorities may send alerts regarding public safety emergencies – such as severe weather, missing children, or the need to evacuate– using WEA.
Authorized public safety officials send WEA alerts through FEMA's Integrated Public Alert and Warning System (IPAWS) to participating wireless carriers, which then push the alerts to compatible mobile devices in the affected area.
The alerts are broadcast to the geographic area affected by an emergency. This means that if an alert is sent to a zone in New York, WEA-capable mobile devices in that zone can receive the alert, even if they are roaming or visiting from another state. In other words, a customer visiting from Chicago would be able to receive alerts in New York so long as the person has a WEA-enabled mobile device in the alert zone.
Consumers do not need to sign up for this service. WEA allows government officials to send emergency alerts to all subscribers with WEA-capable devices if their wireless carrier participates in the program.
A WEA alert appears on the screen of the recipient's handset as a text-like message. The alert is accompanied by a unique attention signal and vibration, which is particularly helpful to people with hearing or vision-related disabilities.
Yes. Consumers with prepaid phones can receive WEAs as long as their provider has decided to participate in WEA and the customer has a WEA-enabled device. These consumers receive the alerts just as customers with postpaid, monthly service do.
Participation in WEA by wireless carriers is widespread but voluntary. Some carriers may offer WEA over all or parts of their service areas or over all or only some of their wireless devices. Other carriers may not offer WEA at all. Even if you have WEA-enabled device, you would not receive WEAs in a service area where the provider is not offering WEA or if your device is roaming on a provider network that does not support the WEA service. Consumers should check with their wireless carriers to determine the extent to which they are offering WEA.
Partially. Participating wireless carriers may offer subscribers with WEA-capable handsets the ability to block alerts involving imminent threats to safety of life and/or AMBER Alerts. Consumers cannot block emergency alerts issued by the President.
In passing the WARN Act, Congress allowed participating wireless carriers to offer subscribers the capability to block all WEAs except those issued by the President.
The FCC requires all wireless carriers that do not participate in WEA to notify customers. Consumers should check with their wireless carriers to determine the extent to which they are offering WEA.
In order to receive a WEA message, your handset must be WEA-capable, switched on, and in the vicinity of and receiving service from a cell tower of a wireless carrier that participates in WEA.
Some participating carriers may offer WEA on some, but not all, of their mobile devices. Consumers should check with their wireless carriers to find out if their cell phone is WEA-capable.
WEA alerts are more geographically precise than ever before. When the WEA program launched, participating wireless providers were generally required to send the alerts to a geographic area no larger than the county or counties affected by the emergency situation. Then, beginning in November 2017, participating wireless providers were required to transmit alerts to a geographic area that best approximated the area affected by the emergency situation, even if it was smaller than a county. Now, beginning in December 2019, participating wireless providers must improve geotargeting of alerts even further. Specifically, providers must deliver the alerts to the area specified by the alert originator with no more than a 1/10 of a mile overshoot.
The WARN Act directed the FCC to adopt technical and operational requirements for WEA service. Wireless carriers that participate in WEA must adhere to the FCC’s WEA rules.
No, the FCC does not send alerts. WEA alert originators include other federal agencies (such as the National Weather Service) and state and local government authorities. Alerts from authenticated public safety officials are sent through FEMA's IPAWS system to participating wireless carriers.
For questions about how WEA works on specific devices, check with your wireless provider. For example, the method to turn optional WEA alerts on and off may vary. (The FCC recommends keeping these potentially life-saving alerts on.)
Wireless service customers should check with their wireless service provider to find out if their cell phone or mobile device is WEA-capable. Not all wireless service providers offer WEA, and some participating wireless service providers may offer WEA on some, but not all, of their mobile devices, and in some, but not all, of their service areas.
