What are Wireless Emergency Alerts?
Wireless Emergency Alerts (WEAs) are emergency messages sent by authorized government agencies to inform people of imminent threats to their safety, such as natural disasters, amber alerts, and presidential alerts. These alerts are designed to be concise and timely, providing critical information to help individuals take necessary precautions to stay safe.
WEAs are typically issued by local, state, or national authorities, including the National Weather Service, the Federal Communications Commission (FCC), and the Federal Emergency Management Agency (FEMA). The alerts are transmitted to mobile devices using cell towers, allowing them to reach a wide audience quickly and effectively.
How do I receive Wireless Emergency Alerts on my Android device?
To receive WEAs on your Android device, you need to have a compatible phone with a subscription to a participating wireless provider. Most modern Android devices support WEAs, but it’s essential to check with your carrier to ensure they participate in the WEA program. Additionally, you need to have your device’s location services enabled, as WEAs are targeted to specific geographic areas.
If your device meets these requirements, you will automatically receive WEAs when an emergency alert is issued in your area. You don’t need to download any apps or take any additional steps to receive these alerts. Your device will vibrate, flash, and display a message with essential information when an emergency alert is received.
Can I Opt-Out of Wireless Emergency Alerts?
While it’s possible to opt-out of some WEAs, you cannot opt-out of presidential alerts, which are alerts issued by the President of the United States during a national emergency. These alerts are mandatory and are intended to reach all mobile devices in the country. However, you can opt-out of amber alerts and extreme weather alerts by adjusting your device’s settings.
To opt-out of WEAs on your Android device, go to Settings > Apps & notifications > Advanced > Wireless Emergency Alerts.

These guidelines include the use of a unique identifier, called a “header,” that indicates the alert is a legitimate WEA. Additionally, WEAs are typically short, concise messages that provide essential information about the emergency.
When you receive a WEA, your device will display a unique tone and vibration, and the message will be labeled as a “Wireless Emergency Alert.” This labeling helps you distinguish WEAs from other types of messages. If you’re unsure about the authenticity of an alert, you can verify the information through official government channels or local news sources.
What types of emergencies trigger Wireless Emergency Alerts?
WEAs are triggered by a variety of emergencies, including natural disasters, such as tornadoes, hurricanes, and wildfires. They may also be issued during man-made disasters, such as nuclear power plant accidents or industrial incidents. Amber alerts, which are issued when a child is abducted, are another type of WEA.
WEAs may also be issued during national emergencies, such as terrorist threats or cyberattacks. Presidential alerts, which are alerts issued by the President of the United States, are typically reserved for the most critical and severe emergencies that affect the entire country.
Can I receive Wireless Emergency Alerts in languages other than English?
Yes, Wireless Emergency Alerts can be issued in languages other than English. The FCC requires wireless providers to support WEAs in multiple languages, including Spanish, to ensure that emergency information reaches a diverse audience. This is particularly important in areas with high concentrations of non-English speakers, where timely access to emergency information can be a matter of life and death.
When a WEA is issued in a language other than English, your device will display the alert in the language it was sent in. Additionally, some WEAs may include a link to additional information or resources in multiple languages, ensuring that everyone has access to critical emergency information.
How do I prepare for an emergency when I receive a Wireless Emergency Alert?
When you receive a WEA, it’s essential to take immediate action to ensure your safety. Read the alert carefully and follow the instructions provided, which may include evacuating the area, seeking shelter, or taking other precautions. If the alert provides additional information or resources, such as a website or phone number, take advantage of those resources to stay informed.
Remember to stay calm and follow the guidance of local authorities, who are usually the best source of information during an emergency. Keep your phone charged, and try to stay connected with family and friends to ensure everyone’s safety. By taking prompt action and staying informed, you can reduce your risk and stay safe during an emergency.
