Emergency Notifications (TENS)
During an emergency, the County of San Bernardino uses a system known as the Telephone Emergency Notification System (TENS) to send high-speed mass notifications by telephone and text messages. If you only use a mobile phone or have more than one mobile phone in your family, it's important for you to register those mobile numbers in TENS to receive these critical updates. Help us keep you safe during a disaster by registering your mobile phone number now.
