Emergency Alert Notifications


Help us keep you safe during a disaster by registering for emergency notification systems. Stay prepared and protect your loved ones should an emergency occur.


During a major disaster such as a wildfire, your Fire and Sheriff’s Dept. use a system known as the Telephone Emergency Notification System or TENS to send high-speed mass notifications by telephone and text messages. This system helps us get you critical updates, such as evacuation information, as quickly as possible.

In an effort to quickly communicate information on impending dangers, the San Bernardino County Sheriff and Fire Departments send high-speed mass notifications via telephone and text messages. This system is known as the Telephone Emergency Notification System (TENS).

The County uses a database of landline telephone numbers, which is updated every six months, to send emergency messages to landline phones only. By signing up below, residents can also receive emergency text messages on their cell phones, add voice over internet phone numbers (V.O.I.P.), and manage their own account using a valid email address. Those without internet connections can sign up by calling 2-1-1 or (888) 435-7565.

TENS alerts do not generally go out to the entire County but instead are targeted to affected areas.
