In cases of impending danger the Riverside and/or San Bernardino County Sheriff and Fire Departments send high-speed mass notifications via telephone and text messages. In an effort to quickly communicate information about what is occurring. This system is known as the Telephone Emergency Notification System (TENS).
The counties use a database of landline telephone numbers, which is updated every six months, to send emergency messages to landline phones only. However, more and more residents have moved away from landlines and rely exclusively on cell phones for telecommunications. 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 211 or (909) 980-2857 for assistance in registering.
TENS alerts do not generally go out to the entire county but instead are targeted to affected areas. To sign up, you are required to enter a valid San Bernardino County address as this is the address for which you will be alerted. In San Bernardino County click here to register.
