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 (909) 356-3998 Monday through Friday 8:00 a.m. to 5:00 p.m. Please ask for TENS registration support.

TENS alerts do not generally go out to the entire County but instead are targeted to affected areas. You must enter a valid San Bernardino County address. This is the address for which you will receive alerts.

The County of San Bernardino utilizes multiple ways to notify residents of impending danger, but residents should not wait for or rely exclusively on any single notification system. If you are concerned about your safety and welfare, please evacuate.
