Mountain residents and homeowners are encouraged to register their cell phones and Voiceover Internet Protocol (VoIP) phones with San Bernardino County.
The Telephone Emergency Notification System (TENS) uses listed and unlisted numbers in the region's 911 database to alert residents of life-threatening emergencies and San Bernardino County updates this database every six months. TENS is a proven success, and has placed hundreds of calls during wildfire and flood events since its creation in 2004. However, the 911 data base only includes landline telephones, so other numbers must be registered. If a resident wishes to receive an emergency alert text message on their cell phone or an emergency call on their VoIP phone, they must register their number in the system. San Bernardino County has provided a website for residents to sign-up for this feature. Click on this link to register now:
