The County of Riverside has instituted a system that uses telephones to alert residents and businesses in Riverside County who are affected, threatened, or might be endangered by an emergency event or a disaster.
The system uses phone numbers in the region’s 9-1-1 database to contact listed and unlisted land-line telephones. It is TTY/TDD capable. If the call is picked up by an answering machine, the system will leave a voice message.
Because the 9-1-1 database includes only land-line numbers, other phone numbers must be registered. If you have a voice over Internet protocol (VoIP) or cellular telephone and would like to be notified over the device, you must register those telephone numbers to be included in the notification system.
To register your VOIP or cellular telephone, please click the "Register Now" button and complete the form. Each number will be added to the regional database within 60 days. It is important to note that each number registered can only be associated with one residential or business address in the system.
The telephone numbers you register below will be called only when a disaster or emergency affects the address associated with a telephone number.
