What is REVERSE 911©?
REVERSE 911© is the system that was selected by Imperial County in 2008 to serve as the Mass Notification System for the county. The Imperial County REVERSE 911© system has the ability to send voice, and email messages to residents during emergencies using a combination of phone database and Geographic Information Systems (GIS) Technology. Using REVERSE 911©, officials can quickly target a precise geographic area of a city or the County of Imperial as a whole and potentially reach thousands of phone numbers each hour.
Intended Use: REVERSE 911© will be used to send the following type of information to residents: evacuation notices, hazardous materials releases, community policing activities and public health emergencies. The Imperial County REVERSE 911© database currently includes both listed and unlisted landline telephone numbers, but does not include cellular, Voice Over Internet Protocol or TTY numbers (except those TTY numbers that are set up as landlines.)
Will I be guaranteed to receive a call when a disaster occurs?
No. Many situations affect the delivery of a phone message. Examples include: phone lines down, power outages, hang- ups believing it is a telemarketer, not answering a call-waiting beep, not checking voicemail, overloaded phone circuits, or any other possible scenario outside of the County's control. During an emergency, residents will still need to monitor emergency messages by radio or television broadcasts in order to receive timely notices.
Registration for Cellular, Broadband phone service, and Voice Over Internet numbers:
