Register Your Cell Phone and E-mail for Emergency Notification

Residents who live in San Diego County, which includes all 18 cities and the unincorporated areas of the County, are encouraged to register their cell phones and e-mail addresses for emergency notifications by visiting www.alertsandiego.org within the next few days.

Once e-mail addresses and cell phone numbers are registered, it will take up to 24 hours for that information to be updated into AlertSanDiego, the County of San Diego mass notification system that is commonly referred to Reverse 911.

AlertSanDiego will provide emergency alerts to your cell phone and e-mail address including evacuation notices. This is in addition to the land line calls received by those who have land line phones.

Residents are able to register multiple cell phone numbers and e-mail addresses by reopening the Web page. Residents without computers may access the Web site from one of the County libraries. There is no charge to use the computers at County libraries.

If a City resident has registered a cell phone number with the City of San Diego Reverse 9-1-1 system, that information is automatically shared with the County cell phone registry. To register an e-mail address computer users must register with the County system.

Please note that while the County Mass Notification System is considered effective and efficient, you should not wait or rely exclusively on a call for evacuation directives. If you think you are in danger, you should evacuate immediately.

If you are directed to evacuate by emergency personnel, you should follow their direction.
