Alert San Diego (Reverse 911) Information

Alert San Diego (Reverse 911)

The County of San Diego, in partnership with Twenty First Century Communications, Inc., has instituted a regional notification system that will be able to send telephone notifications to residents and businesses within San Diego County impacted by, or in danger of being impacted by, an emergency or disaster.

This system, called AlertSanDiego, will be used by emergency response personnel to notify those homes and businesses at risk with information on the event and/or actions (such as evacuation) we are asking them to take. The system utilizes the region's 9-1-1 database, provided by the local telephone companies, and thus is able to contact landline telephones whether listed or unlisted. It is TTY/TDD capable. Because the system uses the 9-1-1 database, only landline numbers are in the system. If you have a Voice over IP (VoIP) or cellular telephone and would like to be notified over that device, or if you would like an email notification, you must register those telephone numbers and/or email address for use by the system.

Cell phones can be registered at:

Individuals who do not have a way to register themselves online can also print out this form (click here) and mail it to the Oceanside Police Department, who will enter the information on the website.
