Emergency Alerts Notification System

Sacramento Alert

The Sacramento County Office of Emergency Services, in partnership with Yolo and Placer County emergency agencies, cooperatively manage a state-of-the-art emergency alert system known as Sacramento Alert.  Sacramento Alert is a web-based application that enables authorized County, City, and Special District public safety officials to disseminate public safety information rapidly and efficiently to the residents of Sacramento.

Sacramento Alert utilizes "reverse 911" data and technology as well as contact information provided by citizens through our Citizen Opt-In portal.

To better ensure the receipt of public safety alert and warning notifications, residents are encouraged to log onto the Sacramento Alert Citizen Opt-In portal below and provide their preferred and most optimal contact information through which they would like to receive notifications.  This can include phone numbers as well as email addresses and TTY device information. 

All information in the Self Registration Opt-In Portal will be kept strictly confidential.

Residents will only receive alerts that are critical and time-sensitive, including: flooding, levee failures, severe​ weather, disaster events, unexpected road closures, missing persons, and evacuations of buildings or neighborhoods in specific geographic locations.

The system, known as Rave Mobile Safety via the Smart911 portal, serves the entirety of Sacramento County, and is funded by the Homeland Security Grants Program (HSGP) and supported through​ the Sacramento County Office of Emergency Services.
