What is Reverse 911?

San Luis Obispo County officials are able to inform the public of an emergency by utilizing an emergency telephone notification system, known as Reverse 911. Emergency officials can notify residents and businesses in a designated area of an emergency and actions they may need to take.

The Reverse 911 system is managed by the San Luis Obispo County Sheriff’s Office and can be used county wide. Although the system is used primarily for disasters which require the public to act, it may be used in other emergency such as high-risk missing persons.

How to Register

This system utilizes the 9-1-1 telephone database and therefore can contact listed and unlisted land line telephones. If you have a Voice over IP (VoIP) or cellular telephone that you would like to be notified on, you must self-register those telephone numbers the San Luis Obispo County Sheriff’s Office.

If you are unable to complete the online registration via the Sheriff’s Office, you may print and fill out a hard copy of the form here and return it to our office.
