Reverse 911
Register with Reverse 911
The San Luis Obispo County Sheriff’s Office dispatch center has the capacity to inform the public directly by sending voice calls, text messages, and emails to registered devices in the county to inform citizens of evacuation orders, missing persons, Amber Alerts, etc.
Reverse 911 is simply another tool to assist you in an emergency, but with any system, it may not be 100% effective. Please make sure you monitor the local Emergency Alert System provided by television and radio stations, while also checking the County Office of Emergency Services for additional information during fires or other natural disasters.
2024 Update: the Sheriff’s Office has transitioned to a new system. We recommend anyone registered prior to 2024 should re-register to ensure the accuracy of your data.
Frequently Asked Questions
If you have conventional land line service to your home or office, even if it is unlisted, your number is automatically in the Reverse 911 database.
The Sheriff’s Office highly recommends when you register to add your cell phone (for calls and texts) as well as your email address to increase opportunities to receive notifications.
If you have digital or internet telephone service, you must use the self-registration portal to register your phone number and associated address to receive alerts (PO Boxes are not accepted).
Absolutely not. Your number will only be used to communicate official messages.
Use the Self Registration Portal to add cell phones to your actual address. The system will not accept Post Office boxes; it must be a real street address.
When you register, you may add multiple cell phone numbers and email addresses that can be associated with your address.
Perhaps. If your system simply requires a valid caller ID, we will get through. However, in a natural disaster or other emergency you should disable your blocking.
The system is geographically based. Use the Self Registration Portal to increase your chances of being notified properly.
