Emergencies can arise at any moment. Whether it’s a natural disaster, a local crime situation, or a public health threat, Reverse 911 is a public safety notification system that provides one of the most reliable ways to keep residents informed and safe during a crisis. Reverse 911 allows authorities to initiate communication by sending outbound emergency messages to residents and businesses within a specific geographic area, instead of individuals calling 911. 

While landlines are automatically included in Reverse 911 systems, cell phones, VolP, or TTY users must self-register to receive messages via text, email, or voice call. Residents must make sure their phone settings are configured to receive emergency alerts and that they sign up for your county’s Reverse 911 program.

To stay alert during emergency situations, it is important for residents to register for your county’s Reverse 911 alerts and keep personal information up to date to ensure accurate notifications.

County emergency alerts are an excellent tool to stay informed in emergency situations; however, it is also essential for residents to have a plan in place for what to do if disaster strikes.
