Reverse 911 Emergency Notification System

The City of Dallas Reverse 911 Emergency Notification System is used to rapidly send telephone notifications to residents and businesses in an affected area in the event of an emergency. The system will automatically call listed and unlisted telephone numbers (including TTY/TDD) within the area affected by the emergency and deliver a recorded message. If phone lines are busy, the system will attempt to redial those telephone numbers to make contact. If an answering machine picks up the call, the emergency message will be left on the machine. The City of Dallas assumes no responsibility if an emergency message cannot be delivered or is not received.

Cellular phone numbers are not automatically included in the system database, nor are Voice over IP (VoIP) phone systems. If you would like to be contacted on your cell or VoIP phone, you must register these phone numbers.

Please note that the service being offered is for City of Dallas residences and businesses ONLY.

To ensure that you are notified about emergency events affecting your area, citizens who wish to receive the emergency notification on a cellular or Voice over IP (VoIP) phone number should register.
