Williamson County is encouraging local residents to voluntarily provide emergency notification phone numbers in order to expand effectiveness of our REVERSE 911 Emergency Notification System.

The Emergency Notification System is a mapping software system that will notify citizens of emergencies or any important information in your area. This might be something simple as a message about recent police activity in for your neighborhood to critical emergencies like amber alerts or evacuations.

We are asking you to provide additional contact information as it relates to your home address. The next few screens will ask you for your street name and your house number. Then you will be able to enter several phone numbers that you wish to be contacted at. Once the information has been submitted, someone from the County will contact you to verify this information.

To begin, enter your street address or part of your street address. Do not enter unit (apt/suite) number, city, or state. If your address appears in the search results, click it to continue.

e.g. - "1320 West Main"
