The City of Thornton uses the CodeRED Emergency Notification System to warn residents of potential life safety dangers and other emergencies like wildfires, floods, criminal activity, evacuations, and water utility outages. The system has the ability to send alerts to individual households, neighborhoods, or the entire city based on the risk to the community, however it requires residents to sign-up. The alerts come in the form of a telephone call, text message, email, social media, mobile alerts to the CodeRED app, and may include the use of the Federal Integrated Public Alert and Warning System (IPAWS). There are three (3) easy ways to sign up for CodeRED:

• visit the CodeRED signup page
• text THORNTONCO to 99411
• Call the Thornton Dispatch non-emergency line at 720-977-5150

If you wish to have your telephone number removed from the emergency telephone notification list, please contact the Thornton Emergency Communication Center at 720-977-5150. You may send the request through My Thornton, however you will be contacted by telephone or direct email verifying your request.

Please be ready to provide the following information:

• Full name (first and last)
• Address
• Telephone number

With the exception of emergencies, the police department rarely issues telephone notifications after 9:00 PM or before 7:00 AM.

Caution! If you remove your name and telephone number from the emergency notification system, you will not receive any notifications from the City concerning true emergencies such as severe weather/storm notifications, emergency police and fire situations or any other type of emergencies in your area.

To have your number removed from the “blocked” list contact the Thornton Emergency Communication Center at 720-977-5150.  Please provide your full name, address and telephone number.
