The City of Colleyville uses the CodeRED Emergency Notification System - an ultra-high-speed telephone communication service for emergency notifications. This system allows Colleyville Office of Emergency Management to telephone all or targeted areas of the city in case of an emergency situation that requires immediate action, such as a severe weather notice, missing child, or evacuation notices.

IMPORTANT NOTE: When answering the CodeRED call, you must say something such as "Hello," for the message to play.
