Douglas County launches DougCoAlert to replace CodeRed alerts
Douglas County’s new DougCoAlert system replaces CodeRED and requires past users to re-register, with alerts sent by call, text, email and app.
Castle Rock first responders, working with police in Lone Tree and Parker and the Douglas County Sheriff’s Office, have moved Douglas County to DougCoAlert, a free emergency notification system that replaced CodeRED and requires some residents to sign up again. The new platform launched in January 2026 and sends critical alerts by phone call, text message, email and mobile app.
The rollout ties together the Castle Rock Police Department, Castle Rock Fire and Rescue, the Lone Tree Police Department, the Parker Police Department and the Douglas County Sheriff’s Office under one countywide warning system. Parker Police has described DougCoAlert as a free countywide emergency notification service that delivers real-time public safety alerts, and Castle Pines has told residents that the new system is now available to all residents and replaces CodeRED.
The practical change for households is simple but important: if you were previously signed up for Douglas County alerts through CodeRED, you need to reregister on DougCoAlert. The system describes that step as a one-time re-enrollment, which means old registrations do not carry over automatically. The sheriff’s office’s former CodeRED page now directs users to DougCoAlert instead, underscoring that the county is moving fully to the new platform.
That shift comes as Douglas County keeps pushing other emergency-warning tools in a county that faces wildfire risk, severe weather and fast-moving public safety disruptions. County officials have publicized Stage 2 fire restrictions in unincorporated areas, and the sheriff’s office has promoted Hi-Lo sirens as an evacuation notification tool during wildfires and other major disasters. DougCoAlert is meant to work alongside that broader warning network by getting urgent information to residents through digital channels as conditions change.
For residents, the question is not whether DougCoAlert exists, but whether they are enrolled in it before the next emergency. The service is free, but it is not automatic for people who were already on CodeRED. That leaves a gap for anyone who assumes an old registration will still reach them during a fire, an evacuation or another police response. Douglas County’s message is clear: the old system is gone, the new one is live, and anyone who depended on CodeRED needs to re-register now.
