CodeRED Emergency Notification System

What is the CodeRED Emergency Notification System?

CodeRED is a free emergency notification service provided to all residents and businesses in Lone Tree. 

This service will notify you of emergency situations through phone calls, text messages, emails and the CodeRED mobile alert app. 


Some Lone Tree residents may already be signed up for a previous system that all jurisdictions within the county used. County and municipal agencies are no longer using that system. Though contact information was transferred to the new system, it is suggested all residents and businesses sign up for the new system to ensure they are included in this important effort. 

Like the former system, CodeRED alerts may be implemented in situations such as police activity in the area, an Amber Alert, wildfires or other emergency incidents. However, the system does not include weather alerts. The City of Lone Tree encourages residents and businesses to stay tuned to weather radios and local media for information during severe weather.

How do I Sign Up for CodeRED Notifications?

In order for CodeRED to perform at its best, it needs an accurate database of contact information, associated with addresses. That’s why the public’s help is needed. To ensure your information is included in this database, you must sign up. Registering is free.

Required information includes: First and last name, street address (no P.O. Boxes), city, state, ZIP code and primary phone number. All data will be kept confidential.

Residents can also sign up using cell phone numbers and emails, because dispatch centers can also use CodeRED to send messages via text message or email. Signing up allows residents to set their contact preferences. Should residents move, they will need to register again with the new address.
