GOLDEN, Colo. -- Jefferson and Broomfield Counties will test their CodeRED emergency alert system Tuesday.

Starting at 9 a.m., a test message will be sent to all landlines in both counties, as well as registered cell phones and emails. Residents in portions of Adams and Clear Creek Counties may also receive the notifications if they are in CodeRED notification area.

"This process is expected to take several hours due to the large number of notifications," according to Arvada Police. "The CodeRED system is used by emergency services agencies in Jefferson and Broomfield counties to help disseminate information regarding critical incidents."

To register your cell phone and/or email, sign up on the CodeRED website.

Here's how to get emergency alerts in other counties:


Adams County uses the CodeRED notification service to contact home landline phone numbers within the geographical jurisdictions of the City of Bennett, the City of Brighton, Commerce City, the City of Northglenn, Unincorporated Adams County, and the Adams County portion of Strasburg. This system can also send alerts to cell phones, but residents personally need to register their cell phones into the system. Residents must register under the address in which they’d like to receive notifications. Reregistering the same cell phone number under different addresses (i.e. work, school, and home) is also possible. Register your cell phone here.


Arapahoe County said residents and businesses with land line phones are already listed in Arapahoe County's 9-1-1 database, and are therefore automatically included in the notification system. You may sign up to register additional mobile devices here.


Aurora allows residents to register their preferred means of communication -- cellular phone, text message, email or all three. Learn more here.


Broomfield city and county uses the CodeRed system to send out emergency alerts. Home phone numbers are entered into the 9-1-1 database and dialed automatically.  CodeRED will not call a cell phone or VoIP system phone unless it has been registered. Register here.


Boulder County has a mass notification system that is used to notify residents about imminent threats to health and safety such as the need to evacuate due to a wildfire, or take other appropriate actions in the event of a flash flood or other critical police activity. Learn more and register here.


Denver says it uses the Swift911 Emergency Notification System to alert residents to emergency situations like police activity, severe storm warnings, road closures, water problems and evacuations that are occurring in their area. Learn more and sign up here.


Douglas County allows residents to sign up for emergency alerts and register their gate codes through the CodeRED system.


Elbert County also uses CodeRED for reverse emergency notification calls, weather warning notifications calls and emergency community updates. Learn more and sign up here.


Gilpin County also uses CodeRED to deliver pre-recorded information to either targeted areas or the entire county. Residents may register two phone numbers here.


In Jefferson County, the CodeRED emergency notification system is used to citizens with warnings of flood, fire, tornadoes, chemical spills, or dangerous suspects.

CodeRED uses the county’s 911 database to call all listed and unlisted land lines. CodeRED also calls a database of mobile phone and VoIP* numbers if you opt in. To register, visit the CodeRED phone registry.


Larimer County's Emergency Alert System allows residents to sign up to receive alerts on your mobile phone in the form of texts, voice calls and emails. You can register multiple devices (cell phones, emails, etc) and sign up for several different locations that are important to you (i.e. your child’s school or your elderly parent’s house)


Weld County will let you sign up for several different alerts including a list of most wanted fugitives, recent arrests and EOC alerts. Signing up for the EOC alerts will get you updates when emergency and disasters are happening.


Thornton residents may sign up for the T-Alert system and an emergency notification system.

Check with your city and/or county, to register your cell phone.
