Cambridge to Utilize CodeRED Mobile Alert App for Mass Notification

Residents can now receive emergency alerts via their iPhone or Android device


Residents with smartphones can now download an app that will allow them to receive CodeRed alerts. The CodeRED Mobile Alert app will show alerts issued by the City of Cambridge when it uses the CodeRED system to make phone calls and/or send text messages and emails about emergencies or other major incidents in the City.

Cambridge Police Commissioner Robert C. Haas said the new app will serve as an additional tool to help inform the community and visitors about important information that may impact their safety.  "The app works similarly to our current CodeRED system.  If you have the app downloaded and are in the affected area of the alert, a notification will be sent through the app to alert you of the issue,” Haas said.

Residents who have subscribed to CodeRED alerts will continue to receive voice calls, text messages and emails. 

“The app may also be useful when a Cambridge resident is traveling to another city or state that also uses the CodeRED system, because they will receive any community or emergency alerts from that specific area as well.  It’s just one extra way to stay safe when you’re away from home,” Haas said.  This additional outlet for Cambridge to communicate time-sensitive messages to residents and visitors is at no additional cost to the current contract CodeRED contract with Emergency Communications Network.

Residents with iPhones and Android smartphones are encouraged to download the app to begin receiving notifications from the City of Cambridge.  The app is available for a free download on the iTunes Store and Android Market.  For more information, or to download the CodeRED Mobile Alert app, visit
