CodeRED is an emergency notification system that allows the City to send emergency notifications to subscribers via email, text and phone calls.  This service will be used in the event of emergencies affecting the City, such as snow emergencies, evacuations, large-scale water outages or other significant service disruptions.

We encourage anyone who lives, works, attends school, owns property or is otherwise interested in being informed about emergencies connected to one or more Cambridge addresses to enroll online with CodeRed using the link below.    Once you enroll you should set up an account so you can self manage it.

Because of this, it is vitally important that members of the community use the CodeRED online subscription page to add their home phone (land line), cell phone numbers, email addresses, and VoIP-type phone numbers. Please use only a proper Cambridge street address number and street name with suffix (e.g., 100 Cambridge St) when entering your Cambridge address. Post Office box numbers or addresses outside of Cambridge cannot be accepted.

If you need assistance enrolling online you can download the Registration Form below and mail it to CodeRED Enrollment, Cambridge Emergency Communications, 125 6th St, Cambridge MA 02142. You can also call 617-349-9490 for more information, or to leave information sufficient for us to enroll you.
