Cambridge Alert Network

Cambridge uses an emergency notification system to send emergency alerts 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 sign-up for notifications using the link below.

Include your home phone (land line), cell phone number(s), email address(es), 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 or require additional information, please call 617-349-9490 for more information.

Residents are encouraged to sign up to receive notifications for their neighborhood as well as the "CITYWIDE" group.  The groups are:

• Cambridge PD: CITYWIDE

Notifications will come in three forms:

1. Resident Alerts - The most important and timely notification from the police will be labeled as such and sent to the affected neighborhood(s) and the "CITYWIDE" group.  These alerts will typically be sent within 12 hours of the incident during the following scenarios:
   • Threats to Public Safety
   • High Profile Incidents
2. Advisory - This type of notification will be primarily used to share important information with the community and will be sent to affected neighborhood(s) and the "CITYWIDE" group if the information affects the entire community.  Typically, these notifications will be sent following the monthly BridgeStat release, and will include information about the following:
   • Significant Incidents and Follow-ups
   • Crime Patterns Identified in BridgeStat
3. Neighborhood Info - Notifications will be sent to inform individual neighborhoods about neighborhood-specific information that does not apply to the city as a whole, such as:
   • Neighborhood Meetings
   • Other Neighborhood-Specific Announcements

Tip411 also allows people to text anonymous crime tips to the police, helping provide valuable information to investigators and make our community a safer place.

The City and Cambridge Police Department has joined Nextdoor --- a private social network for neighborhoods to provide important news, services, programs, free events, and notifications to Nextdoor users residing within the City.

Residents will be able to engage with each of the City and police department’s posts with questions and comments, as well as send private messages to staff.
