AlertMarin Emergency Notification System




New Emergency Notification System Upgrade

If you live, work or go to school in Marin County and are 18 and over, you may now register your cell phone or VoIP (voice over internet protocol) phone to receive emergency alerts sent by call, text, email, or smartphone application from the County of Marin.

Listed and unlisted/blocked Marin County landline phone numbers are already included in our emergency notification system. Cell phone and VoIP numbers are not included and will require your registration in our Self-Registration Portal.

Register Multiple Marin Locations

Perhaps you live in Marin, but work outside the County. Or you work and go to school in Marin, but live outside the County.  You may list up to five addresses per profile where you wish to receive notifications such as home, work, child’s school, or relatives home. Your profile may contain up to 2 SMS (text) devices, two email addresses, a TTY device, four phone numbers (including a mobile phone) and a work phone. You may also download the Everbridge “ContactBridge” application from your Apple iOS or Android device.
