Register Your Cell Phone or VoIP home phone For Emergency Notifications in Santa Cruz County. Sign up to have your cell phone and/or VoIP home phone included in the new Emergency Notification system used by Santa Cruz Regional 9-1-1 personnel to send important messages to residents and businesses within Santa Cruz County.

If you have Comcast, Vonage or any other VoIP phone provider, and you have registered your home address with that provider, your calls to 911 should be routed correctly. However, in order for the reverse 911 system to work for you, you will need to register it with Santa Cruz Regional 9-1-1.
