What is CENS? 

CENS is the Community Emergency Notification System operated by Maricopa County. The system is designed to rapidly notify an affected area of an emergency by sending a recorded message through the telephone system.

Will CENS work with cell phones or VoIP phones? 

Cell and VoIP phones are not part of the 911 database.  You now have the option to register your Cell or VoIP phone with the CENS system.  You will only receive CENS notifications based on the address you provide for your Cell and or VoIP phone. 

Please follow this link to register your Cell or VoIP phone:
