CodeRED Emergency Notification System

The CodeRED Mobile Alert App is available! Click here for access.


The City of Mason City partnered with the City of Clear Lake and Cerro Gordo County to provide an emergency notification system to its residents.  The CodeRED Emergency Notification System is an ultra high-speed telephone communication service designed to deliver emergency messages and distribute information considered to be important in all or specific areas of the city or county.


This system allows us to telephone targeted areas of the City or County or the entire City or County within minutes.  It then delivers a pre-recorded message describing the situations to a live person or an answering machine in the affected area, and if necessary, including instructions requiring immediate action on the part of the recipient.


While a calling data base was created by extracting information from the Town’s computerized files and other public record sources, it is certain that not all phone numbers of residents and residential and business property owners within our incorporated limits were captured. 


If you reside or own property within the incorporated limits of Cerro Gordo County and would like to receive CodeRED emergency messages you may signup by clicking the link below.  IMPORTANT:  USE YOUR PHYSICAL ADDRESS.  DO NOT USE A POST OFFICE BOX as your address.
