While an address is not mandatory, City of Elizabeth (COE) Alerts can be tailored to a particular area. When you enter an address, such as your home, work, child’s school or a relative’s home, the address is geocoded within the mapping system. A map system allows emergency personnel to focus their alerts down to a specific neighborhood or any entire city. If you don’t include at least one address, you may miss an important alert or receive alerts for the entire City of Elizabeth. For more information, call the Public Information Bureau at 908-820-4124.
