Reverse911 is an emergency warning tool used to make rapid emergency telephone notifications to residents and businesses in precise geographic areas. Reverse911 will be used by Butler County emergency officials, during emergencies only, to deliver incident-specific information or potentially life-saving instruction to those in the affected area(s).
Reverse911 integrates mapping technology with phone databases, and will call listed and unlisted landline telephone numbers for Butler County residences and businesses.
Cellular phone numbers are not automatically included in the system database, nor are Voice Over Internet Protocol (VoIP) phone systems. If you would like to receive these emergency telephone notifications on your cellular or VoIP phone, you must first register these phone numbers.
