9-1-1 (Communications)

Mission Statement

The Ontario County 9-1-1 Center, a division within the Office of Sheriff, County of Ontario, will operate under the procedures and the mission statement of that office. In addition, the Ontario County 9-1-1 Center acknowledges that it exists to serve the emergency needs of all people residing in, working in, or traveling through Ontario County—as well as to serve the communications needs of the Police, Fire, and EMS communities serving in the county. All requests for assistance, whether received via the 9-1-1-telephone system or the emergency radio system will be complied with in a professional and timely manner.

Emergency/Community Notifications

In the event of an emergency or other situation that citizens need to be informed of, Ontario County 9-1-1 utilizes an emergency / community notification system called Hyper-Reach®. The system has been used to advise of water main breaks, lost children, and dangerous conditions, as well as many others. We can choose an address, address range, or geographical area, and send a message to everyone selected at a rate of up to 10,000 phone numbers per hour. If you receive one of these calls, please follow the directions given and do not call 9-1-1 unless you have an emergency or are directed to do so.

The Hyper-Reach® system uses the phone company's database of landline (wired) telephone numbers provided by those telephone companies that serve Ontario County. If you utilize a TDD / TTY or if you use a wireless (cell) phone, digital (VoIP) phone, or a service like Magic Jack® and no longer have a regular wired home phone, please consider registering your phone number to receive these important messages, click the link above.

According to 10 years of CDC surveys, the percentage of households with landlines goes down about 4% each year. If that trend continues, less than 10% of people will have a landline at home by 2027, some agencies have even seen as much as a 15% decrease in landline phones.
