What is the 289 Area Code?
Established in 2001, area code 289 was one of the first overlay codes created for Ontario, Canada. It served the rapid growth around the Greater Toronto and Hamilton Area for many years. To handle the growing need for phone numbers due to the proliferation of cell phones, the 365 and 742 overlays were added later.
This telephone area code was allocated in the North American Numbering Plan to cover southern Ontario’s dense geography. The region switched to the mandatory ten-digit dialing to accommodate the overlay system as the population increased. This change ensures that every call made to a 289 number calls route correctly through modern networks. In our cloud system, you can use your local phone for office calls, customer support, and local text campaigns.
