Locations for Area Code - 289

Area Code 289 serves the Greater Toronto and Hamilton Area (GTHA), introduced in 2001 to support explosive growth in southern Ontario. Sharing space with 905 and 365, 289 became essential as cities like Mississauga, Oakville, and Burlington expanded into economic powerhouses. While not as iconic as 416, 289 defines the suburban edge where commerce, culture, and families thrive. A call from 289 might be a startup in Hamilton, a logistics firm in Vaughan, or a homegrown restaurant in Niagara. It’s a number born from expansion, now worn with pride. For many outside downtown Toronto, 289 is the sound of ambition.
