Area Code 365 serves the Golden Horseshoe region of southern Ontario, introduced in 2013 to accommodate booming cities like Hamilton, Markham, and St. Catharines. As an overlay to 905 and 289, it reflects the fast-moving transformation of suburban Ontario into a diverse, urbanized force. Whether it’s a logistics firm near Pearson, a digital agency in Vaughan, or a family-run shop in Niagara, 365 powers the everyday engine of Ontario. In a region where growth never stops, 365 marks your place in the future. It may be new, but it speaks to hustle, diversity, and momentum.
