Area code 647 is an overlay for Toronto, Ontario, introduced in 2001 to complement the original 416 area code due to the city’s booming population and increasing demand for phone numbers. It covers the entire city of Toronto and shares the region with overlays 437 and 365. Known for its use with mobile phones and new business lines, 647 has become a standard part of the city’s telecommunications landscape. Toronto, as Canada’s largest city, is a hub for finance, tech, media, and multiculturalism. While 416 holds historical prestige, 647 is firmly embedded in modern Toronto’s identity.
