Area code 416 is one of Canada’s original area codes, assigned in 1947, and serves the core of Toronto, Ontario. Once covering much of southern Ontario, it was narrowed over time to the city proper. Due to high demand, it was overlaid with 647 in 2001 and 437 in 2013, making ten-digit dialing standard. Despite this, 416 remains the most iconic and sought-after area code in Toronto, often associated with long-established businesses and cultural identity. It symbolizes urban prestige and is a prominent part of Toronto’s branding and legacy.
