Where is Toronto?

Toronto is the capital of the province of Ontario, located in southeastern Canada. As the capital city of Ontario, Toronto has a population of approximately 2.9 million, according to the latest update. Area code is crucial in organizing and managing telecommunications services in highly populated areas like Toronto. The original 416 area code was introduced in 1947. Later, 647 and 437 were added as overlays of 416.

Toronto has experienced significant economic growth, particularly in the business sector. It is a central hub for business, finance, art, culture, and tourism. The city’s area code enables companies to communicate seamlessly with their diverse customer base.

Area Codes in Toronto, Canada

The introduction of area codes in Toronto was primarily due to the growing demand for telephone services as the city’s population and telecommunications infrastructure expanded. The area codes 416, 437, and 647 serve Toronto.

  • 416 area code: The 416 area code of Toronto was introduced in 1947 as one of the 68 original area codes as part of NANP. At the time, it was the only phone code that covered the entire metropolitan area of Toronto. You can get 416 phone numbers in Canada from a reliable business phone service provider.
  • 647 area code: The 647 area code was introduced in 2001 as an overlay due to the growing population and demand for phone numbers. It was the 7th area code in the province of Ontario and serves the city of Toronto and surrounding areas, including the downtown core, Etobicoke, New York, and Scarborough.
  • 437 area code: The 437 phone code was introduced as an additional overlay in 2013 to meet the demand for telephone numbers. Like 647, it serves the same geographic area and supplements the existing supply of phone numbers.


942 is a new area code approved by CRTC (Canadian Radio-television and Telecommunication Commission) for the Greater Toronto Area in Canada. It will go into service on April 26, 2025, as an overlay phone number for the city and surrounding suburbs. It will be the fourth phone code and join existing Toronto area codes 416, 647, and 437.
