647 Area Code

Published In

The area code 647 is assigned to the city of Toronto in Ontario (Canada) in the North American Numbering Plan (NANP). It is an overlay to the area code 416 which was introduced in the year of 1947 by the American Telephone & Telegraph Company (AT&T). With the increase in the number of users, area code 647 was introduced in the year 2001.

Some people might not be aware of the fact that there is another area code of 437 introduced in the year 2013 as an overlay to area code 647. All three area codes serve the same NPA (Numbering Plan Area). As an overlay to 437, area code 387 has already been reserved for the city’s future use. But the predictions say that it might not be required to be introduced until the year 2025.

There have been some changes in the Toronto Area code since its inception. The prime reason for introducing these changes is the consumption rate of the region. Toronto is one of the biggest cities in Canada and the hub of businesses in the province of Ontario hence the rate of exhaustion of phone numbers is still among the highest in the country.

Since the introduction of an overlay area code 647, it has served as a model of preferred solution for the area code exhaustion issue. It provides the carriers with an easy workaround for the number allocation problem. Till 2019, there were only four area codes in Canada that did not have any overlay area code and were still using a seven-digit local dialing system.

647 area code is similar to others is used in the ten-digit dialing system used in Canada. It means that you need to dial the area code even if you are dialing a local number within Toronto.
