Where is 647 telephone exchange

Alla fine degli anni '80, tuttavia, era vicino all'esaurimento a causa della continua crescita della GTA e dell'inefficiente sistema di assegnazione dei numeri del Canada.

Il Canada non utilizza il raggruppamento di numeri come misura di rilievo. A tutti i vettori concorrenti vengono assegnati blocchi di Il problema era meno grave nel Golden Horseshoe che in altre aree del Canada da allora, come adesso, i numeri tendevano a esaurirsi abbastanza rapidamente a causa della crescita drammatica dell'area. Tuttavia, la rapida crescita del GTA e la proliferazione di telefoni cellulari, fax e cercapersone hanno reso evidente che il Golden Horseshoe aveva bisogno di un altro prefisso.

La GTA avrebbe probabilmente avuto bisogno di un'altra area codice ad un certo punto data la sua crescita esplosiva, ma la divisione potrebbe essere stata ritardata se fosse stato possibile riallocare nu.

With the amalgamation of Metro Toronto into the "megacity" of Toronto in , became the only Canadian area code to serve just one rate centre and just one city.

Many of Canada's larger cities, especially "megacities" created from mergers of previously separate cities, are split between multiple rate centres that have never been amalgamated. Toronto is an exception; it has been a single rate centre—by far, Canada's largest—since , with the merger of the historical Agincourt, Don Mills, Islington, New Toronto, Scarborough, West Hill, Weston, and Willowdale exchanges into the Toronto exchange.

The split had been intended as a long-term solution for Canada's largest toll-free calling zone. Within five years, was once again close to exhaustion.

Given Toronto's size and status as a single rate centre, numbers tended to be used up fairly quickly, so the number allocation problem was not nearly as serious as in other Canadian cities that are split between multiple rate centres. However, it was obvious that Toronto needed another area code. Splitting Toronto between two area codes—a solution adopted in the United States for cities like New York City , Chicago and Los Angeles —was ruled out because of the area's high population density and lack of a suitable boundary along which to split.

Another option was an overlay area code covering the same area as Overlays were a new concept at the time, and somewhat controversial due to the requirement for ten-digit dialling. However, Bell and other telephone companies pressed for an overlay. They wanted to spare their customers the expense and burden of having to change their numbers, which would have required en masse reprogramming of cellular telephones.

It would also have been extremely difficult to split Toronto, since it is a single rate centre. Ultimately, it was decided to implement an overlay.

However, within a decade, both and were close to exhaustion.

As of , only four Canadian area codes , , and are still single-code areas no overlay and allow seven-digit local dialing. Toronto is the centre of the largest local calling area in Canada, and one of the largest in North America. Caledon in area code is also a local call to Toronto.

The suburbs are referred to as the or the belt , and suburbanites are called ers in this use the term does not include the more distant parts of area code , such as Niagara Falls. The area code does not carry the same strong geographic associations as it disproportionately contains nomadic services such as mobile telephones and voice over IP ; an incumbent Bell land line is hard-wired to a specific location in area , postal code M.

Some have paid a premium for a true number as the code gives the appearance of a local, long-established business instead of a new entrant. In , food delivery chain Pizza Pizza obtained a Canadian registered trademark on its telephone number, , which had featured in distinctive radio advertising jingles since the s. Rapper Drake has a tattoo of the number on his rib to symbolize Toronto as his birthplace. His album picture is of him sitting on top of the CN Tower in Toronto.
