As reported previously, the 416 area will soon share the city with another code, 437, and the suburban 905 zone will add the 365 area code. Starting tomorrow Bell, Rogers, Telus and others can begin handing out the 437 area code in Toronto alongside 416 and 647 and the 365 area code in the 905-289 region. It may however take a bit longer than that because there a few old numbers left. “These new area codes reflect the growing use of cell phones and other mobile devices,” says Glenn Pilley. Mr. Pilley has the fascinating title of Canadian Numbering Administrator and he points out that adding a new area code can create more than seven million new phone numbers.
