Find any 705- phone number in Ontario

The 705 area code covers most of the province of Ontario, Canada. Originally, this area code was implemented in October, 1957, as part of the North American Numbering Plan (NANP). The NANP is a system administered by the North American Numbering Plan Administration (NANPA) that assigns each telephone service its own unique area code. This area code remains the most populated area code in the province of Ontario.

Area codes were developed in order to allow for a single number for long-distance calls, no matter the area in which one was calling. It also allowed for population growth in different areas and increased use of phone services. The 705 area code is split into 15 regional rate centres, including the Sault Ste. Marie and Sudbury regions. It is also bordered by area codes 807, 226, 613, 519, 548, and 742.
