Information About Postal Codes and Zip Codes
Area codes 705 and 249 are telephone area codes that cover most of northeastern and central Ontario in Canada. 705 was initially created in 1957 by the North American Numbering Plan (NANPA) from portions of the area covered by area codes 613 and 519. Area code 807, covering northwestern Ontario, was split from area code 705 in early 1962.
On March 19, 2011, area code 249 was added as an overlay code. In addition, since this date all calls require ten-digit dialing.
The incumbent local exchange carriers in 705/249 are Bell Canada, Northern Telephone, Ontera, East Link and some municipally-owned carriers.
