705

The 705 area code is a vital component of Ontario's telecommunications network in Canada, serving a large portion of the province and playing a crucial role in its connectivity and regional identity. Serving Central and Northeastern Ontario: Established in 1957, the 705 area code covers central and northeastern Ontario, including cities like Sudbury, Peterborough, and Sault Ste. Marie. Supporting a Diverse Region: This area is known for its natural beauty, including the Muskoka cottage country, and supports a mix of urban and rural communities with industries like mining, forestry, and tourism. Overlay with Area Code 249: To accommodate growing phone number demands, the 249 area code was introduced as an overlay in 2011, sharing the same geographic area as 705.
