Get a 365 Area Code Local Virtual Number for Toronto, Ontario

The 365 area code is part of the North American Numbering Plan (NANP) and serves the densely populated region of Southern Ontario. It was introduced as an overlay to the existing 905 and 289 area codes to meet growing demand. The 365 area code covers cities such as Toronto, Mississauga, Hamilton, Vaughan, and Oshawa.

The area operates within the Eastern Time Zone (ET) — UTC-5 during standard time and UTC-4 during daylight saving time. As an overlay code, 10-digit dialing is mandatory for local calls.

The 365 area code is located in southern Ontario, Canada, and serves as an overlay for the 905 and 289 area codes.

This region includes major cities like Hamilton, Niagara Falls, Markham, Mississauga, and Vaughan. Introduced in 2010, the 365 area code was created to handle the growing demand for new phone numbers in this densely populated and economically active area.

It supports a wide range of personal and business communication needs, especially as more organizations require multiple lines for departments, remote teams, and concurrent calls.

Since it’s an overlay, the 365 code doesn’t replace existing numbers but operates alongside them, requiring 10-digit dialing. Whether you’re running a local business or expanding into the Greater Toronto Area, a 365 number offers a credible way to establish a local presence and streamline communication without the cost of relocating.

The 365 area code was introduced in March 2013 as an overlay to the existing 905 and 289 area codes in Southern Ontario.

This region, which includes major cities like Toronto, Mississauga, and Hamilton, experienced rapid growth in population, mobile device usage, and business development, quickly exhausting the available phone numbers under the 905 and 289 codes.

The overlay model allowed existing users to keep their numbers while enabling new connections under the 365 code, without needing to redraw area boundaries. With this change, 10-digit dialing became mandatory for all local calls.

The 365 area code has since become a key part of the region’s telecommunications infrastructure, supporting expanding demand while maintaining continuity. It ensures a steady supply of new numbers for businesses and residents in one of Canada’s most dynamic economic regions.
