Get a 905 Area Code Local Virtual Number for Mississauga, Ontario

The 905 area code is a prominent Canadian telephone area code covering the densely populated suburban region surrounding Toronto in southern Ontario. Introduced in 1993, it was split from the 416 area code due to high demand for new numbers. Today, it covers cities like Mississauga, Hamilton, Vaughan, Markham, and Oshawa. To accommodate further growth, the 905 area code has been overlaid by area codes 289 and 365. The region follows the Eastern Time Zone (ET) — UTC-5 during standard time and UTC-4 during daylight saving time.

The 905 area code is located in southern Ontario, Canada, surrounding the city of Toronto but not including it.

It covers a number of growing cities and suburban communities in the Greater Toronto Area (GTA), including Hamilton, Mississauga, Vaughan, Brampton, Markham, and Oshawa.

Established in 1993 to ease the demand on Toronto’s 416 area code, 905 has since become an iconic part of the region’s identity.

As the population expanded, overlays like 289, 365, and 742 were introduced to serve the same geographic area. The 905 region is known for its diverse communities, thriving business hubs, and rapid urban development.

Whether for personal or business use, having a 905 area code signifies a strong connection to one of Canada’s most vibrant and economically significant corridors outside downtown Toronto.

The 905 area code was introduced in October 1993 as a split from Toronto’s original 416 area code to accommodate the growing demand for phone numbers in the rapidly expanding suburbs surrounding the city.

It became the primary area code for the Greater Toronto Area outside the Toronto core, including cities like Mississauga, Hamilton, Vaughan, and Markham. As the population and telecommunications needs increased, overlays 289 (2001), 365 (2013), and 742 (2021) were added to the same region to prevent number exhaustion.

Over time, “905” became more than just an area code—it evolved into a cultural identifier distinguishing the suburban lifestyle from Toronto’s urban center. Today, the 905 area code represents a dynamic region known for its residential growth, economic activity, and diverse communities that contribute significantly to Ontario’s development.
