History & Cultural Notes

Southwestern Ontario's numbering plan area has grown in layers. Area code 226 was overlaid onto the original 519 territory in 2006, with mandatory ten-digit dialing taking effect that October. A second overlay, 548, followed in 2015. By 2023, a CNA forecast projected that the combined 226/519/548 supply would exhaust by mid-2024, and the CRTC responded by approving a third overlay, 382, which entered service on June 17, 2023.

London serves as the primary city for this territory, which also reaches Windsor, Kitchener, Waterloo, Guelph, and Sarnia — an approximate population of 2.6 million across the shared numbering plan area. Windsor in particular has long been considered the historic heart of Canada's auto industry, tracing back to Ford's first Canadian plant, opened there in 1904.

That automotive legacy still shapes the regional economy today, alongside agriculture and agri-food processing, healthcare and education, insurance and financial services, and advanced manufacturing. Notably, because 382 numbers are issued only once existing supply in a given exchange runs out, most subscribers across the region still carry 519, 226, or 548 numbers even now.
