Area Code 604 is the original code for British Columbia, introduced in 1947 and long associated with the Lower Mainland, especially Vancouver. Even as overlays like 778 and 236 came along, 604 retained its elite status. A 604 number suggests roots in a global city, whether from a film studio, a corporate tower, or a coffee shop in Kitsilano. It’s shorthand for urban West Coast living: creative, cultured, and cosmopolitan. In Vancouver, 604 isn’t just a number,it’s a name, a brand, a calling card.
