Area Code 450 surrounds the island of Montreal, covering cities like Laval, Longueuil, and the South Shore suburbs. Introduced in 1998, it became essential as Montreal’s influence pushed outward. Whether it’s a manufacturing hub, a booming suburb, or a satellite office for a multinational, 450 is where urban meets residential. It’s the commuter’s code, the entrepreneur’s base, the family’s start. A 450 call is distinctly Québécois, grounded and thriving. It may not carry downtown’s prestige, but in the broader Montreal area, 450 is identity. It signals community, growth, and a life just outside the core.
