Area code 581 is an overlay for 418 in eastern Quebec, Canada, covering cities such as Quebec City, Lévis, Saguenay, and Rimouski. Introduced in 2008, the 581 code was added to accommodate growing demand for new phone numbers across this historically rich and economically diverse region. Quebec City, a UNESCO World Heritage site, serves as the provincial capital and is known for its preserved colonial architecture, thriving tourism industry, and government institutions. Lévis and Rimouski contribute to the regional economy through education, shipping, and public services, while Saguenay plays a major role in aluminum production and forestry. The 581 area is predominantly French-speaking and offers a blend of traditional culture and modern infrastructure. It is home to a variety of industries including public administration, tech startups, higher education, and manufacturing. A 581 number reinforces regional presence in one of Canada’s most iconic and proudly independent cultural zones, making it ideal for businesses and individuals looking to establish credibility in Quebec’s eastern corridor.
