Area code 819 covers western and central Quebec, including cities such as Gatineau, Sherbrooke, Drummondville, and Trois-Rivières. Introduced in 1957 from a split of the original 514 area code, it spans a vast area that includes both urban centers and remote communities. In 2012, overlay area code 873 was added to meet increased demand. The region is known for its natural beauty, bilingual communities, and proximity to Ottawa. 819 remains a vital part of Quebec’s telecom network and is commonly associated with the province’s heartland.
