Area code 873 is an overlay for area code 819 in western Quebec, Canada. It was introduced in 2012 to support number growth across a large region that includes cities like Gatineau, Sherbrooke, and Val-d'Or. This area includes both urban centers and vast rural stretches, with a strong presence in tourism, mining, and public administration. Gatineau, directly across the river from Ottawa, is part of Canada’s National Capital Region and plays a vital role in federal government operations. Sherbrooke is a major university town and research hub, while northern parts of 819/873 include mining operations and Indigenous communities. Having a number in the 873 overlay ensures full geographic coverage while maintaining connectivity in a culturally rich and economically diverse part of Quebec. It’s ideal for businesses that serve both government and private sector clients, or for individuals who want local reach across one of Canada’s more expansive regions.
