Area codes 819 and 873, Telephone area codes in central and western Quebec, Canada
Area codes 819 and 873 serve central and western Quebec, covering regions like Outaouais, Abitibi-Témiscamingue, and the Hautes-Laurentides, along with cities such as Trois-Rivières, Drummondville, and Sherbrooke. Both codes operate together across the same territory, with new phone numbers assigned the 873 code while existing ones retain 819.
The 819 code was created in 1957 when the original 514 code was limited to Montreal, bringing telephone service to previously unserved territories. The 873 code was later introduced to accommodate increasing demand for new phone numbers across the same region.
The dual code system reflects how telecommunications adapted to serve both French and English speakers throughout the region, from city centers to remote areas.
People in this region may encounter phone numbers starting with either 819 or 873 even though both codes serve the same geographic area. Understanding that both numbers work for the same places helps avoid confusion when calling locally or sharing contact information.
The region includes part of Canada's capital area, where the Ontario-Quebec border creates a distinct telecommunications boundary between Ontario's 613 code and Quebec's codes. This geographic split is notable because it shows how phone networks align with provincial boundaries in this major urban center.
