Origin Story
Area code 343 was created as an overlay for the original 613 area code, which was one of the 86 original North American area codes assigned in 1947. By the mid-2000s, the proliferation of cell phones, pagers, and fax lines in the Ottawa and Eastern Ontario region led to a critical shortage of available phone numbers. The Canadian Radio-television and Telecommunications Commission (CRTC) approved the new overlay code in 2008 to provide numbering relief. Area code 343 officially went into service on May 17, 2010. Unlike a geographic split, an overlay allows both 613 and 343 to serve the same area, meaning all new numbers could be assigned the 343 code while existing 613 numbers remained unchanged. This solution ensured seamless continuity for businesses and residents. The region's growth was so rapid that a third overlay, area code 753, was activated in March 2022, and a fourth, 871, has been reserved since May 2025, underscoring the area's ongoing economic and demographic expansion.
