Locations for Area Code - 343

Area Code 343 is an overlay for eastern Ontario, including Ottawa, Kingston, and the Rideau corridor. Introduced in 2010 to supplement 613, it has steadily grown into a local standard. In a region marked by federal power and historic charm, 343 represents new energy. A call from 343 might come from a Parliament Hill staffer, a researcher at Queen’s, or a creative mind in the ByWard Market. Though newer, it stands proudly beside its older sibling, bridging old institutions with new ideas. In the capital region, 343 means you’re part of the conversation, and it’s only getting louder.
