Area code 343 is an overlay for 613 in eastern Ontario, Canada, serving cities such as Ottawa, Kingston, Cornwall, and Brockville. Introduced in 2010, the 343 code helps meet the growing demand for mobile and business lines in Canada’s capital region. Ottawa, the nation’s capital, is a major center for federal government agencies, high-tech industries, and bilingual public services. The area is also home to universities like Carleton and the University of Ottawa, fostering a highly educated workforce. Kingston, a historic city on Lake Ontario, supports military, academic, and tourism sectors. While 613 carries historical cachet, 343 is widely accepted and increasingly common.
