Get a 343 Area Code Local Virtual Number for Ottawa, Ontario

The 343 area code is part of the North American Numbering Plan (NANP) and serves Eastern Ontario, Canada. It was introduced as an overlay for the 613 area code to support the growing need for new telephone numbers. Key cities served include Ottawa, Kingston, Belleville, Cornwall, and Brockville.

The 343 area code functions alongside 613 in an overlay arrangement, requiring 10-digit dialing for local calls. Eastern Ontario is in the Eastern Time Zone (ET) — UTC-5 during standard time and UTC-4 during daylight saving time.

The 343 area code is located in eastern Ontario, Canada, and overlays the existing 613 area code. It serves major cities such as Ottawa, Kingston, Cornwall, and Brockville.
Introduced in 2010, the 343 area code was added to accommodate the rising demand for multiple phone numbers in the region. This area is home to a mix of residential neighborhoods, thriving businesses, and Canada’s federal government offices.

Because 343 is an overlay, both 343 and 613 numbers are used in the same geographic region, and 10-digit dialing is required for all local calls.

Whether you’re setting up a business line or need multiple phone numbers for different departments, the 343 area code offers flexible options. It’s ideal for organizations and individuals in eastern Ontario who want a local presence or need to expand their communications network efficiently.

The 343 area code was introduced in May 2010 as an overlay to the 613 area code in eastern Ontario, Canada. The 613 area code, one of the original North American area codes established in 1947, had served the region for decades.

However, with the rapid growth of mobile devices, internet services, and businesses requiring multiple phone numbers, the available combinations under 613 began to run out.

To prevent number exhaustion, the Canadian Radio-television and Telecommunications Commission (CRTC) approved the introduction of 343 new numbers. Rather than splitting the region, the overlay allowed both area codes to coexist, requiring 10-digit dialing for local calls.

This solution ensured a smooth transition while maintaining existing phone numbers. Today, 343 supports a wide range of users across eastern Ontario, including Ottawa, and remains essential to meeting the region’s evolving communication needs.
