Area code 343 falls within Ontario. Area codes are assigned geographically, but because of number portability a phone number does not always stay in the region it was originally issued for.

The approximate centre of this numbering area is located at latitude 44.95518 and longitude -76.08718, placing it within Ontario. Coordinates are averaged from the associated city data and should be treated as a general reference point.

Area code 343 is one of hundreds of codes in the North American Numbering Plan. Codes are opened, split and overlaid by numbering administrators as demand changes, so city and region associations can shift over time.

Because of number portability, the current location of a phone number may differ from the area shown here. This page describes the area code assignment, not the physical location of an individual subscriber in Canada.
