343 area code map
The 343 map is intentionally broad because the code was never an Ottawa-only assignment. It visualizes representative communities across the overlay region to show the scale inherited from 613 in 2010.

Why the map covers more than Ottawa
Ottawa is the strongest city reference, but the 343 geography extends through a much broader Eastern Ontario area that also includes centres such as Kingston, Cornwall, Belleville, Brockville and Pembroke. Area code 343 belongs to the Eastern Ontario numbering area rather than one municipality. Ottawa is the main reference point, while Kingston, Belleville, Brockville, Cornwall and Pembroke show the broader geographic reach.
The map is not a phone tracker
Ottawa is used for practical local utilities because it is the largest city and dominant search anchor, while regional pages keep the wider Eastern Ontario scope visible. A 343 number does not reveal the subscriber's current physical position. The map shows numbering geography only; ported, mobile and VoIP numbers can be used elsewhere.
What the 343 map is designed to show
The code should be read as a newer layer over an existing regional numbering map, not as an Ottawa-only code created for one municipality.
Map the service context, not invented boundaries
Ottawa is the strongest city reference, but the 343 geography extends through a much broader Eastern Ontario area that also includes centres such as Kingston, Cornwall, Belleville, Brockville and Pembroke. A useful 343 map therefore follows the real numbering scope rather than drawing a false sub-region simply because another overlay code shares the same territory.
Use the reference points as orientation
Ottawa is used for practical local utilities because it is the largest city and dominant search anchor, while regional pages keep the wider Eastern Ontario scope visible. The plotted cities are geographic anchors chosen to make the scale understandable; they are not precise locations for individual telephone numbers.
Keep numbering and physical location separate
A newer 343 caller ID is neither suspicious nor trustworthy by itself; the complete phone number and call context provide the useful evidence. A map can explain where 343 belongs in the numbering plan, but portability and internet-based calling prevent it from functioning as a caller-location tool.
