How Windsor came to have 4 area codes
The original Windsor area code is 519, in service since 1953. As the area ran low on available numbers, overlay codes were added over the same region for new phone lines: 226 (2006), 548 (2016) and 382 (2023). Existing numbers kept their original code — an overlay never forces anyone to change their number — which is why Windsor now uses all 4 codes and every local call is dialed with ten digits.
