How McKinney came to have 4 area codes
The original McKinney area code is 214, in service since 1947. As the area ran low on available numbers, overlay codes were added over the same region for new phone lines: 972 (1996), 469 (1999) and 945 (2021). Existing numbers kept their original code — an overlay never forces anyone to change their number — which is why McKinney now uses all 4 codes and every local call is dialed with ten digits.
