How Sanford came to have 3 area codes

The original Sanford area code is 407, in service since 1988. As the area ran low on available numbers, overlay codes were added over the same region for new phone lines: 321 (1999) and 689 (2019). Existing numbers kept their original code — an overlay never forces anyone to change their number — which is why Sanford now uses all 3 codes and every local call is dialed with ten digits.
