How Appleton came to have 2 area codes
The original Appleton area code is 920, in service since 1997. As the area ran low on available numbers, an overlay code was added over the same region for new phone lines: 274 (2023). Existing numbers kept their original code — an overlay never forces anyone to change their number — which is why Appleton now uses all 2 codes and every local call is dialed with ten digits.
