How West Chester came to have 3 area codes

The original West Chester area code is 610, in service since 1994. As the area ran low on available numbers, overlay codes were added over the same region for new phone lines: 484 (1999) and 835 (2022). Existing numbers kept their original code — an overlay never forces anyone to change their number — which is why West Chester now uses all 3 codes and every local call is dialed with ten digits.
