How Beaverton came to have 2 area codes
The original Beaverton area code is 503, in service since 1947. As the area ran low on available numbers, an overlay code was added over the same region for new phone lines: 971 (2000). Existing numbers kept their original code — an overlay never forces anyone to change their number — which is why Beaverton now uses all 2 codes and every local call is dialed with ten digits.
