How Longview came to have 2 area codes
The original Longview area code is 903, in service since 1990. As the area ran low on available numbers, an overlay code was added over the same region for new phone lines: 430 (2003). Existing numbers kept their original code — an overlay never forces anyone to change their number — which is why Longview now uses all 2 codes and every local call is dialed with ten digits.
