How Shreveport came to have 2 area codes
The original Shreveport area code is 318, in service since 1957. As the area ran low on available numbers, an overlay code was added over the same region for new phone lines: 457 (2025). Existing numbers kept their original code — an overlay never forces anyone to change their number — which is why Shreveport now uses all 2 codes and every local call is dialed with ten digits.
