History of Area Code 337
Area code 337 was established in 1999 when Louisiana split area code 318. The new code served southwestern and south-central Louisiana, including Lafayette, Lake Charles, and surrounding communities. The split provided additional telephone-number capacity as the region needed more lines.
Area code 457 later became an overlay for area code 337. An overlay adds a second area code to the same geographic region instead of dividing the region, so both 337 and 457 numbers can identify telephone lines in the area. The overlay also requires ten-digit dialing for local calls.
