Why Metro Columbia Has 2 Area Codes

When a region uses more numbers than one code can hold, new codes are overlaid on the same territory rather than forcing anyone to change numbers. Metro Columbia now uses 803 and 839: same neighborhoods, ten-digit dialing, and every one of them covered by its own guide above.
