Mississippi Area Code Overlays
(601 and 769)


Mississippi is currently using four area codes. Mississippi has had two area code splits and utilizes one area code overlay plan, often called an overlay complex.

Area code 601 originally covered all of Mississippi when it was established in 1947. This was sufficient for more than fifty years. It was not until 1997 that Mississippi experienced sufficient growth in population and telephone use to need an additional area code. It was at that time that area code 601 was split to form area code 228. In 1999 area code 601 was split again to form area code 662. In 2005 area code 769 was put into use as an overlay of area code 601.

Today area code 601 covers central Mississippi including Jackson and Hattiesburg. Area code 228 covers southern Mississippi including Biloxi, Gulfport and Pascagoula. Area code 662 covers northern Mississippi including Columbus, Greenville and Tupelo.
