There are currently four Mississippi area codes. In 1947, area code 601 was introduced and originally covered the entire state. It wasn’t until 1997 that area code 228 was introduced to cover the southernmost parts of the state including Biloxi, Gulfport, Diamondhead and Ocean Springs. The former area code now services the cities of Jackson, Hattiesburg, Laurel and Newton. In 1999, area code 662 was established to service the northern areas of the state including the cities of Aberdeen, Clarksdale, Columbus and Tupelo. Most recently, area code 769 was introduced as an overlay, requiring residents to dial ten-digit numbers in the central parts of the state.
