Mississippi has 5 active area codes as of 2026, covering the state through a mix of original 1947 assignments, geographic splits, and modern overlays. This guide walks through the full list, which regions each code serves, the order they came online, and where new codes are most likely to land next.
The Short Answer
Mississippi currently has 5 active area codes in service. The count reflects a combination of population growth, the rise of mobile lines, and the way modern numbering allocates blocks — every line activated, whether a cellphone, a business desk line, a VoIP number, or a connected device, consumes a slot in the pool.
By population, Mississippi ranks #34 nationally with roughly 2,943,045 residents as of the most recent estimates. That puts the state’s area code count in line with its population peers — denser, faster-growing states need more codes; smaller states need fewer.
The Full List of Mississippi Area Codes
The active area codes serving Mississippi are listed below, in numerical order. Where a code is an overlay or a split-off from an earlier code, that relationship is noted.
- 228 — Gulf Coast (Biloxi, Gulfport, Pascagoula)
- 471 — Northern Mississippi (Tupelo, Oxford, Southaven, Starkville) (overlay of 662)
- 601 — Central and southern Mississippi (Jackson, Hattiesburg, Meridian)
- 662 — Northern Mississippi (Tupelo, Oxford, Southaven, Starkville)
- 769 — Central and southern Mississippi (Jackson, Hattiesburg, Meridian) (overlay of 601)
How Mississippi’s Area Codes Grew Over Time
Mississippi received its first area code, 601, when the North American Numbering Plan launched in 1947. That single code initially covered the entire state, and subsequent splits and overlays narrowed it over the decades that followed.

Browse Mississippi Area Codes →- 1947 — 601 assigned as Mississippi's sole area code at the launch of the North American Numbering Plan, covering the entire state.
- 1997 — 228 split off from 601 for the Gulf Coast region, serving Hancock, Harrison, and Jackson counties (Biloxi, Gulfport, Pascagoula).
- 1999 — 662 split off from 601 for the northern half of Mississippi, including the Memphis-area counties and the cities of Tupelo, Oxford, and Starkville.
- 2005 — 769 activated on March 14 as Mississippi's first overlay, joining 601 across central and southern Mississippi and making ten-digit dialing mandatory in that region.
- 2026 — 471 activated on January 30 as an overlay of 662 in northern Mississippi, the state's second overlay complex.
Why Mississippi Has Multiple Area Codes
A single area code can hold roughly 7.9 million possible phone numbers in theory — 792 valid central office codes (the second three digits) multiplied by 10,000 line numbers each. In practice the usable count is lower, because blocks of numbers are reserved, withheld, or assigned in bulk to carriers that may never fully use them. When the pool of available numbers in an area code falls below the threshold the North American Numbering Plan Administrator (NANPA) tracks, the state requests relief, and either a split or an overlay is approved.
Mississippi’s population of roughly 2,943,045 residents would, on its own, fit comfortably inside a single area code’s capacity. The reason 5 codes are needed instead is that every adult typically carries at least one mobile line, many households have multiple lines per person, businesses concentrate phone numbers at extreme density, and connected devices, VoIP services, and second-line apps all draw from the same pool. The math compounds quickly.
Mississippi Area Codes by Region
Central and southern Mississippi (601, 769): Jackson, Hattiesburg, Meridian, Brookhaven, and the bulk of the state's population. 601 is the original from 1947; 769 was added as an overlay in 2005.
Northern Mississippi (662, 471): Tupelo, Oxford, Starkville, Columbus, and the Mississippi side of the Memphis metro. 662 split off from 601 in 1999; 471 was added as an overlay in 2026.
Gulf Coast (228): Biloxi, Gulfport, Pascagoula, and the three coastal counties. Split off from 601 in 1997.
What’s Next for Mississippi Area Codes
Mississippi’s numbering pool gained substantial runway with the January 2026 activation of the 471 overlay in the north, which followed a 2023 NANPA projection that the 662 area would approach prefix exhaustion by early 2026. The 601/769 complex serving Jackson and central Mississippi remains the most heavily used and is the most likely candidate for any future relief, but no Mississippi numbering plan area appears on NANPA’s near-term relief schedule. The 228 Gulf Coast area is small enough that exhaustion is not expected for the foreseeable future.
Frequently Asked Questions
How many area codes does Mississippi have right now?
Mississippi has 5 active area codes in service across the territory it covers, including any overlays that share geography with an older code.
What is the oldest area code in Mississippi?
601 is the oldest active area code in Mississippi, assigned in 1947 when the North American Numbering Plan launched. It remains in service today, though its geographic footprint has typically been reduced by subsequent splits and overlays.
What is the newest area code in Mississippi?
The most recent area code addition to Mississippi was 471, activated in 2026. New phone lines provisioned in its service area are increasingly drawn from this code as older overlays approach exhaustion.
Why does Mississippi need so many area codes?
Population growth combined with the proliferation of mobile lines, business direct-dial numbers, VoIP services, and connected devices has exhausted older codes faster than the original 1947 plan anticipated. Each new area code adds roughly 7.9 million additional phone numbers to the regional pool.
How many area codes does Mississippi have?
Mississippi has 5 active area codes as of 2026: 228 on the Gulf Coast, 601 and 769 in central and southern Mississippi, and 662 and 471 in the northern half of the state. The newest, 471, went into service on January 30, 2026 as an overlay of 662.
What area code covers Jackson, Mississippi?
Jackson and central Mississippi are served by 601, the state’s original 1947 area code, along with its overlay 769, which was added in 2005. Both cover the same territory, so new lines in the Jackson area may be assigned either code and ten-digit dialing is required.
Is 471 a real Mississippi area code?
Yes. 471 is the newest Mississippi area code, placed in service on January 30, 2026 as an overlay of 662 across the northern half of the state. It shares the same region as 662, covering cities such as Tupelo, Oxford, Southaven, and Starkville.
What area code is the Mississippi Gulf Coast?
The Gulf Coast uses 228, which split off from 601 in 1997. It covers Hancock, Harrison, and Jackson counties, including Biloxi, Gulfport, Pascagoula, and Bay St. Louis. It is the only area code serving the coast and is not expected to need an overlay soon.
