Mississippi area codes
The table below lists every active Mississippi area code with its coverage, service date and prefix count. 4 of the 5 codes are overlays — added on top of existing territories as numbers ran short.
Geographically the map reads: 601 (Jackson), 662 (Tupelo), 228 (Biloxi), 769 (Jackson). Each code page lists its full coverage down to individual rate centers.
2 overlay complexes operate in Mississippi: 471/662, 601/769. Inside a complex the codes share territory and local calls take ten digits.
Since 2010 the state has gained 1 code: 471 (2026).
Every Mississippi code keeps Central time.
228 has served Biloxi since 1997, carries 271 active prefixes across 11 rate centers, split among 42 carriers. 195 of its prefixes are pooled — shared between carriers in thousands-number blocks. NANPA projects its capacity to last until 3Q 2105 — no relief needed for decades. It was created from 601. Local calls can still be dialed with seven digits — increasingly rare in the NANP.
471, in service since 2026, anchors Mississippi. It was created from 662. Local dialing is ten digits.
601, in service since 1947, anchors Jackson, carries 772 active prefixes across 106 rate centers, split among 35 carriers. 455 of its prefixes are pooled — shared between carriers in thousands-number blocks.

Note that toll-free codes (800, 833, 844, 855, 866, 877, 888) sit outside this list — they have no geographic tie to Mississippi or anywhere else, and are assigned individually from the national SMS/800 registry.
As everywhere in the NANP: these codes say where numbers were issued, not where callers are. Per-code pages break coverage down to rate centers and prefixes.
