Area code 471 vs 662
471 and 662 are overlay codes: they cover the same ground in Mississippi, and a number in one is a local call to the other. 662 is the original, in service since 1999. 471 was added in 2026 because the first was filling up – that is what an overlay is for. Today 471 has 0 of 786 blocks assigned (0.0%) and 662 has 756 of 786 (96.2%), so a new number in the area now almost always comes from 471. 662 appears in the complaint data with 415 complaints in the window; 471 does not appear at all, which is what you would expect of a code that is barely used so far. Neither code is better or safer than the other. They are the same geography, the same carriers and the same dialing rules; the difference is only how long each has existed and how full it is.
