Area code 334 vs 483
334 and 483 are overlay codes: they cover the same ground in Alabama, and a number in one is a local call to the other. 334 is the original, in service since 1995. 483 was added in 2026 because the first was filling up – that is what an overlay is for. Today 334 has 784 of 786 blocks assigned (99.7%) and 483 has 14 of 786 (1.8%), so a new number in the area now almost always comes from 483. 334 appears in the complaint data with 525 complaints in the window; 483 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.
