Area code 451 vs 828
451 and 828 are overlay codes: they cover the same ground in North Carolina, and a number in one is a local call to the other. Today 451 has 0 of 786 blocks assigned (0.0%) and 828 has 724 of 786 (92.1%), so a new number in the area now almost always comes from 451. 828 appears in the complaint data with 570 complaints in the window; 451 does not appear at all, which is what you would expect of a code that is not yet in service. 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.
