That was my zip code!
How does 463 fit in then? That one is pretty recent.
Sigh. I suppose we’ve fully run out of possible new area codes with 1 or 0 as their second digit? OK, 463 is fine then. Better than 460, that’s for sure.
I lived in Chicago during the 312 / 708 split, and in L.A. for 213 / 818. Landed on the wrong side of both, but at least 708 and 818 followed the Old Ways and are, on their face, Legit Area Codes. Luckily by the time 310 came along, I’d left town.
