Which Ohio Area Code Covers Where

5 of Ohio's area codes share territory with another. Codes in the same row serve the same places, so either can reach a number there — and ten-digit dialling is required throughout.

How Ohio Got Its Area Codes

Ohio went from 4 area codes in 1947 to 15 today. A split carves territory off its parent; an overlay sits on top of it, which is why newer codes need ten-digit dialling.
