2 area codes assigned to Idaho · Mountain Time
1 of Idaho'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.
Idaho went from one area code in 1947 to 2 today. A split carves territory off its parent; an overlay sits on top of it, which is why newer codes need ten-digit dialling.
