8 area codes assigned to Wisconsin · Central Time
1 of Wisconsin'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.
The remaining 6 codes cover their own area: 262, 274, 353, 414, 608, 920.
Wisconsin went from 2 area codes in 1947 to 8 today. A split carves territory off its parent; an overlay sits on top of it, which is why newer codes need ten-digit dialling.
