4 area codes assigned to Oregon · Pacific Time
2 of Oregon'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.
Oregon went from one area code in 1947 to 4 today. A split carves territory off its parent; an overlay sits on top of it, which is why newer codes need ten-digit dialling.
