What is what area code is 971?

Area code 971 overlays a large portion of Oregon. It's not geographically limited to a single city or region, but rather serves a broad swath of the state, including areas around Portland and many other cities and towns throughout western Oregon. It's important to note that it's an overlay code, meaning it was added to an existing area code (primarily 503) to handle increasing demand for phone numbers. Therefore, you'll find both 503 and 971 numbers in use in the same general geographic area.
