Area codes and dialing in Oregon
Oregon's 4 area codes mix older geographic codes with newer overlays. The busiest metros — around Eugene, Portland — carry the most numbers and rely on overlays, which is why 10-digit dialing is required there. Quieter parts of the state may still use a single code. The original code in the Oregon list is 458 (Eugene).
Whenever a Oregon region runs low on numbers, a new overlay is added on top rather than splitting the map, so existing customers keep their numbers. See 10-digit dialing for what that means in practice, or the newest area codes for upcoming changes.
Cities with multiple area codes
These Oregon metros are served by an overlay of two or more codes, so 10-digit dialing applies: Eugene · Portland.
