This is a list of telephone area codes in the state of Oregon.
As of 2022, it is one of six states (along with Pennsylvania, Connecticut, Maryland, Idaho and West Virginia) that is entirely overlaid.
503: The northwestern corner of Oregon, including Portland and its metropolitan area, Salem and other cities 541: All of Oregon outside the northwestern corner, including Eugene 971: An overlay of area code 503.
Until 2008, 971 was a concentrated overlay, meaning it was only present in some parts of the 503 area.
Under the original North American Numbering Plan of 1947, area code 503 covered all of Oregon.
