History of Area Code 503
Area code 503 was established in 1947 as one of the original area codes in the North American Numbering Plan. It originally covered the entire state of Oregon. On November 5, 1995, area code 541 split from 503 and took most of Oregon outside the northwest, while 503 remained in Portland, Salem, and nearby communities.
Area code 971 was later added as an overlay to the 503 region. The overlay supplied additional telephone numbers in the same geographic area instead of moving existing communities to a new area code.
