Area code 971 is an overlay for 503, covering northwestern Oregon, including Portland, Salem, and surrounding suburbs. Introduced in 2000, it was initially restricted to certain types of numbers before expanding in 2008 to cover all new lines. The region is a center of Pacific Northwest culture, with strong ties to technology, craft industries, and environmental advocacy. Ten-digit dialing is required. Area code 971 plays a supporting role in Oregon’s urban telecommunications infrastructure while still reflecting the progressive and artistic identity of the Portland metro area.
