Overlay codes serving Portland
Portland is served by an overlay of 2 area codes: 503, 971. Because more than one code covers the same area, 10-digit dialing is mandatory — you must dial the area code for every local call. New phone lines may be assigned any of these codes, so Portland numbers are no longer tied to a single prefix.
History of the 971 area code
971 was introduced as an overlay to relieve number exhaustion in the Portland area, adding capacity on top of 503 rather than splitting the region. Overlays let existing customers keep their numbers while new lines draw from the added code. Learn more in our overlay guide.
Is 971 a scam or spam risk?
971 is a legitimate geographic area code, not a premium or toll line, so a call from it costs you nothing extra. That said, scammers frequently spoof real local area codes to look familiar on caller ID. A genuine 971 number on your screen is no guarantee the caller is local or trustworthy.
