971 overlay codes and dialing
The 971 territory is covered by an overlay of 2 area codes: 503, 971. All of them serve the same geographic area, and the original code is 503. Because more than one code covers the same ground, 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.
History of the 971 area code
971 went into service on October 1, 2000 as an overlay of 503, relieving number exhaustion in the Portland area. Rather than splitting the region, the overlay lets 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 in Portland, OR or trustworthy. See spam & scam-risk area codes for how spoofing works and how to respond.
