The 971 area code serves northwestern Oregon, anchored by Portland and stretching south to Salem, the state capital, and west toward the coastal city of Astoria. It also reaches Gresham, Hillsboro (the hub of Oregon's Silicon Forest tech cluster) and Beaverton, spanning roughly ten counties including Multnomah, Washington, Marion, Polk and Yamhill, home to Willamette Valley wine country, together totaling about 64 cities and more than 2.6 million residents. The region sits in the Pacific Time Zone, observing PST at UTC-8 and PDT at UTC-7. Area code 503 was one of the original 1947 area codes covering all of Oregon; as the state split repeatedly through the mid-1990s, 503 was eventually narrowed to the northwest corner, and even that supply ran short as mobile phones and fax lines multiplied. Rather than split the territory again, regulators layered 971 directly on top of 503 starting October 1, 2000, with the overlay completed in stages by 2008, which is why all local calls in the region now require ten-digit dialing. Because the two codes cover identical geography, a 971 number carries the same local credibility as a 503 number. As with any area code, scammers sometimes spoof 971 numbers to look like a trusted Oregon neighbor, so the article recommends letting unknown calls go to voicemail, never sharing financial details with unsolicited callers, and verifying any bank or agency claim by calling the number on your official statement, while noting that STIR/SHAKEN call authentication helps legitimate business calls avoid being flagged as spam. The post also positions a 971 number as an easy way for outside businesses to establish Oregon credibility without opening a physical office there, since cloud and VoIP providers can provision a local number and route it anywhere.
