About 503 Area Code
Area code 503 serves Portland and northwestern Oregon. Introduced in 1947 as one of the original North American area codes, 503 initially covered the entire state until a 1995 split created area code 541. Today, 503 covers the Portland metro area including Salem, Gresham, Hillsboro, Beaverton and Tigard across ten counties. The code supports local voice and SMS-capable numbers used by businesses, tech companies, healthcare providers and educational institutions throughout Oregon's most populous region.
The 503 region anchors Oregon's economy with its "Silicon Forest" tech corridor where Intel employs over 20,000 workers and hundreds of footwear and sportswear companies including Nike, Adidas, Columbia Sportswear and Under Armour maintain headquarters or major design centers. Portland's progressive culture, craft brewing scene and sustainability focus attract creative talent and startups. Local businesses use 503 numbers for customer support, appointment reminders, sales calls and field coordination. Regional numbers deliver higher answer rates than toll-free alternatives because they signal authentic presence in one of the West Coast's most dynamic urban markets.
