The area code 503 is located in Beaver, Oregon.
Area code 503 serves Beaver, Oregon, a small community in Tillamook County on the North Oregon Coast. This coastal area sits near the Nestucca River and the forested Coast Range, tying Beaver to both outdoor recreation and larger hubs in northwest Oregon. The region uses the Pacific Time Zone, and phone numbers here may show either 503 or its overlay, 971.
Area code 503 covers much of northwestern Oregon, including major cities and coastal towns that many callers recognize:
Established in 1947 as Oregon’s original area code, 503 once covered the entire state before 541 split off in 1995. The overlay 971 was introduced in 2000 and later expanded to cover the full 503 region, so 10-digit dialing is standard for local calls. In Beaver and across the coast, both area codes work the same way for landlines and mobile phones, and new numbers may be assigned in either code.
