History of Area Code 503

Area code 503 was one of Oregon's original area codes established by the Bell System in 1947. Initially, the code provided service for the entire state but underwent several changes. In 1995, area code 541 was established to serve all areas outside the Portland and Salem metropolitan areas, reducing the 503 regions.

Shortly after that, in 2000, a new area code, 971, was introduced as an overlay for the existing area within the 503 zone. Ten-digit dialing was implemented, requiring callers to dial the area code even when making local calls. Today, the two area codes coexist and function together.

Area code 503 serves Oregon's diverse, dynamic, and economically thriving region. With cities like Portland and Salem within its boundaries, the area reaches from the high-tech corridors to the brewery scene. Spanning over 300 zip codes, millions of residents, and a wide array of industries, area code 503 is a vital part of the United States telecommunication infrastructure.
