History of the 503 Area Code
The 503 area code was one of the original 86 area codes introduced in 1947 under the North American Numbering Plan. At first, it covered the entire state of Oregon. As the population grew and phone usage increased over the decades, the 503 numbers began running out. To solve this, the state was split in 1995, creating the new 541 area code. After the split, 503 continued serving Portland, Salem, and nearby northwestern cities, while 541 covered the rest of Oregon.
To handle the ongoing demand for new phone numbers in the region, the North American Numbering Plan Administration approved an overlay. In 1999, the 971 area code was added as an overlay to 503. This change introduced mandatory 10-digit dialing for local calls. Since then, 503 and 971 have jointly served Portland and its surrounding areas, continuing to represent Oregon’s most populated and economically active region.
