History of the 503 Area Code

503 area code is one of the original 86 area codes, introduced back in 1947. After a couple of decades, 503 phone numbers were on the verge of being overused, which led to its split, establishing the 541 area code. Since then, 503 has been serving Portland and its neighboring suburbs, while 541 is handling the demand of Oregon’s other half.

The North America Numbering Plan Administration (NANPA) noticed the need for a new area code as the region's necessity continued growing. So, in 2000, area code 917 was added as an overlay to the existing 503, making the service more accessible and prominent.

They are economical, to start. Calilio offers plans that are more reasonable than those of other providers, and they offer a wide range of services.
