About area code 503
Area code 503 is one of the North American Numbering Plan (NANP) codes serving Oregon. In the NANP a full number looks like +1 (503) NXX-XXXX: the +1 is the country code for the US and Canada, 503 is the area code, and the remaining seven digits identify the specific line. A call is charged by your own carrier's plan, not by the area code itself.
