The state of Oregon has a new area code effective February 10, 2010. The new code is 458 and it will cover the same area served by area code 541 (larger cities served: Bend, Eugene, Medford, Springfield). As a result, all Oregon phone numbers will be dialed using 10 digits now, even for local calls.
See NANPA announcement.
We apologize for only announcing this new area code addition today.
