Shares the area
From the public records of the body that runs US phone numbering, read October 21, 2026.
503 was Oregon's only area code from 1947. In 1995 the south and east of the state were split off as 541, and the northwest kept 503.
A second code, 971, entered service over the same area on October 1, 2000, and since April 27, 2008 it has covered the north coast too. Every local call is dialed with all ten digits.
