Area codes 541 and 458

  Area codes 541 and 458

North American area code 541 covers the majority of Oregon in terms of surface area, except the northwest part of the state. Its service area includes the cities of Eugene, Springfield, Corvallis, Albany, Medford, Bend, Ashland, The Dalles, and Pendleton, as well as the coastal region from Lincoln County to the California border. It began its split from area code 503 on November 5, 1995, and finished June 30, 1996. It is overlaid with area code 458, effective February 10, 2010.

History

Area code 503 was used for the entire state of Oregon until November 5, 1995, when area code 541 began service. On that date, 503 was cut back to the heavily populated northwest corner of the state–including Portland and Salem–while the rest of the state moved to 541.[1] This was intended as a long-term solution. However, by 2007, 541 was on the brink of exhaustion due to the proliferation of cell phones and pagers, particularly in Eugene, Corvallis and Medford. As a solution, the Oregon Public Utility Commission approved a number overlay with area code 458 for the entire area,[2] resulting in mandatory 10-digit dialing for that area.[3] Oregon's other area code overlay (503/971) already had this requirement. Ten-digit dialing was phased in beginning in July 2009, becoming mandatory in January 2010.[4] The first exchange to be issued in the 458 area code was 205 in Eugene in August 2011.
