The 458 area code covers a vast majority of Oregon, excluding the northwestern corner of the state where the Portland metropolitan area (area codes 503 and 971) is located. The 458 area code also encompasses the coastal region from Lincoln County down to the California border.

History of the 458 Area Code

Area code 541 was originally established in 1995 as a split from the 503 area code. However, by 2007, the 541 area code was nearing exhaustion due to the proliferation of cell phones and other devices. To address this, the Oregon Public Utility Commission approved an overlay plan, adding area code 458 to the same geographical region as 541 in 2010. This overlay means that both 458 and 541 area codes serve the same region, requiring residents to dial 10 digits (area code + phone number) for all calls, even local ones.

An overlay is a numbering plan where two or more area codes serve the same geographic region. In the case of 458 and 541, this means that:

  • New phone numbers can be assigned with either area code.
  • You must dial the area code for all calls, even if the other party has the same area code as you.
  • The overlay doesn’t affect rates or billing.
  • It doesn’t require you to change your existing phone number.
