Overlay System

Area codes 503 and 971 work together as an overlay system in the same geographic region of northwestern Oregon. Area code 503 was one of the original North American area codes of 1947. Area code 971 was created as a concentrated overlay for most of the numbering plan area on July 1, 1999, with the previously exempted Clatsop and Tillamook counties added to the overlay on April 27, 2008. Ten-digit dialing became mandatory across northwest Oregon on October 1, 2000.

971 Area Code Prefixes

Our Oregon phone number lookup service will analyze the three-digit prefix of any 971 area code phone number and will show which telecommunications company and rate center it was initially assigned to. This prefix code data may help to determine the U.S. carrier, Oregon geographic region, and local calling area associated with the phone number.

Phone numbers follow the following structure under the North American Numbering Plan:

  • NPA- area code (where the number was originally assigned)
  • NXX - Central office code that locates the specific neighborhood and identifies the service provider
  • XXXX - Subscriber number identifies the individual phone line within that local exchange

Understanding the area code can help you determine if a call is local to your area. However, keep in mind that due to mobile number portability and VoIP services, the caller may be anywhere in the United States, so it’s best to search for the most recent phone number details.
