The 503 area code is overlaid by area code 971. Both cover the same geographic region and are used interchangeably for new number assignments.
An overlay area code serves the same region as an existing area code and allows more phone numbers to be issued without changing anyone's current number.
There are over 300 active area codes in the United States, with more being added regularly to keep up with population growth and demand.
Originally, area codes were assigned based on geography and population size. Today, overlays and other methods are used to meet demand, making the system more flexible but less geographically precise.
