History of the 703 Area Code

The 703 area code was one of the original area codes established in 1947. Initially, it covered the entire state of Virginia. However, due to the increasing demand for telephone numbers, the area code underwent several changes:

  • In 1973, area code 804 was created to serve the eastern and southern parts of Virginia, reducing the coverage of 703.
  • In 1995, area code 540 was introduced to serve the western and southwestern regions of Virginia.
  • In 2000, area code 571 was overlaid on 703 to accommodate the growing population and the subsequent demand for more phone numbers.

These changes were managed by the North American Numbering Plan Administrator (NANPA).
