History of Area Code 571
Area code 571 entered service on March 1, 2000, as an overlay of area code 703. An overlay adds a new area code to an existing geographic service area, so 571 was not created by dividing Northern Virginia into separate regions.
Area code 703 was one of the original area codes assigned in 1947, when it covered the entire state of Virginia. Later area code splits reduced 703 to Northern Virginia. The 571 overlay added telephone number capacity as the region grew and allowed existing 703 customers to keep their numbers.
