McLean, VA utilizes an area code overlay in which area codes 703 and 571 serve the same geographic area. Ten digit dialing (area code + seven digit number) is necessary because two different homes in the same geographic area can have the same seven digit phone number but each would have a different area code. The area code overlay today was put into service in 2000 when area code 703 was overlaid with area code 571. Area code 703 was the original area codes assigned to cover all of Virginia in 1947.
In addition to McLean, VA area codes 703 and 571 serve northeastern Virginia which includes many suburbs of Washington, D.C. including the larger cities and communities of Alexandria, Annandale, Arlington, Burke, Centreville, Chantilly, Dale City, Fairfax, Franconia, Groveton, Herndon, Lake Ridge, Leesburg, Manassas, Mclean, Mount Vernon, Oakton, Reston, Springfield, West Springfield, and Woodbridge in addition to many smaller communities within the service area.
