The area code 703 is located in Alexandria, Virginia.
Area code 703 serves Alexandria, Virginia, and much of Northern Virginia, right across the Potomac River from Washington, D.C. It is one of Virginia’s most historic calling areas and includes major government, business, and tech hubs that support the nation’s capital. First assigned in 1947, 703 originally covered all of Virginia before later splits created 804 (1973) and 540 (1995); today it focuses on the D.C. suburbs in Virginia. An overlay, area code 571, was added in 2000, so ten-digit dialing is required for local calls.
