Alexandria, Virginia, is in area code 571. This area code is an overlay for area code 703, meaning both codes serve the same geographic region in Northern Virginia. This overlay system maximizes available phone numbers in the area.

Northern Virginia utilizes two area codes, 703 and 571, to accommodate the region's growth and high demand for phone numbers. Area code 571 was implemented as an overlay to 703 in 2000, preventing the need for a disruptive geographic split.

Dialing a 571 number from a 703 number, or vice-versa, requires 10-digit dialing: the area code plus the seven-digit number. This applies even if calling within the same city or building due to the area code overlay.

Area code 571 is an overlay area code. This means it shares the same geographic area as another area code, which is 703 in Northern Virginia. Overlays are implemented to provide more phone numbers within a specific region rather than splitting it geographically.

Ten-digit dialing (area code + number) is mandatory for all calls within the 571 and 703 area codes, even for local calls. For long-distance calls outside this region, use 1 + 10 digits (1 + area code + number).

Area code 571 provides coverage for parts of Fauquier, Loudoun, and Prince William counties in Northern Virginia. It also covers Alexandria, Arlington, Fairfax, Falls Church, and Manassas, among other areas.
