The primary postal designation for Ashburn, Virginia, is 20140, serving as the historic and commercial core of this booming Loudoun County community. If you're looking for precise boundaries, median home prices, or practical local details, you've come to the right place.
Located roughly 30 miles west of Washington, D.C., the Ashburn zip code covers a diverse suburban territory that stretches from major commuter arteries toward older residential pockets.
