History of Area Code 571

Area code 571 began service on March 1, 2000. The North American Numbering Plan added it as an overlay for the existing 703 area code in northern Virginia. An overlay means both area codes serve the same geographic area.

Area code 703 had served the region since 1947, when it covered the entire state of Virginia. As telephone demand grew, Virginia split 703 several times before 571 was added. Area code 540 split from 703 in 1995, and continued growth in Northern Virginia led to the 571 overlay five years later.
