History of the 571 Area Code
The 571 area code was introduced in 2000 as an overlay to the existing 703 area code. The primary reason for this addition was the rapid growth in the region, which led to an increased demand for new telephone numbers. Overlays are a common solution to address the exhaustion of available numbers in a given area without requiring existing customers to change their phone numbers.
