Area Code 240: The Silent Mystery That Has Locals Speaking Up — Urgent and Quiet In the ever-changing landscape of telephone area codes in Northern Virginia, one mysteriously low-profile yet deeply impactful code stands out: 240. While often overshadowed by larger regional codes like 703 or 757, Area Code 240 carries a quiet but growing significance—sparking curiosity, revealing hidden stories, and reflecting a unique blend of urgency and calm in Fairfax County and surrounding communities. ### What Is Area Code 240? Originally assigned to Fairfax County in 1996, Area Code 240 was created as a split from 703 to better manage the surging demand for phone numbers in one of the fastest-growing tech and business hubs in the Washington, D.C. metro area. Today, it covers not only Fairfax County but also parts of northern Loudoun and Prince William counties, serving a diverse population of professionals, federal contractors, and families drawn to the region’s innovation and convenience.
