Position your business at the centre of America's defence and technology economy with a 571 virtual number — the Pentagon, Amazon HQ2, Tysons Corner's IT giants, and Loudoun County's internet backbone, all in Northern Virginia. Activate instantly.
Area code 571 is an overlay covering Northern Virginia — Arlington, Alexandria, Fairfax, Loudoun, Prince William, and Stafford counties — sharing geography with the original 703 area code. Northern Virginia is one of the most economically powerful regions in the US, driven by an extraordinary concentration of defence and intelligence industry. The Pentagon is in Arlington; Amazon's HQ2 is in National Landing; Tysons Corner is home to DXC Technology, SAIC, and Booz Allen Hamilton; and the Dulles Technology Corridor hosts Leidos, ManTech, and Northrop Grumman. Loudoun County alone is sometimes called the internet capital of the world due to its extraordinary density of data centres serving the global internet backbone.
From Virginia Beach to Newport News 571 covers the Mid-Atlantic region of Virginia.
The Pentagon in Arlington employs 23,000+ military and civilian staff and manages hundreds of billions in annual procurement. Defence contractors, cybersecurity firms, and government technology vendors must have a Northern Virginia presence — and a 571 or 703 number — to be taken seriously in the DoD market.
Amazon's HQ2 in National Landing (Arlington) employs 25,000+ in technology and corporate roles and has catalysed a broader tech cluster in Northern Virginia. Technology, real estate, and professional services firms need a local 571 number to engage Amazon's Northern Virginia operations.
Tysons Corner is home to SAIC, DXC Technology, and Booz Allen Hamilton — three of the largest IT and government services firms in the US. A local 571 number is the standard credential for any technology or consulting firm seeking to engage Northern Virginia's defence and intelligence technology cluster.
Loudoun County's data centre concentration carries more internet traffic than any other location on Earth. Network, power, and infrastructure services companies serving this extraordinary concentration of hyperscale facilities need a local Northern Virginia number to signal genuine market presence.
