Area code splits normally follow a simple rule: the largest, most established city keeps the original number, while newer or smaller territory gets reassigned. Virginia’s 1973 split broke that convention entirely. Richmond, the state capital and considerably larger city, ended up with the brand-new code 804, while Northern Virginia, the smaller territory at the time, kept the original 703. The reason wasn’t population, it was cost: the phone company specifically wanted to spare Northern Virginia’s dense concentration of federal agencies the expense and disruption of renumbering.

Why Federal Agencies Got Special Treatment
703 covered the entirety of Virginia when it launched in 1947. By 1973, the state needed its first split, and normal telecom practice would have handed the smaller northern territory a new number while Richmond retained the original. C&P Telephone deliberately reversed that logic, recognising that changing phone numbers for the enormous concentration of federal offices and agencies clustered around Washington DC would create disproportionate administrative burden compared to Richmond’s comparatively simpler renumbering. A second split followed in 1995, sending western Virginia into 540 and narrowing 703 down to its current Northern Virginia footprint.
Intelligence and Defence Sitting Side by Side
Arlington hosts the Pentagon, the headquarters of the entire US Department of Defense, drawing thousands of workers daily into this exact territory. Just a short distance away, the CIA’s headquarters in Langley adds another layer of national security infrastructure to the same corridor, making this one of the most institutionally significant patches of real estate in the entire country, all sharing a single area code.
Where This Code Actually Reaches
703 spans a dense, historically significant stretch of Northern Virginia:
- Arlington, packing over 230,000 residents into one of the state’s most densely populated areas
- Alexandria, known for its preserved historic district along the Potomac
- Fairfax County, a sprawling suburban zone mixing tech firms and established neighbourhoods
- Falls Church, Herndon, and Leesburg
Arlington in particular carries outsized significance relative to its size, functioning as both a federal government hub and a genuine urban centre in its own right, distinct from the more suburban character found further out in Fairfax County.
A Food Scene Shaped by Global Influence
Northern Virginia’s dense concentration of international federal workers, diplomats, and immigrant communities has fed a genuinely diverse food scene, spanning trendy restaurants in Alexandria’s historic core to authentic international cuisine scattered throughout Fairfax County. That culinary variety reflects the broader demographic mix drawn here by decades of government and defence contracting employment.
Why 571 Joined as an Overlay in 2000
Continued federal expansion and the tech industry’s growth eventually pushed 703’s numbering pool toward exhaustion, and rather than splitting Northern Virginia’s tightly interconnected corridor a third time, regulators introduced 571 as an overlay in March 2000. Both codes now share identical territory, and mandatory ten-digit dialing has applied across the region ever since.
Does the Original Code Still Signal Something Locally?
Because 703 predates 571 by more than five decades and carries that unusual history of being deliberately preserved for federal continuity, it’s often perceived as more established or prestigious among longtime Northern Virginia residents and businesses, even though both codes function identically for every practical purpose today.
Frequently Asked Questions
Q1. Why did Richmond get a new area code instead of Northern Virginia during the 1973 split?
Normal practice would have given the smaller territory the new code, but Northern Virginia’s dense concentration of federal agencies made C&P Telephone reluctant to force those offices through a costly renumbering process, so they reversed the usual convention and gave Richmond the new code instead.
Q2. Does a 703 number mean the caller is likely connected to a government agency?
It’s a reasonable possibility given the sheer concentration of federal offices, defence contractors, and intelligence agencies within this territory, though 703 also covers substantial tech, retail, and general suburban business activity unrelated to government work.
Q3. Is a 703 number more prestigious than a 571 number for a Northern Virginia business?
There’s a genuine perception advantage tied to 703 being the original 1947 code with a distinctive preservation history, though both function identically for calls, texts, and business registration today.
Q4. Can a business outside Virginia get a 703 number to establish a Northern Virginia presence?
Yes, virtual number and VoIP providers commonly issue 703 or 571 numbers to businesses anywhere, letting them establish a DC-adjacent presence for government contracting, technology, or general business outreach without needing a physical Virginia office.
