If you’ve ever wondered about phone numbers beginning with 571, you’re discovering a gateway to one of America’s most prosperous regions. This three-digit prefix connects you to Northern Virginia, a bustling area that sits shoulder-to-shoulder with our nation’s capital.
Breaking Down the 571 Phone Code
Think of 571 as Northern Virginia’s digital address. Unlike traditional area codes that get their own territory, 571 shares its space with the original 703 code. This unique arrangement, called an overlay system, means both prefixes serve identical locations throughout the region.

How 571 Came to Exist
The Phone Number Crisis of 2000
Virginia’s telephone story started simply in 1947 with a single code – 703 – covering the entire Commonwealth. But as decades rolled by, the explosive growth around Washington, D.C. forced multiple divisions.
Evolution timeline:
- 1947: Single 703 designation for entire state
- 1973: Richmond area separated into 804
- 1995: Western regions assigned 540
- 2000: 571 layered over 703 in Northern Virginia
By the late 1990s, Northern Virginia faced a telecommunications emergency. The digital revolution brought:
- Explosive population increases
- Cell phone adoption going mainstream
- Business fax lines multiplying
- Home offices requiring dedicated lines
- Pager services expanding
Simply put, 703 had no more numbers left to assign.
Rather than redrawing boundaries and forcing established businesses, federal offices, and residents to change their longstanding phone numbers, telecommunications authorities chose the overlay solution. They superimposed 571 on top of 703, instantly creating millions of fresh number combinations.
Critical detail: This overlay implementation mandated that everyone dial all ten digits (code plus number) for every call, including across-the-street neighbors.

Frequently Asked Questions
Do 571 and 703 work differently?
Functionally, they’re identical. Both codes serve the same Northern Virginia geography. The 571 addition in 2000 solved a number shortage – they operate as twin systems covering identical territory.
Can I select which code I get?
When requesting new service, you’ll receive whatever numbers your provider has available. You can express a preference, though availability ultimately determines your assignment.
Does 571 mean my number is recent?
Usually. Since 571 launched in 2000, these numbers generally indicate newer service compared to 703. But both prefixes work identically regardless of age.
Will my area code impact service performance?
Absolutely not. Your code (571 or 703) serves purely as an identifier. Call quality, features, and reliability remain consistent across both.
Could another code get added later?
Potentially. If growth exhausts both 571 and 703 capacity, authorities might introduce an additional overlay. Current supply appears adequate for the foreseeable future.
