Area Code 571: Where Is It Located? A Comprehensive Guide

Are you wondering about area code 571? This comprehensive guide will clarify its location and provide valuable information for anyone needing to understand this important piece of telecommunications data.

Understanding Area Code 571

Area code 571 is an overlay area code serving Northern Virginia, specifically the greater Washington, D.C. metropolitan area. This means it wasn't created to replace an existing area code, but rather to supplement the existing codes, adding capacity to handle the region's growing number of telephone lines.

What does "overlay" mean?

An overlay plan introduces a new area code to an area already served by one or more existing area codes. This is different from a geographic split, where an area is divided, with different areas receiving new area codes. In an overlay, both the original and the new area codes serve the same geographic region. This means you might encounter multiple area codes in the same city or even on the same street!

Area code 571 covers a large swathe of Northern Virginia, encompassing numerous cities and towns. Some of the key areas served include:

It's crucial to note that the boundaries aren't always perfectly defined, and some areas might transition between area codes. Always confirm the precise area code before making a call to avoid miscommunication.
