Find any 571- phone number in Virginia
The 571 area code is an area code in northern Virginia, and is one of the area codes in the North American Numbering Plan. It was created in 2000, when area code 703, which had previously served all of northern Virginia, was split due to the rapid growth of the region. Area code 571 covers Fairfax County and parts of Manassas, Reston, and Loudon.
The North American Numbering Plan is an area code system used by the United States and parts of Canada, made up of 3-digit area codes and 3- or 4-digit prefixes. Each area code is assigned to a specific geographic region, and is used to assign phone numbers to that area. Area codes also make it easier to identify an incoming call, since they are usually used by local telephone companies to assign phone numbers. This system is continually monitored by The North American Numbering Plan Administrator, and new area codes are added as needed for population growth.
