About Area Code 571
Area code 571 is a North American Numbering Plan (NANP) area code that has been in service since 2000. It is administered by NANPA on behalf of the FCC and serves the Virginia region anchored on Arlington.
571 is an overlay code, which means it shares its geographic boundaries with one or more existing area codes (703). Overlays are created when a region exhausts the supply of phone numbers in its original area code. Within an overlay region, residents must dial all 10 digits even for local calls, because the same 7-digit number can exist under multiple area codes.
Mobile numbers in 571 are portable: a person who moved away from Arlington may still carry a 571 mobile number on their device. If you receive an unexpected call from a 571 number, run it through the reverse lookup tool above for the most accurate, free identification.
If you live or do business in Virginia, you may also interact with neighbouring or overlay codes (703). See the related codes section below to explore the rest of Virginia.
