Questions about this area code
Where is area code 571?
571 is a Virginia area code covering Northern Virginia, near Washington. NANPA's report lists 645 exchanges in use across 19 rate centres.
Is 571 a mobile or a landline area code?
Both. An area code doesn't decide the line type: mobile, landline and VoIP numbers all use 571, and numbers move between carriers. Check the number itself to see what it is today.
Which area codes overlay 571?
703 has numbers in at least half of the same places as 571, so a new number there can get any of these area codes.
Can you tell me who owns a 571 number?
No. NumberLookup shows whether a number is valid, its line type, its carrier and its region, never the person or business behind it.
Source: NANPA's public central office code and thousands-block reports, refreshed weekly. Carriers are the ones the numbers were assigned to, not necessarily today's, and never the person who uses a number.
