The other area codes laid over 571
Area code 571 does not have Arlington, Virginia to itself. 1 other code — 703 — serves the same rate centres, laid over the same ground rather than dividing it. That is an overlay: a new code added when the old one ran out of numbers, covering the same streets. Two neighbours can hold different area codes, so the code says roughly when a number was issued rather than where it sits.
7034,509 blocks, 19 rate centres, mostly landline
Each holds its own blocks and its own carrier mix, so a 571 number and a 703 number from the same street can report different line types. Filtering Arlington, Virginia by area code needs all 2 of them.

Common questions
Where is area code 571?
Area code 571 covers Arlington, Virginia. It is not the only code there: 703 is an overlay on the same rate centres, so a Arlington, Virginia number can start with any of them.
Is a 571 number a mobile or a landline?
It can be either, and the digits do not say which. North American mobile and landline numbers share the same ranges, so the answer comes from the carrier holding the block. In 571 the split runs 47% mobile, 36% landline and 18% VoIP, so mobile is the most likely single answer.
Which carriers hold 571 numbers?
The largest holders are AT&T Wireless, Onvoy, Verizon Wireless. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 571 numbers are there?
The code holds 6,574 allocated blocks in our copy of the numbering plan. A block is 1,000 or 10,000 consecutive numbers depending on how deeply it has been pooled, so 571 covers on the order of 6,574,000 possible numbers — most of which have never been issued to anyone.
