It is part of the 571/703 overlay complex — these codes share the same territory. Note that porting and VoIP mean a 703 number can be used from anywhere — the code marks where the number was assigned.

FAQ
Why do 571 and 703 cover the same place?
They are overlays: when a code runs low on numbers, a new code is added over the same territory instead of splitting it. The 571/703 complex shares one service area, and local calls are dialed with 10 digits.
Will 703 run out of numbers?
NANPA's current forecast projects exhaust in 1Q 2031, so a new overlay is likely to be planned.
Why am I getting spam calls from 703 numbers?
Scammers spoof recognizable area codes so calls look local or familiar. A displayed 703 number does not prove the call originated there — see our guide to spotting spoofed calls.
Where is a 703 number from?
703 is assigned to Washington and surrounding areas of Virginia in the Eastern time zone. The three digits after the area code (the prefix) narrow it down to a rate center.
Is 703 a toll-free number?
No. 703 is a geographic code; calls are billed like any other domestic call. Toll-free codes are 800, 833, 844, 855, 866, 877 and 888.
