Quick answer: The 703 area code covers Northern Virginia — Arlington and Fairfax counties in full, parts of Loudoun, Prince William, and Fauquier, plus the independent cities of Alexandria, Fairfax, Falls Church, Manassas, and Manassas Park. It's one of the original 86 NANP codes from October 1947 and once covered all of Virginia before being trimmed by 804 (1973), 540 (1995), and 276 (2001). The 571 overlay has shared the same map since March 1, 2000, so 10-digit dialing is required for every local call — but there's no cost change.
703 area code: what it covers and how to get one
A caller ID showing 703 still carries weight. It signals Washington, D.C.'s doorstep — the government contractors, tech firms, and law offices of Northern Virginia. That's why businesses far outside Arlington still want a number that starts with those three digits.
This guide breaks down exactly where this code reaches, why every local call now needs 10 digits, and how to claim a Northern Virginia line without moving there.
We're My Country Mobile (MCM), and we set up local numbers in 190+ countries — so let's keep it practical.
Where is the 703 area code located?
The 703 area code serves Northern Virginia — the dense, fast-growing region hugging the western edge of Washington, D.C. It does not cover the rest of the state.
It sits entirely in the Eastern Time Zone (UTC−5, or UTC−4 during daylight saving). So a 9 a.m. call from Virginia matches D.C., New York, and Atlanta.
A quick history
This code is older than most. It was one of the original 86 North American area codes assigned in October 1947, and back then it covered all of Virginia. As the state's phone demand grew, the region kept shrinking until it settled over the Northern Virginia suburbs.
Cities and counties in the 703 region
Coverage spans roughly 36 cities and nine counties, with a combined population near 2.6 million. The independent cities of Alexandria, Fairfax, Falls Church, Manassas, and Manassas Park all fall inside it.
Here's a snapshot of the main areas this Northern Virginia code reaches.
| Area type | Examples |
|---|---|
| Independent cities | Alexandria, Fairfax, Falls Church, Manassas, Manassas Park |
| Major communities | Arlington, Reston, Centreville, Leesburg |
| Full counties | Arlington County, Fairfax County |
| Partial counties | Loudoun, Prince William, Fauquier |
Why businesses want this code
Northern Virginia runs on government contracting, defense, cloud computing, and professional services. A local virtual phone number tells clients and agencies you're close, reachable, and serious about the market.

The story behind 703: from a whole state to NoVa
When 703 launched in 1947, it covered every county in Virginia. As phone use exploded across the state, three splits carved it down to today's footprint:
- 1973 — 804 carved off eastern Virginia and Richmond.
- 1995 — 540 carved off western Virginia and Roanoke.
- 2001 — 276 carved off far southwest Virginia.
By the time the last split happened, 703 had settled over Northern Virginia — the dense suburbs closest to Washington, D.C. That's the footprint that exists today.
The 571 overlay: why you now dial 10 digits
Here's the part most guides skip. Since March 1, 2000, this region has shared an overlay code — 571 — covering the exact same geography.
An overlay means two codes serve one area. New lines get 571; older lines keep 703. They sit side by side.
What the overlay changes for you
Because two codes occupy the same ground, the seven-digit shortcut is gone. Every local call here requires the full 10 digits — area code plus the seven-digit number.
This applies even when you're calling a neighbor. Forget the area code and the call simply won't connect.
Does the overlay affect cost?
No. An overlay does not make local calls long-distance or more expensive. Calls within the region stay local — you just dial more digits.
How to dial a 703 number
The format depends on where you're calling from. The rules are simple once you see them laid out.
| Calling from | What to dial |
|---|---|
| Within Northern Virginia | 703 + 7-digit number (10 digits total) |
| Elsewhere in the US/Canada | 1 + 703 + 7-digit number |
| Outside North America | Exit code + 1 + 703 + 7-digit number |
International callers replace "exit code" with their own (00 from most of Europe, 011 from outside the US when applicable). The country code for the US is always 1.
Is a call from 703 a scam?
Not by default. Millions of legitimate people and businesses use this code every day. But spoofing — faking a caller ID — is common across every US area code, and Northern Virginia is no exception.
How to stay safe
Treat any unexpected call as unverified, regardless of the number shown. Don't share financial details or one-time codes with an inbound caller.
If a call claims to be from a bank or agency, hang up and dial the official number yourself. Spoofed numbers can mimic a trusted 703 line perfectly.
How to get a 703 virtual number
You don't need a Virginia address or office to own a Northern Virginia line. A virtual number works over the internet and rings wherever you are.
The setup is straightforward with MCM:
- Pick the code — search available 703 numbers in the MCM portal.
- Choose call routing — forward to a mobile, desk phone, or app.
- Activate — your number goes live, usually within minutes.
What you can do with it
Once it's live, the number behaves like any business line — but smarter. You get call forwarding, voicemail-to-email, an auto-attendant, and call recording included.
That means a one-person consultancy in Texas can answer Fairfax County clients on a local line, with a menu that sounds like a full team.
Claim your Northern Virginia presence
The takeaway is simple: the 703 area code is a credibility marker, the 571 overlay means every local call needs 10 digits, and you can own a line here from anywhere in the world.
If a local presence in the D.C. metro would help you win clients, the next step is picking a number and pointing it at your phone.

Frequently asked questions
What area is the 703 area code?
It covers Northern Virginia, including Arlington, Alexandria, Fairfax, Reston, Leesburg, and parts of Loudoun and Prince William counties. It sits just west of Washington, D.C.
What time zone uses the 703 area code?
Eastern Time (UTC−5, shifting to UTC−4 during daylight saving). It matches Washington, D.C., New York, and the rest of the US East Coast.
What is the 571 area code, and how does it relate to 703?
571 is an overlay introduced in 2000. It covers the identical Northern Virginia geography, so 703 and 571 numbers are neighbors. The overlay is the reason 10-digit dialing is required.
Why do I have to dial 10 digits for a local call?
Because two area codes (703 and 571) share the same region, the network needs the area code to route every call correctly — even local ones. Seven-digit dialing no longer works there.
Can I get a 703 number if I don't live in Virginia?
Yes. A virtual number from a provider like MCM gives you a Northern Virginia line that rings on your existing phone, no matter where you're based.
Is the 703 area code safe to answer?
The code itself is legitimate and widely used. Stay cautious with unexpected calls, though — scammers can spoof any number. Never share sensitive details with an unverified inbound caller.
How much does a virtual 703 number cost?
Pricing depends on the plan and features you choose. With MCM you can start without a contract and scale as your call volume grows — check current rates in the portal.
