If you’ve ever dialed a number in Northern Virginia and wondered why it looks different from what you’d expect, you’re not alone. The Arlington VA area code situation is actually pretty interesting — and a little confusing if you’re new to the region. Whether you’re moving to the area, setting up a business line, or just trying to figure out which digits to dial, this guide breaks it all down in plain English.
What Is the Arlington VA Area Code?
Arlington, Virginia uses area code 703. This is the primary area code covering Northern Virginia, including not just Arlington but also Alexandria, Fairfax County, and several surrounding communities.
There’s also a second area code — 571 — that was introduced as an overlay to 703 back in 2000. An overlay means both area codes serve the exact same geographic region. So if someone gives you a Northern Virginia number starting with 571, that’s perfectly normal and completely local.
Here’s a quick breakdown:
- 703 — The original area code for Northern Virginia, in use since 1947
- 571 — Introduced in 2000 as an overlay due to high demand for new numbers
- Both codes are used for landlines and cell phones in Arlington and surrounding areas
A Brief History of the 703 Area Code
Back in 1947, the North American Numbering Plan split up the country into area codes for the first time. Virginia originally had one area code — 703 — covering the entire state. Over the decades, as the population grew, the state was divided further.
By 1995, eastern Virginia got its own code (757), and 703 became focused specifically on Northern Virginia. Then, as the tech boom of the late 1990s hit the DC suburbs hard, phone number demand skyrocketed. That’s exactly why 571 was layered on top in 2000.
Today, Arlington is one of the densest and most connected counties in the country, so it makes sense that it needs two area codes to handle the volume.

How the Overlay System Works in Arlington
A lot of people get tripped up by the 703/571 overlay. Here’s the thing — when two area codes cover the same area, 10-digit dialing becomes mandatory. That means even if you’re calling your neighbor across the street, you still need to dial the full 10 digits.
What This Means for Local Calls
- You cannot just dial 7 digits for a local call in Arlington
- Always dial the full area code + 7-digit number
- This applies to landlines, cell phones, and VoIP services
What This Means for New Phone Numbers
If you’re getting a new number in Arlington — whether for personal or business use — you might be assigned either a 703 or a 571 number. Both are equally “local.” Don’t let anyone tell you one is better than the other.
Arlington VA Area Code for Businesses
Setting up a business in Arlington? Your area code actually matters more than you might think. Local customers tend to trust and recognize 703 numbers because it’s been around for decades. However, 571 is just as legitimate and widely recognized across the DC metro area.
Tips for Businesses Using Arlington Area Codes
- Choose based on availability — 703 numbers may be harder to get since the pool is older and more allocated
- Use a local number for credibility — Avoid toll-free-only setups if your customer base is Northern Virginia
- List your number consistently — For local SEO, make sure your 703 or 571 number appears the same across your website, Google Business Profile, and directories
- Consider a virtual number — Many VoIP providers let you pick a 703 or 571 number even if your office isn’t physically in Arlington
Pros and Cons of Having an Arlington Area Code
Like anything, there are upsides and downsides to operating with an Arlington number.
Pros
- Local recognition — People in the DC metro area immediately associate 703/571 with Northern Virginia
- Trust factor — Local numbers get higher answer rates than unfamiliar or toll-free numbers
- Strong professional image — Arlington’s reputation as a business and government hub adds weight to a local number
- Portability — You can keep a 703 or 571 number even if you move within the region
Cons
- 10-digit dialing required — Even local calls require the full number, which some people find inconvenient
- Area code confusion — New residents sometimes mistake 571 numbers as non-local
- Number scarcity — Getting a “clean” or memorable 703 number can be difficult
- Spam association — Like all area codes, some 703/571 numbers have been used for robocalls, which can lower answer rates in certain contexts
Common Mistakes People Make With the Arlington Area Code
Even long-time residents make a few recurring errors. Here are the most common ones to avoid.
1. Forgetting to dial 10 digits This is the number one mistake. If you’ve moved from a smaller town where 7-digit dialing worked fine, you’ll need to retrain yourself immediately. In Arlington, 10 digits is always required.
2. Assuming 571 is a long-distance number It’s not. Both 703 and 571 are local to the same region. Calling a 571 number from a 703 number is a local call — no extra charges apply.
3. Treating area codes as a strict location indicator With cell phones and VoIP services, someone with a 703 number might not actually be in Arlington at all. People keep their numbers when they move. Don’t assume location based on area code alone.
4. Inconsistent business listings If your business phone number appears differently across platforms (e.g., with and without dashes, or switching between 703 and 571 for different listings), it can hurt your local search rankings.
5. Ignoring area code when registering with directories Some business owners list their number without an area code in local directories. This is a mistake — always include the full 10-digit number for proper local SEO.
Best Practices for Using an Arlington VA Number
Whether you’re a resident, remote worker, or business owner, here’s how to make the most of your Arlington area code.
- Always write your number in full — Include 703 or 571 every single time, in every format (website, email signature, business cards)
- Verify your number is active and routed correctly — Especially important if you use VoIP or call forwarding
- Keep your number consistent across platforms — Google, Yelp, Facebook, your website — all should show the exact same number
- Register with local directories — Arlington Chamber of Commerce, local business listings, and Virginia-specific directories all benefit from a proper local number
- Educate your staff — If you run a business, make sure everyone on your team knows to dial 10 digits for every call, internal or external
