If you’re typing zip code for McLean VA into a search bar, you’re probably looking for one of two things: a quick five-digit number for a shipping label, or the "secret code" to understanding one of the wealthiest enclaves in the United States.
It’s a bit of a maze. Honestly, if you just use "22101" for everything, you're going to run into trouble eventually. McLean isn't just one big block; it’s a patchwork of high-stakes business districts, quiet riverfront estates, and suburban pockets that technically overlap with other towns.

The Big Two: 22101 vs. 22102
Most of the time, when people talk about McLean, they mean 22101. This is the classic, "old money" side of town. It’s where you find the sprawling estates along the Potomac River and the historic Langley area. If you’re heading to the CIA headquarters or looking for the massive homes tucked away behind heavy gates on Chain Bridge Road, you’re in 22101.
Then there’s 22102. As extensively documented in latest reports by The Spruce, the results are worth noting.
This zip code is the high-energy sibling. It covers the northern part of McLean and a massive chunk of Tysons. If you’re going to the Tysons Corner Center to shop or heading to a high-rise office building on Jones Branch Drive, you’re firmly in 22102 territory. It’s more urban, more vertical, and a lot more "hustle and bustle" than the 22101 side of the tracks.
The Ones Everyone Forgets
- 22103: This is strictly for P.O. Boxes. You won't find a house with this address.
- 22106: Another one reserved for the post office, specifically for those with boxes at the McLean branch.
- 22107, 22108, 22109: These are specialized codes often used for large organizations or high-volume mailers. Basically, unless you work for a government agency or a massive corporation, you’ll never need to write these down.
Why the Zip Code Actually Matters in 2026
You’d think in 2026, with GPS and drones, a zip code would be a relic. It's not.
In Northern Virginia, your zip code is a status symbol, a school boundary marker, and a real estate predictor all rolled into one. For instance, the median sale price in 22101 recently hovered around $1,987,500 as of early 2026. Buyers here are looking for privacy and "legacy" homes.
Contrast that with 22102, where the vibe is different. You have more luxury condos and townhomes. The population is younger—median age is around 38 compared to 46 in 22101—and people are there for the proximity to the Silver Line Metro and the "walkable" (well, sort of) urban lifestyle of Tysons.
Real Estate Realities
The market is shifting. We're seeing a "normalization" across the DC metro area right now. According to the Northern Virginia Association of Realtors (NVAR), inventory is actually rising—up nearly 36% in some spots—which means buyers finally have a bit of breathing room.
But McLean is still McLean.
A house on Georgetown Pike (22101) recently sold for $13.5 million, significantly over the list price. Meanwhile, some of the newer builds in 22102 are sitting a bit longer as buyers get picky about "value alignment." It’s a weird time. People aren't just panic-buying anymore. They want the right zip code, but they want it to make sense on a spreadsheet.
The Tysons Identity Crisis
Is Tysons in McLean? Is it its own city? It’s complicated.
Technically, Tysons used to be "Tysons Corner," a sleepy crossroads. Now, it's a massive "edge city." If you live in a luxury apartment building right next to the Boro or the Galleria, your mailing address will often say McLean, VA 22102.
However, some parts of that same commercial hub might use a Vienna address depending on which side of the road they sit. This "border war" between zip codes causes endless confusion for delivery drivers and newcomers.
Pro Tip: If you're moving to the area, always check the specific tax district. Even if your address says "McLean," your taxes (and your kids' schools) are dictated by the county boundaries and specific zip designations.
Schools: The 22101/22102 Divide
For many families, the search for a zip code for McLean VA is actually a search for a school district.
Fairfax County Public Schools (FCPS) are top-tier, but the boundaries are strict. Generally:
- 22101 usually feeds into Langley High School or McLean High School. These are two of the most competitive schools in the state.
- 22102 can be a bit more of a mix. Depending on exactly where the line falls, you might be looking at Marshall High School, which has a fantastic IB program, or McLean High.
It’s not just about the high schools, either. Elementary schools like Chesterbrook (22101) and Spring Hill (22102) are huge draws for the area. People will literally pay a $200,000 premium just to be on the "right" side of a street that divides two elementary school zones. It sounds crazy to outsiders, but here, it’s just Tuesday.
Navigating the "McLean-Adjacent" Zones
Sometimes you’ll see a house listed as being in McLean, but the zip code is 22043 (Falls Church) or 22066 (Great Falls).
Real estate agents love to stretch the "McLean" brand because it adds instant value. But honestly? If the zip code starts with 220, you’re technically in a different town, even if you’re five minutes from the McLean downtown core. Great Falls (22066) is even more rural and estate-heavy, while Falls Church (22043) tends to have more mid-century modern homes and slightly smaller lots.
Actionable Steps for Your Search
If you're trying to nail down the right spot in McLean, don't just look at the houses. Look at the maps.
- Check the Flood and Heat Factors: Surprisingly, about 15% of properties in 22101 are at risk of severe flooding over the next few decades. Before you fall in love with a riverfront property, check the First Street risk data.
- Verify the School Map: Use the FCPS "Boundary Locator" tool. Never trust a real estate listing that just says "McLean Schools." Type in the specific address to see which elementary, middle, and high school it actually serves.
- Commute Test: If you're looking at 22102, drive from the property to the 495 on-ramp at 8:30 AM. Tysons traffic is a different beast entirely.
- Confirm the Mailing Address: If you’re a business owner, a 22101 address still carries a certain "weight" in the DC power circles that 22102 doesn't quite match yet, despite the latter's shiny new glass towers.
McLean is a beautiful, expensive, and sometimes confusing place. Whether you're here for the power of 22101 or the convenience of 22102, knowing your zip code is the first step to actually fitting in.
