Zip code 20120 covers the northern half of Centreville in western Fairfax County. It's one of the area's most established suburban markets, known for well-kept planned communities, mature trees, and easy access to the Route 28 and Dulles corridors.

Much of 20120 is made up of larger planned communities with their own pools, trails, and common areas. Sully Station and Virginia Run are two of the best known, and London Towne offers older townhomes from the 1960s. Expect a mix of colonials and split-levels from the 1970s through the 2000s, along with townhome communities that give buyers a lower-cost way into the area. Recent listings in 20120 have included homes in Sully Station, Newgate, London Towne and Faircrest.
I-66 and Route 29 run along the southern edge, Route 28 connects north to Dulles Airport and the tech corridor, and the Fairfax County Parkway is close by. Commuter buses and park-and-ride lots serve the I-66 corridor, and the Express Lanes give drivers a toll option at peak times.
Everyday shopping is close at hand along Route 29 and Union Mill Road, and the larger Fair Lakes and Fair Oaks retail areas are a short drive east. For the outdoors, the Cub Run stream valley trails run through the area, and Bull Run Regional Park and the Udvar-Hazy Center are both nearby.
Centreville grew quickly in the 1980s and 1990s as the Route 28 and Dulles corridors filled with jobs, and the planned communities of 20120 date mostly from that wave. The result is a neighborhood-by-neighborhood feel, with swim teams, community pools, and HOA events at the center of local life. Wooded stream valleys along Cub Run and Big Rocky Run break up the subdivisions and give many homes a green backdrop.
