Fairfield ZIP codes at a glance

Census boundary files show that no single ZIP matches the city: Fairfield's land is split roughly 40% in 94533, 39% in 94534 and 18% in 94535, with small slivers in four neighboring ZIPs.
| ZIP | Main area | Zillow typical value (Sept 2026) | Zillow 1-year | Redfin median sale (3 months to Sept 2026) | Homes sold | Census median year built |
|---|---|---|---|---|---|---|
| 94533 | Central and east Fairfield | $532,198 | -1.4% | $549,838 | 160 | 1979 |
| 94534 | West Fairfield, Cordelia, Green Valley | $687,848 | -0.5% | $687,298 | 96 | 1994 |

For the city as a whole, Zillow's typical home value was $598,419 in September 2026, down 0.9% over the year and below the June 2022 peak of $643,722. Zillow's typical value estimates the middle of all homes, sold or not. Redfin's median covers only homes that sold in the three months to September 2026, so the two columns are different measures and are not compared with each other below.
Each Fairfield ZIP code: what it covers and costs
ZIP 94533: central and east Fairfield
94533 holds most of Fairfield's people: the Census counts 78,805 residents in the ZIP area. It takes in the older center of the city and the east side toward Travis. Public buildings with 94533 addresses include the Fairfield Police Department at 1000 Webster Street, the Fairfield Civic Center Library at 1150 Kentucky Street, Armijo High on Washington Street, Fairfield High on East Atlantic Avenue, and elementary schools such as Dover, Anna Kyle, Cleo Gordon, Laurel Creek and Tolenas. About 74% of the ZIP's land is inside Fairfield. Around 6% falls inside Vacaville and about 20% is unincorporated county land, so a 94533 mailing address does not prove a home is in the city.
Zillow's typical home value in 94533 was $532,198 in September 2026, down 1.4% in a year. Redfin's median sale price for the three months to September was $549,838, flat on a year earlier, at $316.92 a square foot. 160 homes sold, with a median of 44 days on market, and 31% sold above list price. Single-family homes made up 146 of the sales at a median of $553,860. Only 8 condos sold, at a median of $265,992, and 3 townhouses at $412,001. On the same Redfin measure, the three months to September were at $579,500 in 2023, $568,000 in 2024 and $550,000 in 2025, a slow slide rather than a drop.
Census figures for the ZIP area (ACS 2020-2024): median household income $87,384, median gross rent $2,088, median owner-estimated home value $542,200, and 55.9% of occupied homes owner-occupied. The median home was built in 1979. What to check in 94533: whether the parcel is inside city limits; the school district, since both Fairfield-Suisun Unified and Travis Unified run schools with 94533 addresses (Travis Unified's Vanden High and Golden West Middle among them); and the age of the roof, plumbing and sewer lateral on homes from the 1960s to 1980s.
ZIP 94534: west Fairfield, Cordelia and Green Valley
94534 is the largest Fairfield ZIP by land, about 78 square miles, but only about 21% of that land is inside the city. The rest includes the whole of the Green Valley census-designated place and open hill and valley land in unincorporated Solano County. The city part covers west Fairfield, where Solano County Library's Fairfield Cordelia Library sits at 5050 Business Center Drive. Schools with 94534 addresses include Angelo Rodriguez High on Red Top Road, Green Valley Middle on Gold Hill Road, B. Gale Wilson on Cherry Hills Court, and Cordelia Hills, Nelda Mundy, Rolling Hills, Oakbrook and Suisun Valley elementary schools.
Zillow's typical home value in 94534 was $687,848 in September 2026, down 0.5% in a year and about $155,650 above 94533. Redfin's median sale price for the three months to September was $687,298, down 4.5%, at $344.84 a square foot. 96 homes sold, with a median of 37 days on market, and 24% sold above list. Single-family homes were 91 of the sales, at a median of $692,825. Redfin's three-month median in this ZIP was $747,000 in September 2023 and $720,000 in September 2025, so prices here have eased more than in 94533.
Census figures: 41,203 residents, median household income $140,198, median gross rent $2,677, median owner-estimated value $744,500, and 77.7% owner-occupied. The median home was built in 1994, about 15 years newer than in 94533. What to check in 94534: whether the home is in the city or unincorporated Green Valley or Suisun Valley, which changes planning rules, services and the tax rate area; HOA dues and any special tax on newer subdivisions; and the fire hazard zone for homes near the western hills.
ZIP 94535: Travis Air Force Base
94535 is the ZIP for Travis Air Force Base. Census files place about 79% of its land inside Fairfield city limits. The Census counts 3,952 residents, and Travis Unified runs Travis Elementary and Scandia Elementary on base. The Census does not report a median owner-estimated home value for the ZIP, and neither Zillow nor Redfin publishes home values for it, because homes here are base housing rather than homes sold on the open market. Median gross rent was $3,122 in the ACS estimates. If you are assigned to Travis and want to buy, the realistic search is in 94533, 94534, Suisun City or Vacaville.

Which Fairfield ZIP costs more
94534 is the more expensive Fairfield ZIP on every measure we hold: Zillow's typical value is about 29% higher than 94533's, Redfin's three-month median about 25% higher, and the Census owner-estimated value about 37% higher. The gap follows the housing stock. 94534's homes are newer, its owner-occupied share is higher, and much of it is larger-lot land around Cordelia and Green Valley. 94533 has the lower entry price, more older single-family homes and most of the city's condo and small multi-unit sales. Neither ZIP rose in value over the year on Zillow's measure, and both remain below their 2022 levels.
How to use Fairfield ZIP data when you buy
- Confirm the city and tax rate area on the Solano County assessor's parcel record. A Fairfield mailing address can be in Vacaville, Suisun City or unincorporated county land. Our Solano County property tax guide explains rates and bills.
- Ask whether the home carries a Mello-Roos or other special tax; it appears on the tax bill, not in the ZIP data. See our Mello-Roos guide.
- Confirm the school district by address with the district. In 94533 it can be Fairfield-Suisun Unified or Travis Unified.
- Price the home from recent sales on the same street or subdivision. A ZIP median mixes 1960s tract homes with newer houses.
- Use the USPS ZIP code lookup to confirm the ZIP and city name for an exact address.
