Each Cupertino ZIP code in detail
95014: Cupertino's main ZIP
95014 is Cupertino for almost every practical purpose: City Hall at 10300 Torre Avenue uses it, and so do the great majority of the city's homes, shops and offices. It is larger than the city: only about 44% of the ZIP's 64.39 square kilometers of land is inside Cupertino, and most of the rest is unincorporated county land outside any city. Zillow's typical home value was $2,957,803 in September 2026, up 2.9% in a year. Redfin's median sale price for the three months to September 2026 was $2,849,163, 6.9% lower than a year earlier, on 76 sales. Homes went under contract in a median 13 days and sold for 105.4% of list price on average. By home type, Redfin's single-family median was $3,019,238 on 58 sales, and the townhouse median $1,150,002 on 9 sales. The Census Bureau's 2020-2024 survey counts 60,932 residents in the ZIP, a median household income of $230,913 and 58.7% of homes owner-occupied. See the 95014 market data page.
95070: the Saratoga edge of Cupertino
About 0.53 square kilometers of Cupertino, the largest of the slivers, carries the Saratoga ZIP 95070, along the Saratoga border. Almost all of the City of Saratoga lies in 95070. Zillow's typical value for the ZIP was $3,962,763 in September 2026, up 4.2%. Redfin's three-month median was $3,823,876 on 82 sales, down 4.4% from a year earlier, with a median 19 days to contract. The ZIP's owner-occupied share is 86.6% in the Census data, much higher than in 95014. If a listing in Cupertino shows 95070, confirm the city on the county assessor's record, because the ZIP alone does not tell you which city's services and rules apply. See the 95070 data page.
95051: the Santa Clara edge
About 0.13 square kilometers of Cupertino falls in 95051, a Santa Clara ZIP, along the Santa Clara border. Our Zillow file has no ZIP value for 95051, so we quote Redfin only: a median sale price of $1,801,471 for the three months to September 2026, down 5.1%, on 105 sales and a median 16 days on market. That is well below 95014, because most of 95051 is Santa Clara with more condos, townhomes and apartments; Census puts its owner-occupied share at 43.9%. See the 95051 data page.
94024: the Los Altos edge
A very small area of Cupertino, about 0.04 square kilometers, sits in the Los Altos ZIP 94024 along the Los Altos border. Zillow's typical value for 94024 was $4,604,457 in September 2026, up 7.8%, the highest of the six ZIPs. Redfin's three-month median was $4,863,571 on 53 sales, and homes went under contract in a median 8 days. See the 94024 data page.
94087: the Sunnyvale edge
About 0.04 square kilometers of Cupertino uses the Sunnyvale ZIP 94087, along the Sunnyvale border. Zillow's typical value for 94087 was $2,712,454 in September 2026, up 3.5%. Redfin's three-month median was $2,821,671 on 92 sales, up 4.5% on the year, with a median 10 days on market. See the 94087 data page.
95129: the San Jose edge
95129 is a West San Jose ZIP that touches Cupertino's eastern edge. The Census file finds only about 0.005 square kilometers of overlap, so in practice very few Cupertino homes use it. Zillow's typical value for 95129 was $2,508,365 in September 2026, up 2.7%, and Redfin's three-month median was $2,474,273 on 52 sales. Because it borders Cupertino, some listings near the city line show 95129 or are described as "Cupertino adjacent"; check the assessor's record for the city. See the 95129 data page.
Why ZIP 95014 figures differ from Cupertino city figures
Because 95014 covers almost all of Cupertino, its figures track the city closely: Zillow's typical value is $2,957,803 for the ZIP and $2,957,922 for the city. The two are not identical, because the ZIP also covers land outside the city and the city has slivers in other ZIPs. Redfin's three-month median for the city ($2,848,643) and the ZIP ($2,849,163) are also within a few hundred dollars.
A ZIP code is a mail route, not a boundary. Your property tax, school district, permits and trash service follow the parcel's city and district lines, not the ZIP. For schools in particular, Cupertino is split between Cupertino Union for elementary and middle school and Fremont Union for high school, with a small corner in Santa Clara Unified. Use the district's address lookup rather than the ZIP.
Which Cupertino ZIP code costs the most?
On Zillow's figures, 94024 (Los Altos) at $4,604,457 and 95070 (Saratoga) at $3,962,763 are the most expensive ZIPs that touch Cupertino, and 95129 (San Jose) at $2,508,365 is the least expensive with a Zillow value. On Redfin's three-month medians, 95051 (Santa Clara) is lowest at $1,801,471. These are figures for the whole ZIP, and the slivers inside Cupertino are too small for their own price data. For homes inside the city, the 95014 numbers are the ones that matter.

How to use Cupertino ZIP code data
- Compare the same measure. Zillow's typical value and Redfin's median sale price are different measures. Compare Zillow with Zillow and Redfin with Redfin.
- Watch the sample size. 95014 had 76 sales in three months, enough for a stable median. Medians by home type, such as 9 townhouse sales, move a lot from month to month.
- Check the city on the parcel. For any address that shows a ZIP other than 95014, confirm the jurisdiction with the Santa Clara County assessor before you rely on Cupertino rules.
- Use comparable sales. For a price on a single home, ask an agent for recent sales on similar streets. Our Cupertino housing market page tracks the monthly trend, and our Cupertino guide covers buying and selling in the city.
