Saratoga ZIP codes at a glance
Saratoga is unusual for a Silicon Valley city: one ZIP code covers almost all of it. The Census Bureau's 2020 relationship file, which matches ZIP Code Tabulation Areas (ZCTAs) to city boundaries, puts 99.6% of the City of Saratoga's land in ZCTA 95070 and the remaining 0.4% in 95030. A ZCTA is the Census Bureau's area version of a ZIP code, so treat it as a close guide to postal routes rather than an exact match.
| ZIP | Main city | Zillow typical value (Sept 2026) | 1-year change | Share of Saratoga's land |
|---|---|---|---|---|
| 95070 | Saratoga | $3,962,763 | +4.2% | 99.6% |
| 95030 | Los Gatos | $3,515,016 | +7.6% | 0.4% |
| 95071 | Saratoga (P.O. boxes) | n/a | n/a | none |
Zillow's typical value for the City of Saratoga as a whole was $3,974,406 in September 2026, within about $12,000 of the 95070 figure, which shows how closely the city and the ZIP overlap in price.
Saratoga ZIP codes one by one
ZIP 95070: the City of Saratoga
ZCTA 95070 covers about 28.3 square miles, of which 12.7 square miles are inside the City of Saratoga, essentially the whole city: the Village on Big Basin Way, the Golden Triangle, Fruitvale, Congress Springs, Parker Ranch and the northern neighborhoods toward Cupertino. Zillow's typical home value was $3,962,763 in September 2026, up 4.2% in a year. Redfin's median sale price was $3,823,876 for the three months to September 2026, 4.4% lower than a year earlier, from 82 sales with a median of 19 days on market. Census figures (ACS 2020-2024) show 31,417 residents, 86.6% of occupied homes owner-occupied, and median household income and median rent both at the top of the Census reporting range, above $250,000 and $3,500. What to check: the school district, which varies within this one ZIP, and the CAL FIRE hazard zone for hillside addresses. See the ZIP 95070 market data for the monthly series.
ZIP 95070 outside the city limits
More than half of ZCTA 95070, about 15.2 square miles or 54% of its land, lies outside any city, mostly unincorporated Santa Clara County land in the hills. Small pieces also fall inside Cupertino (about 0.2 square miles) and San Jose (about 0.14 square miles), with slivers in Los Gatos and Monte Sereno. A Saratoga mailing address therefore does not always mean the City of Saratoga. Unincorporated parcels follow county rules for planning and building permits, and the tax rate area on the bill differs. What to check: the jurisdiction line on the Santa Clara County Assessor's record before you plan a remodel, ADU or lot split.
ZIP 95030: the Los Gatos edge
ZCTA 95030 is a Los Gatos ZIP. The Census file places about 0.05 square miles of the City of Saratoga inside it, 0.4% of the city's land, on the side toward Los Gatos and Monte Sereno. Zillow's typical home value for 95030 was $3,515,016 in September 2026, up 7.6%, and Redfin's median sale price was $3,848,869 for the three months to September 2026, from 34 sales. What to check: a home in this sliver may carry a Los Gatos mailing address while sitting in Saratoga, or the reverse, so confirm the city and school district on the parcel record.
ZIP 95071: post office boxes
Wikipedia's summary of Saratoga lists 95070 and 95071 as the city's ZIP codes. 95071 has no Census area of its own and no Zillow or Redfin home data, which fits a ZIP used for post office boxes rather than street delivery. What to check: confirm any address's ZIP with the USPS ZIP code lookup. You will not see 95071 on a home listing.
Nearby ZIP codes buyers compare with 95070

Redfin's three-month figures tell the same story for sales: 95014 at $2,849,163 and 95129 at $2,474,273, against $3,823,876 in 95070.
Which Saratoga ZIP code costs the most?
Within the city, the question is really about neighborhoods, because 95070 covers nearly everything. Zillow's neighborhood values for September 2026 range from $2,715,310 in Sunland Park and $3,025,305 in Quito to $4,727,239 in Glen Una and $5,640,056 in Fruitvale West. Between ZIPs, 95070's typical value of $3,962,763 is higher than 95030's $3,515,016, though Redfin's recent sales medians for the two were within about $25,000 of each other, so the order can flip from one quarter to the next.

How to use Saratoga ZIP code data
- Use neighborhood and street sales, not the ZIP figure, to price a home. One ZIP spans flat quarter-acre lots and one-acre hillside parcels.
- Watch the sample size. Redfin's 95070 figures rest on 82 sales over three months, and only seven of those were condos and seven townhouses; see our Saratoga condos guide.
- Check the school district by parcel, not by ZIP. Four elementary districts serve addresses in the city; our Saratoga schools guide explains how to check.
- Check the jurisdiction. City and unincorporated county land share 95070.
- Check hazards by address on the CAL FIRE Fire Hazard Severity Zone map and FEMA's flood maps.
