The Cupertino, CA ZIP codes are 95014 and 95015. Learn which covers your neighborhood, how county taxes apply, and how to find your full ZIP+4 before closing.
The median home sale price in Cupertino, CA recently hit approximately $2,858,000. If you're buying a home near major tech campuses, you need to know exactly which areas fall within the city limits - and that starts with the postal codes. Get them right and you'll sharpen your search parameters and clarify school district boundaries in one move.
Homes here are spending roughly 16 days on the market before going under contract, and they're closing at about 104% of list price. That's not a market where you want to waste time filtering through the wrong zip codes. This guide covers the specific postal delivery zones, neighborhood boundaries, and regional details you need before you start making offers.
Cupertino operates with just two official postal codes assigned by the United States Postal Service. One handles all standard residential and commercial street deliveries; the other exists solely for post office boxes.
That single street-delivery code makes your life easier. You're not cross-referencing multiple delivery zones the way you would in San Jose or Sunnyvale - one code covers the whole city.
The 95014 zip code covers every physical street address in Cupertino. Buy a single-family home, rent an apartment, own a condo - this is your postal code. The area supports a population of roughly 61,000 to 62,600 residents, depending on which census estimate you use.
Because 95014 spans the entire geographic footprint of the city, it pulls in all of Cupertino's recognized neighborhoods. Listings in Monta Vista, Rancho Rinconada, Garden Gate, and Seven Springs all carry this same designation.
The 95015 zip code is a dedicated PO Box code with zero residential population. It routes mail to boxes physically located at the local post office facility - that's it.
You can't use 95015 as a physical address on a real estate contract or a mortgage application. If someone hands you that code for anything other than a PO Box, flag it.
The 95014 boundary mirrors Cupertino's city limits, bordered by San Jose, Santa Clara, Sunnyvale, and Los Altos. It stretches from the foothills of the Santa Cruz Mountains in the west toward the denser commercial corridors in the east - a mix of suburban tracts and major corporate campuses packed into one postal zone.
Breaking the 95014 map into sub-areas by landmarks and major traffic arteries is the most practical way to think about where you want to be.
The western edge of the 95014 map includes Monta Vista, Oak Valley, and Seven Springs/Montebello. The terrain rolls here, lots tend to be larger than what you'll find closer to the city center, and you're not far from natural reserves and hiking trails.
Commuters in this section generally use local surface streets to reach Interstate 280. The roads wind, retail is sparse, and the feel is noticeably more secluded than the eastern half of the zip code.
The eastern side of 95014 - City Center, North Blaney, South Blaney - is where you'll find Apple Park, the corporate headquarters nicknamed the "Spaceship," and the Steve Jobs Theater. Housing inventory here runs toward townhomes, condominiums, and mid-century single-family properties. You get immediate access to retail plazas, dining, and major transit routes in exchange for a denser environment.
Cupertino is located entirely within Santa Clara County, sitting in the county's western portion. Property taxes, recording fees, and deed transfers for any 95014 address run through the Santa Clara County Assessor's Office - factor county-level tax rates into your monthly budget estimates before you get too attached to a particular price point.
On a broader scale, Cupertino belongs to the San Jose-Sunnyvale-Santa Clara, CA Metropolitan Statistical Area - CBSA 41940 - which tracks economic and housing data across the entire South Bay.
The supply picture here is tight. About 72 homes were recently active on the Cupertino market, which is consistent with the low inventory and rapid sales pace you see throughout the San Jose-Sunnyvale-Santa Clara region. That number helps explain why properties are closing above asking.
The region runs an overlay system for telephone area codes. Landlines and mobile numbers in Cupertino use either 408 or 669. The 408 code is the original Santa Clara County designation; 669 was added later to handle population growth. If you're setting up utilities or a new landline, you'll most likely get a 669 number.
A standard five-digit code gets your mail to the Cupertino post office. A nine-digit ZIP+4 code takes it further - down to a specific street segment, building, or corporate mailroom. The extra four digits are how postal workers sort to the exact side of the street.
Real estate transactions, mortgage applications, and official tax documents often require the complete nine-digit code. Providing the full ZIP+4 on those forms heads off processing delays during underwriting - a small thing that matters when you're on a timeline.
The official United States Postal Service website has a free address lookup tool that validates the street name, city, and state, then generates the nine-digit code. It's straightforward and takes about thirty seconds.
Run the lookup for your new address shortly before closing. That way your change-of-address requests and utility transfers are lined up and ready to go on moving day.
The primary zip code for residential and commercial street addresses in Cupertino is 95014. The city also uses 95015, but exclusively for PO Box addresses.
Because 95014 covers the entire city, it's the only zip code available for residential living in Cupertino. The real decision is which neighborhood within 95014 fits your needs - Monta Vista in the west, City Center near Apple Park, or somewhere in between - based on your commute and housing preferences.
The 95014 zip code includes all recognized neighborhoods in the city: Monta Vista, Rancho Rinconada, Garden Gate, Seven Springs/Montebello, Oak Valley, Castlewood, Jollyman/Faria, Creston, Homestead Villa, Inspiration Heights, Stevens Creek, South Blaney, North Blaney, and City Center.
Cupertino is located entirely within Santa Clara County and is part of the larger San Jose-Sunnyvale-Santa Clara Metropolitan Statistical Area.
