ZIP Codes
This Santa Clara County ZIP Code reference lists five-digit codes alongside associated city and community names. Entries are arranged in ascending ZIP Code order to help residents find a code and identify its associated location.
Finding the ZIP Code for an Address
The USPS ZIP Code Lookup supports searches by street address, city and state, or ZIP Code. For a specific destination, enter the complete mailing address, including an apartment, suite, or PO Box number where applicable. Use the recommended or recognized mailing city name returned by USPS.
This table has not been verified entry by entry against current USPS records. It is a reference list, not a confirmed complete list of active ZIP Codes or USPS-approved city names. Current status and delivery type are not identified for individual entries. Confirm the ZIP Code for the complete destination address before mailing.
ZIP Code Reference by City and Community
The location column shows city and community associations. These names do not establish municipal boundaries, and a ZIP Code may be associated with locations in more than one county.

Postal Names and County Boundaries
A mailing city name does not necessarily identify the incorporated city or county containing an address. ZIP Code 94303 is associated with Palo Alto and East Palo Alto. East Palo Alto is in San Mateo County, so its appearance here does not make it a Santa Clara County municipality.
For building permits, planning questions, and other services tied to a property, use the exact street address or Assessor's Parcel Number to confirm jurisdiction. An address with a city mailing name may lie outside that city's incorporated boundaries. The Santa Clara County cities and towns guide explains the distinction between incorporated municipalities and mailing locations.
Street Delivery and PO Box Addresses
A ZIP Code associated with a community is not necessarily suitable for every address in that community. Codes may serve street delivery, PO Boxes, or particular organizations. A business or institution may also use different addresses for visitors, regular mail, and package deliveries.
For a PO Box, use the mailing address supplied by the box holder or post office. For a business or institution, confirm the address intended for the item being sent. USPS provides additional background in ZIP Code — The Basics.
