Navigating postal geography in the San Francisco Bay Area can feel complicated, especially when municipal boundaries and postal zones overlap. If you're looking up Redwood City CA zip codes, you're likely trying to sort out mail delivery, real estate boundaries, or neighborhood lines across San Mateo County. Redwood City relies on five primary postal codes administered by the USPS, ranging from the downtown core up into the hills and down toward the bay.
Understanding how these specific zones break down helps you pinpoint exact locations, identify neighborhood characteristics, and handle logistics without guesswork. Let's look at the postal layout, neighborhood features, and practical details for every zone in the area.
The Complete List of Redwood City Postal Codes
Redwood City proper is covered by five primary postal codes. These include four standard residential and commercial delivery zones plus one dedicated post office box code.
- 94061: Covers central and west-central neighborhoods, stretching from El Camino Real toward the foothills.
- 94062: Covers the western hillside and mountain residential areas, including Emerald Hills and Palomar Park.
- 94063: Covers the northeastern flatlands, downtown areas near the port, and communities bordering the bay.
- 94064: A dedicated PO Box-only postal code located in the downtown core.
- 94065: Covers the southeastern waterfront communities, notably Redwood Shores.
In addition to these core zones, certain fringe addresses spill over into neighboring postal codes like 94025 (Menlo Park) or 94070 (San Carlos), depending on mail carrier routes administered by the USPS Postal Explorer.
Zone-by-Zone Breakdown and Neighborhoods
Every postal zone in Redwood City has a distinct character, geography, and property profile. Here is what defines each specific area.
94061: Central and Residential Corridors
This zone forms the backbone of mid-city residential life. It sits between Interstate 280 to the west and El Camino Real to the east. You'll find a mix of mid-century single-family homes, apartment complexes, and local commercial strips. Neighborhoods here feature traditional grid streets, mature trees, and close proximity to local schools and parks like Stulsaft Park. Commuters appreciate this zone for its balanced access to both the freeway and El Camino Real transit lines.
94062: Foothills and Emerald Hills
Moving west past Edgewood Road, the terrain shifts dramatically into the Santa Cruz Mountains foothills. The 94062 zone includes winding hillside roads, steep driveways, and expansive properties nestled among oaks and redwoods. Neighborhoods like Emerald Hills and Palomar Park sit entirely within this zone. Homes here often feature panoramic canyon or bay views, though properties require careful navigation of narrow, winding roads during winter storms.
94063: Downtown, Port, and Bay-Side Flats
The 94063 zone captures the bustling commercial downtown, historic civic centers, and the industrial working waterfront along the Port of Redwood City. Housing stock here varies widely, ranging from historic Victorians near downtown to modern townhome developments and multi-family complexes. Because this area sits flat near the baylands, parts of it require attention to local elevation and drainage maps during heavy winter weather.
94065: Redwood Shores Waterfront Living
Located on a peninsula jutting out into San Francisco Bay, Redwood Shores (94065) operates almost like its own distinct community. Built largely through master-planned developments in the late 20th century, this zone features waterfront condominiums, single-family homes lined with canals, and major corporate office parks. Levees wrap around the neighborhoods, providing walking and jogging trails with direct views of the bay and sloughs.
Common Mistakes When Addressing Mail in Redwood City
Postal sorting errors frequently happen in the Bay Area due to overlapping municipal borders. Keep these practical tips in mind to ensure your mail and packages arrive without delay:
- Don't confuse city names with postal names: Some addresses physically located within city limits might be assigned to neighboring post offices, or vice versa. Always verify the preferred city name tied to the specific nine-digit ZIP+4 code.
- Double-check PO Box designations: If you are shipping via private carriers like FedEx or UPS, they cannot deliver to USPS PO Box numbers in 94064. You must use a physical street address alternative or corporate shipping address.
- Account for Redwood Shores specifics: Mail directed to Redwood Shores should clearly list "Redwood City, CA 94065" rather than just "Redwood Shores," as the latter is a neighborhood descriptor rather than an independent USPS municipality.
