Danville, CA Zip Codes: Local Map, Neighborhoods, and County Guide for 2026

Danville, CA operates under two postal codes that divide the town's distinct neighborhoods and housing markets. If you're looking at properties in the San Francisco-Oakland-Berkeley, CA metro area, you're dealing with a fast-moving market - and knowing exactly where the boundaries fall will save you a lot of wasted time.

The median home sale price in Danville sits at roughly $2,010,000 as of mid-2026. Homes spend an average of just 22 days on the market before going under contract. That's not a lot of runway to figure out which part of town you're actually buying into.

The Zip Codes Serving Danville, CA

The postal system designates two main zip codes for Danville: 94526 and 94506. They split the town roughly into western and eastern sections, each with its own property types, lot sizes, and access to local amenities.

A small number of properties on the town's edges border neighboring postal districts, but the vast majority of Danville addresses fall into one of these two codes. When you're searching online portals or setting up MLS alerts, these are the two numbers that capture essentially all available inventory.

Breaking Down Danville's Zip Code Areas

The two postal codes cover genuinely different parts of town - different development histories, different lot sizes, different feels. These postal boundaries help you line up your search with what you actually want out of a property.

The 94526 Zip Code Boundary

The 94526 zip code covers the western portion of Danville, including the downtown sector and the historic Oak Tree in Downtown Danville.

If you want closer proximity to commercial centers and the main transit corridors running through the area, this is where you'll spend most of your time looking.

The 94506 Zip Code and Blackhawk

The 94506 zip code covers the eastern side of Danville, extending outward toward the surrounding hills and into the larger residential developments out that way.

The defining feature here is Blackhawk - an exclusive, gated luxury community with two championship golf courses at Blackhawk Country Club. Buyers after larger private lots or golf course access tend to anchor their search in this zip code, and you'll see why the moment you pull up a map.

Mapping Danville Neighborhoods by Zip Code

A boundary map makes the geography click immediately. Mount Diablo - a 3,849-foot peak and the most prominent landmark near Danville - shapes the eastern edge of the 94506 boundaries. The western 94526 area runs closer to the valley floor and the primary highway routes.

When you're scrolling through available listings, you'll notice that properties in the eastern foothills tend to come with more acreage. The downtown grid in 94526 is denser by comparison, which isn't a knock - it's just a different product. Depends entirely on what you're after.

Contra Costa County and the Surrounding Metro

Danville sits in Contra Costa County, CA, and functions as one of the more prominent residential hubs within the San Francisco-Oakland-Berkeley, CA metro area. Property taxes, assessments, and local municipal services all run through Contra Costa County offices. If you're relocating from elsewhere in the Bay Area or coming from out of state, your property records get filed with the county seat, not the town itself.

Telephone Area Codes in Danville

Phone numbers in Danville use the regional area code assigned to this section of Contra Costa County. When you're setting up utilities, internet service, or a business line, that's the prefix you'll get. Since Danville sits within the broader San Francisco-Oakland-Berkeley, CA metro, you'll routinely dial several different area codes to reach adjacent cities - the local code covers Danville and a handful of neighboring towns in the valley.

Finding Your Full 9-Digit Postal Code

94526 and 94506 handle general mail and real estate searches just fine, but official documents often require a full nine-digit ZIP+4 code. The United States Postal Service adds those extra four digits to pinpoint specific delivery routes, street segments, or individual buildings.

If you're setting up a county tax profile or working through mortgage paperwork, use the USPS online address lookup tool to pull your exact ZIP+4. Property tax bills and legal notices need to land in the right place.

Real Estate Trends Across Danville Zip Codes

The market doesn't slow down for either zip code. As of mid-2026, local inventory sits at roughly 93 available homes - about a 2.7-month supply. The average sale-to-list price ratio is running around 100.4%, and roughly 40% of homes are selling above asking price.

Whether you're targeting a downtown property in 94526 or something near the country club in 94506, come prepared. A soft offer in this market is just a way to lose a house you liked.

No - school attendance boundaries don't align exactly with postal codes. You'll want to verify any specific address directly with the school district to confirm the enrollment zone before you rely on it.
