Seven of the 10 most expensive ZIP codes in the United States sit in California, which probably comes as no surprise to many Californians.

But the nation’s priciest ZIP code, 33109, lies on Fisher Island, a stone’s throw from Miami Beach.

A new ranking of the top 100 ZIP codes, as measured by home sale prices, reaffirms the pedigree of Silicon Valley, Newport Beach and the Hamptons. More than anything, though, it shows the enduring currency of a waterfront address.

Fisher Island, an ultra-exclusive enclave that no car can reach, had a median home sale price of $9.5 million in the first nine months of 2025, according to the PropertyShark ranking.

The second-priciest ZIP code, 94027, sits in Atherton, California, a Silicon Valley community that houses titans of tech. Just a year ago, it was the nation’s most expensive ZIP.

America's priciest ZIP codes: Is it all about water?

Rounding out the top 10: ZIP codes in the Hamptons and in California’s Newport Beach, Santa Barbara, Los Altos and Marin County, all addresses on or near the coast.

"The list is not all about water, but many of the most expensive ZIP codes are in coastal or island locations," said Doug Ressler, manager, business intelligence at Yardi Matrix, a sister company to PropertyShark, a real estate data website.

Newport Beach, in Orange County, California, rated as the most expensive city in the ranking, with all of its residential ZIP codes making the top 100.

Only 15 states had even one ZIP code in the ranking. As the report notes, the priciest housing markets are "overwhelmingly coastal."

Property values continue to rise in parts of coastal California, New York and Florida, even though sea levels are rising as well.

While climate risks "are increasingly acknowledged," Ressler said, "they are not yet fully reflected in property prices."

These are the 10 most expensive ZIP codes in the US
