A new list of the most expensive zip codes in the nation has several Long Island towns right near the top.

Real estate data platform, PropertyShark, released a 2026 ranking of the top 100 locations in the U.S. based on median sale prices.

Sagaponack came in second in the country at $7.35 million, leading New York for the tenth time, after a 24% year-over-year increase, according to the research company.

A total of three East End municipalities cracked the top ten, with Bridgehampton taking the #4 spot at $6.15 million and Water Mill ranking seventh at $5.75 million.

Ahterton, California reclaimed #1 and broke a record, with $10.73 million, marking the first-ever eight-figure median sale price, PropertyShark says.

Bridgehampton not only set a new record high, but also more than doubled their number, +114%, compared to just last year.

Additionally, four Nassau locations also made the list, with Old Westbury ranking at #44, Great Neck at #67, Mill Neck at #86, and Manhasset sliding in with #98, according to the data.

Still, PropertyShark says Suffolk County remained strong as the main luxury real estate market in New York, as Amagansett, Wainscott, Fishers Island, Quogue, Southampton, Sag Harbor, and East Hampton all made it onto the list of 100.
