Six New Jersey zip codes cracked the 100 most expensive zips in the nation, according to the 10th annual ranking of the priciest zip codes in the United States by PropertyShark, a New York-based nationwide real estate data provider.
Alpine’s 07620, destination for rap stars and professional athletes, returned as New Jersey’s most expensive zip code for the ninth time in a decade, boasting a price record of $4.35 million, a mountain-peaking 31% increase year-over-year. The Bergen County destination was the 13th-most expensive zip on the list.
Among the other New Jersey entries to the list, Deal’s 07723 (22nd overall) and Short Hills’ 07078 (57) reached record highs at $3.55 million and $2.42 million, respectively. This is the seventh appearance on the PropertyShark list for Short Hills where the median sales price soared 20%.
Allenhurst’s 07711 zip joined the ranking for the first time at No. 93 with a $2.15 million median sale price. The two other New Jersey top zips were 08247 in Stone Harbor (57) at $2.55 million and 08202 in Avalon (75) at $2.36 million, both in Cape May County.
In 2025, Miami Beach’s Fisher Island (33109) became the country’s priciest zip code with a $9.5 million median sale price, marking Florida’s first No. 1 finish. At $8.33 million, Atherton, Calif. (94027) was the second-most expensive zip, ending its eight-year run as the country’s leading zip, followed by $5.93 million Sagaponack, N.Y. (11962) at No. 3.
California retained its broad dominance with eight of the 10 highest medians and a record-dense cluster in Newport Beach.
Fifteen states had zips among the 100 most expensive, most defined by coastal or island locations.
PropertyShark’s most expensive zip codes ranking draws on actual closed sales data to chart the evolution of U.S. real estate and wealth. By measuring median sale prices rather than listings, its top 100 report tracks where high-end transactions truly close, not where sellers are asking the highest prices — a crucial distinction in a year when the map of luxury housing shifted once again.
