PropertyShark ranked the top 100 most expensive U.S. zip codes, and seven of them are in Connecticut, with six of those reaching record prices. Greenwich 06870 leads the state and ranks 45th nationally with an average closed sale price of $3.04 million.
Why it matters
For Connecticut homeowners and buyers, the ranking signals how far the state's high-end residential market has climbed, with the top Greenwich zip codes now setting record prices. The results also show that the state's most expensive towns are pulling national attention, which affects what buyers across the state should expect when pricing a home or planning a move.
Greenwich 06870 posted an average closed sale price of $3.04 million, while Greenwich 06830 and 06831 averaged $2.56 million and $2.5 million. Connecticut's top-ranked zip code, Greenwich 06878, is the first in the state to surpass $3 million.
The players
PropertyShark
A real estate data and market research platform that tracks home sales and publishes market rankings.
Greenwich, Connecticut
A Fairfield County town that holds four of the top-100 most expensive U.S. zip codes and ranks as the second most expensive community in the country.
The details
PropertyShark ranks zip codes by average closed sale price, which places the results on what homes actually sold for rather than listing asking prices. Fifteen states have zip codes in the top 100, and Connecticut is one of 11 states where those zip codes reached new record prices. Greenwich holds four of the top-100 spots, making it the second most expensive community in the country behind Atherton, California. Darien ranks 60th, Norwalk 65th, and New Canaan 81st, showing that the high-price cluster extends across much of Fairfield County.

The Home Front
The ranking reflects a high-end residential market in which record closed prices are concentrated in a small number of wealthy Connecticut towns. It sits alongside national data showing that only 15 states had zip codes in the top 100, indicating how narrowly the priciest housing is distributed.
If you own or are shopping for a home in Greenwich, Darien, Norwalk, or New Canaan, pull recent closed sales for your own zip code to see how your local prices compare with these averages. Work with a licensed local agent or appraiser to understand what a record-setting neighborhood means for your specific property before making a pricing or purchase decision.
The takeaway
Connecticut's top-priced zip codes are setting records, so the most useful habit for any local homeowner or buyer is to track closed sale prices in their own zip code over time. Keep a running record of local sales and review it with a licensed agent before listing or buying.
