Navigating the Greenwich, CT zip codes is essential for understanding the town's distinct neighborhoods and their corresponding real estate markets. The primary zip code is 06830, which covers most of the town, while 06831 is designated for PO boxes at the central post office. 06807 is a unique code shared with the Cos Cob area. The value of a property, its tax assessment, and even its community feel can be directly influenced by its specific zip code location within Greenwich.
Greenwich operates primarily under the 06830 zip code, which encompasses the downtown area, the prestigious backcountry estates, and neighborhoods like Riverside and Old Greenwich. The United States Postal Service (USPS) assigns 06831 exclusively for PO Box deliveries at the main post office facility. The 06807 zip code is particularly important as it is shared with the Cos Cob neighborhood, a distinct and highly sought-after community within Greenwich. Understanding these boundaries is the first step in a targeted property search, as each area offers a different lifestyle and price point. For instance, properties in the 06830 zip code can range from historic colonial homes to modern waterfront estates.
The zip code in Greenwich serves as a strong indicator of property value. 06830 is one of the most recognized zip codes in the United States for luxury real estate. Within this code, prices can vary significantly between neighborhoods like mid-country and backcountry, but the zip code itself carries a premium. The 06807 (Cos Cob) area often presents a slightly different market, sometimes offering more variety in housing styles and potentially more accessible entry points into the Greenwich real estate market, while still providing excellent amenities and schools. It is crucial to analyze recent sales data within the specific zip code and even the micro-neighborhood to accurately gauge current market value.

|---|---|---|
| 06830 | Downtown, Backcountry, Riverside, Old Greenwich | High-value luxury market, diverse architectural styles. |
| 06807 | Cos Cob | Slightly more varied price points, strong community feel. |
| 06831 | PO Boxes Only | Not applicable to residential property addresses. |
In Connecticut, local governments, including Greenwich, rely heavily on property tax to fund public services. Your property's assessed value, which is influenced by its location within a specific zip code and neighborhood, directly determines your tax bill. Property tax is an annual ad valorem tax calculated as a mill rate against your home's assessed value. Furthermore, essential services like school districts, trash collection, and emergency services are administered based on your municipal address. While the zip code helps with mail delivery, it is your specific street address that ultimately determines the exact public schools your children will attend and the local services you receive.
When searching for a home in Greenwich, use the zip codes as a starting filter on real estate portals. However, go a step further by researching each neighborhood within the 06830 and 06807 zip codes. Drive through the areas at different times of the day to get a genuine feel for the community. Consult with a local real estate expert who has deep knowledge of the nuances between, for example, a property in central Greenwich (06830) versus one in Cos Cob (06807). They can provide insights into future development plans, community trends, and how these factors might influence long-term property values within each specific area.
In summary, the Greenwich CT zip codes—primarily 06830 and 06807—are more than just mailing addresses; they are key indicators of real estate market dynamics. Understanding the boundaries and characteristics of each zip code will empower your property search and help you make a well-informed decision. Always verify school districts and municipal services by your exact street address, and leverage local expertise to navigate the subtle yet important differences between Greenwich's prestigious neighborhoods.
