At least 41 buildings in NYC have their own zip codes.
This is most common with skyscrapers, although a unique zip code isn’t about how tall a building is. In fact, it’s more about how many businesses it contains. But there are other reasons a building could have its own ZIP code.
Why do some buildings get a special zip code?
According to AMNY, cited below: “Unique ZIP codes are sometimes assigned based on the volume of mail at a particular address – and only when a ZIP+4 will not satisfy delivery, distribution, and customer requirements,” said U.S.Postal Service spokesman Xavier Hernandez, referring to the add-on code that further segments a geographic area.”
Again, size isn’t everything. The tallest building in the country, 1 World Trade Center, doesn’t have its own zip code. However, entities such as government agencies and universities do.
