The ZIP code of a high school in Shanghai is not applicable as ZIP codes are a United States-specific postal system. Shanghai, being a city in China, does not utilize the ZIP code system. Instead, Chinese addresses are structured differently, typically including the city name, district, street name, and building number. For example, the address of Shanghai High School might be "No. 123, Shanghai Middle Road, Minhang District, Shanghai, China." This format is used for all addresses within China, including educational institutions. ZIP codes are unique to the United States and its territories, and thus, there is no equivalent for a high school in Shanghai.
