Yes. China uses a nationwide six-digit postal code system managed by China Post. This FAQ explains how Chinese zip codes work, how to read each digit, and where to search for provincial, city, and district postcodes.
China's six-digit postal codes follow a hierarchical pattern. Understanding the digits makes it easier to validate addresses and route shipments correctly:
For example, the Beijing CBD zip code 100020 indicates Beijing (10), urban area (0), and the Chaoyang District zone (020).
Every China postal code contains exactly six digits. There are no letters or hyphens, and leading zeros are significant when present.
China Post officially uses the term “postal code,” but international shippers often refer to the same six-digit number as a “ZIP code” or “postcode.” They mean the same thing.
Use our search tools to look up a postcode by city name, district name, or the number itself. Popular lookups include Beijing 100010, Shanghai 200001, Guangzhou 510630, and Shenzhen 518048.
Yes. Couriers and China Post require the correct six-digit code on parcels and letters. Including it speeds up automated sorting and last-mile delivery.
