📍Address for ZIP 666100666100

Chinese postal codes consist of 6 digits: the first 2 identify the province, the 3rd the postal region, the 4th the county/city, and the last 2 the delivery office. The system is maintained by China Post.

For cross-border e-commerce sellers, always verify the recipient's address and ZIP code before shipping, and check whether the destination is in a remote/outlying postal area — delivery costs can differ dramatically.
