China postcode coding rules;

China adopts a four-level six-digit coding system, with the first two representing provinces, municipalities and autonomous regions, the third representing postal areas, the fourth representing counties and cities, the last two representing the post office, and the last two representing the delivery area of the city, that is, the location of the delivery area.

For example, the postal code "13002 1", "13" stands for Jilin Province, "00" stands for Changchun, the provincial capital, and "2 1" stands for the delivery area.

According to the characteristics of China's postal network and national traffic geography, China's postal codes are arranged in four levels and six digits. That is, on the basis of administrative divisions, six figures are adopted and classified into four levels.

The combination of the top two represents provinces, municipalities and autonomous regions; The combination of the top three represents the postal area; The top four groups represent counties and municipal bureaus; The last two digits indicate the delivery office. Six digits are connected, which is a complete set of postal codes. It contains the information that letters need in the whole sorting process.
