Composition and Significance of Postal Code The postal code currently used in China is a "four-level six-code" system, that is, each group of codes consists of six Arabic numerals. The first two digits of the six figures represent provinces, autonomous regions and municipalities directly under the central government, the third represents postal areas, the fourth represents county and city post offices, and the last two digits are the number of the delivery office. Each region has a different code.

Postal code is the product of the development of postal business and postal technology. In the early 1950s, with the development of economy and the progress of science and technology, due to the increase of postal business in some advanced countries, the traditional manual operation could not meet the needs of the situation, and automatic equipment such as letter sorting came into being.
