Postal Code Rules of China

Postal code is a scheme to realize automatic sorting of letters, because computers can't recognize Chinese, but they can recognize numbers. By coding each area, you can quickly sort it by computer. Of course, the finer you write, the better.

China postal code adopts four-level six-digit coding structure. The first two figures represent provinces (cities, autonomous regions); The first three digits indicate the postal area; The first four digits represent counties (cities); The last two digits indicate the office.
