Extended data:
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.
American coding rules: Zip code is a registered trademark of the United States Postal Service. The first digit of the zip code represents the state of the United States, the second and third digits together represent a region (possibly a big city), and the fourth and fifth digits represent more specific regions, such as small towns or areas of the city. The new postal coding system developed by Japan Post was put into use on February 2nd, 1998. The purpose of developing the system is to meet the needs of the expanding postal mechanization operation, improve the operation efficiency and ensure to provide users with stable, cheap and high-quality services.
Its main features are: the number of postal code digits is 7, and the character "-"is used between the first three digits and the last four digits; Text structure: all numbers are used; The connection between the old and new postal code systems: three or five digits in the old code are taken as the first digit of the new code; The particularity of the new code: every small part of the address (such as cho and oaza) is designated as a number, which is connected after the existing postal code. Large enterprises and other business centers can have special codes.
