Each zip code represents what is urgently needed

China adopts a four-level six-digit coding system, the first two represent provinces, municipalities and autonomous regions, the third represents the postal district, the fourth represents the county and city, the last two represent the post office, and the last two represent the delivery area of the city, that is, the location of the delivery area.

The zip code is postal**, which is used by the United States Postal Service and is capitalized. ZIP, is an acronym for an area improvement plan, but is also intelligently thought to imply the fact that mail travels more efficiently (and therefore quickly) when the sender uses it. The basic zip code consists of five numeric numbers.

An extended zip+4 **includes five digits of the zip code plus four digits that allow mail to be served to a specific address. Zip Code is a registered trademark of the United States Postal Service.

Postal codes are numbered with the first digit representing a particular group of U.S. states, the second and third digits together representing a region in that group (or perhaps a large city), and the fourth and fifth digits representing more specific areas, such as a small town or region of the city. Major towns in a region (if possible) often get the first zip code for that region; After that, numeric commands often follow alphabetical order. Like area codes, zip codes are divided and sometimes changed, especially when rural areas become suburban.

A new postal code system developed by Japan Post was put into operation on February 2, 1998. The purpose of the system is to meet the needs of the expanding mechanized postal operations, improve operational efficiency, and ensure that users are provided with stable, cheap and high-quality services. Its main features are as follows:

Three or five digits in the old code are used as the first few digits of the new code; The peculiarity of the new code: each small part of the address (e.g., cho, oaza) is designated as a number, which is connected after the existing postal code. Large corporations and other business centers can have a special code.

To put it simply, the first two represent provinces and regions, the third and fourth represent prefecture-level cities, and the fifth and sixth represent counties and districts.

The third and fourth represent prefectures, cities, and prefectures. The fifth and sixth represent a county. A town or a neighborhood in which you live.

A postal code is a special code that represents the post office (office) where mail is delivered. It is also the communication code of residents and units within the scope of this bureau (office). The postal code consists of 6 Arabic numerals, such as 529000.

Postal code digits: the first two digits represent the province (municipality, autonomous region), the third digit represents the postal district, the fourth digit represents the county (city), and the last two digits represent the delivery area of the city, that is, the location of the delivery area.

The zip code is mainly composed of ** numbers, which are used to automate the sorting of letters, and the coding rules are four levels and six digits (province, city, county, district).
