What does the zip code reflect

Postal code is a special code for postal communication to realize the sorting of mail machines, and it is a necessary tool to realize postal modernization, and the ultimate goal is to improve the speed and accuracy of your letters in the delivery process, so it is important to indicate the postal code when sending letters and parcels. If you don't know the postal code of the other party (recipient), you can consult the postal code finder set up in the business room of the local post office or the postal business multi-computer query system, or you can inquire through the 11185 special service.

In order to realize the automation of mail sorting and the digitization of the postal network, and speed up the delivery of mail, more than 40 countries in the world have successively implemented the postal code system, and use it as one of the standards to measure the level of a country's communication technology and postal services. Postal code rules are not uniform across countries.

The postal code is a measure taken by the post and telecommunications department to modernize the postal service, which originated in the United Kingdom. In the early 50s of the 20th century, the United Kingdom began to study postal codes, and in 1959 it was piloted in the Norwich postal area, which attracted the attention of many countries. West Germany officially announced the four-digit postal code in 1961, becoming the first country in the world to introduce a national postal code.

Subsequently, the United States, Britain, France, Australia, Switzerland and other countries successively implemented it across the country. After 1965, with the wide application of machinery and equipment, the superiority of the postal code was more obvious, so Japan, Italy, Canada, the Netherlands and Sweden and other countries have also implemented the postal code. By the beginning of 1988, more than 50 countries and regions in the world had implemented the postal code system.

The postal code is composed of Arabic numerals, representing a special code of the post office where the mail is delivered, and it is also the code for the communication of residents and units within the delivery area of this bureau. In 1974, China began to develop China's postal code, and after about 5 years, the "National Postal Code Trial Program" was drawn up, and in 1978, it was piloted in Liaoning, Shanghai, Jiangsu and other provinces and cities. On July 1, 1980, it began to be officially promoted nationwide.

Later, due to various reasons, the implementation work was completely stopped. It was not until 1986 that the National Postal Work Conference decided to reintroduce postal codes throughout the country. China's current postal code is the "four levels and six codes" system.

That is, each group of codes is composed of six Arabic numerals, which represent the four levels of provinces (autonomous regions, municipalities directly under the central government), postal districts, county (city) post and telecommunications bureaus and delivery bureaus (districts). The first two digits of the six digits represent the province (autonomous region, municipality directly under the central government), the first three represent the postal district, the first four digits represent the county (city) post and telecommunications bureau, and the last two digits are the number of the delivery office (district).

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.

Zip code usage. The zip code is a solution to automate the sorting of letters, because the computer cannot recognize Chinese, but it can recognize numbers. Each area is coded with **, which can be quickly sorted by computer, of course, the more detailed the writing, the better.

It is conducive to mechanical sorting and improves productivity.
