According to media reports, postal codes are basically no longer required to send things in China. Almost all courier companies don't use zip codes anymore, these companies have their own internal codes.
Now even if you send a letter to the post office, if the zip code is wrong or omitted, it can be sent accurately, as long as the address is accurate. That said, zip codes are losing their role. In the past, post offices basically monopolized the delivery business, so they all needed to rely on zip codes to locate addresses and facilitate machine sorting.
Today, private express delivery companies have taken away most of the express delivery business after entering the bureau. Therefore, postal codes are gradually no longer used in people's lives.
Speaking of the history of postal codes, it originally originated in the United Kingdom as a measure taken by the post and telecommunications sector to modernize the post. In the early 1950s, the United Kingdom began to study postcodes, and in 1959, it was piloted in the Norwich postal area.
Subsequently, European and American countries successively implemented it. After 1965, with the widespread application of machinery and equipment, the superiority of postal codes became more apparent. my country began to develop postal codes in 1974. After five years, the "National Postal Code Trial Program" was drawn up and piloted in Liaoning, Shanghai, Jiangsu and other provinces and cities in 1978.
In 1986, the country began to implement postal codes. The zip code currently used in my country is the "four-level six-yard" system. That is, each group of codes consists of six Arabic numerals, which represent the four levels of the province (autonomous region, municipality directly under the Central Government), postal district, county (city) post and telecommunications bureau and delivery bureau (district).
Originally, many domestic addresses were difficult to retrieve, and the zip code could be located quickly, but now with the development of technology, the address information can be quickly identified, so the zip code is not needed at all. The zip code may also slowly change with the development of society in the future.
