The function of postal code

First, the postal code is convenient for postal delivery. Because the postal code sets a unique number for each region, the postal company can handle the mail quickly and accurately. Through the postal code, the post office can quickly judge the destination of an email according to its first few digits, shorten the delivery time and improve the delivery efficiency.

Second, the postal code is convenient for express delivery. With the popularization of express delivery service, the complicated road and building structure in the community makes it more difficult to send pieces. By using the postal code, the courier can find the delivery address more easily, improve the delivery speed and quality, and reduce the delivery cost.

Three, postal code plays an important role in statistical data. Because postal codes are related to geographical location, government departments and research institutions can make statistical analysis according to the area where postal codes belong. In this way, we can better understand the social and economic development and provide reference for formulating corresponding policies.
