The function of postal code

1, improve mail delivery efficiency

Postal code can help postal workers quickly and accurately identify the recipient's region and route, thus improving the efficiency of mail delivery. According to the data of China Post, the delivery speed of mail with postal code is more than twice that of mail without postal code.

2. Reduce the mail loss rate.

Postal code can effectively reduce the mail loss rate. If the recipient's address does not use the postal code, postal workers need to rely on manual identification of the address and judge the route and ownership of the mail according to experience, which is prone to errors. Using postal code can avoid this situation and improve the accuracy and reliability of mail delivery.
