My zip code is wrong. What should I do?

Write the address correctly. No problem.

Postal code is an area code, the first two digits represent provinces, the middle two digits represent cities, and the last two digits relate to corresponding districts and streets, which can improve the sorting efficiency and accuracy within the postal service.

The staff said that there was no machine scanning code before, and when the sorter saw the postal code, it would improve the corresponding sorting rate. I can't say that the zip code is not important now. For example, the automatic sorting machine is very efficient in sorting mail, but if the postal code is not filled in, if it is not recognized during automatic sorting, it will be manually sorted again. From the internal exchange of mail, the sorting efficiency will be reduced.

In addition, the postal code is a supplement to the mail address. If the delivery address on the mail is not clear, the postman can accurately deliver it to the recipient according to the postal code above. He suggested that citizens fill in the "postal code" as accurately as possible when sending express delivery. "Not only will sorting efficiency be improved, but mail may be delivered to the destination faster."

The meaning of expanding information zip code lies in quick handshake. Previously, it was difficult to retrieve the names and addresses of all parts of China, but postal codes can help locate them efficiently. But now the difficulty of retrieval is getting lower and lower, so this function is gone, which is also the main reason why people are unwilling to fill it in. However, another meaning of postal code is the handshake of cross-language name and address exchange, which is of great significance in cross-border documents.

Some citizens think that postal code is actually an incomprehensible language created for all people in different languages, and it is used to facilitate the machine to review classified mail. In a sense, postal code is an internal process, which used to be technically limited, but now it is completely handled by operators. It is not difficult to understand why sometimes the postal code filled in by the sender is vague, but the mail can still be received.
