How to use zip codes to sort letters

The value of information depends on how quickly it is transmitted. Without speed, information loses its value and benefits. Therefore, in order to meet the needs of the majority of users to speed up the speed of information transmission, speed up the processing speed of mail, and at the same time, in order to improve the modernization level of China's postal service, the Ministry of Posts and Telecommunications decided to implement the postal code system.

1) It is beneficial to speed up the processing of letters. In the process of delivery, the letter is generally sorted twice. If the sorting is done by machine, it can be 10 times more efficient than manual sorting.

Therefore, the implementation of postal code is the basic condition for the realization of postal mechanization and automation, that is to say, the implementation of postal code is to realize the automation of letter sorting, and the automation of letter sorting is to speed up the transmission of letters.

2) It is conducive to improving the quality of communication. Our country has a vast territory, complex place names, not only similar, similar place names, but also a lot of duplicate names, it is easy to make mistakes. In addition, the address on the envelope of some users is not standardized or sends letters to government agencies, only writes the name of the unit, does not write the detailed address, etc., which brings great difficulties to the postal sorting work, so that the letter can not be delivered in a timely and accurate manner.

3) It can reduce the number of missing mails. Over the years, due to the unclear writing of the addressee and sender of the letter, the post office has repeatedly forwarded, tried to deliver, and the mail that cannot be delivered and returned has increased unabated. The emergence of this situation increases the amount of labor for the post office, and for the user, the money is spent, and the work is not done or the task is wrong.

If the sender writes the postal code on the envelope, even if the address is not clear, the post office can minimize the delivery scope of the letter according to the code, so that the user will suffer less or no loss.

I've been to the Postal Mail Processing Center, so I'll talk about it. Letters are queued up through a conveyor belt, there are many passages, there is a reader in front of each channel, the letter is transmitted vertically, after arriving at each reader, it will read the first few digits of the postal code, if it is compliant, the switch in front, similar to the switch of the railway, will open, and the mail will be imported into this fork, and it is possible to continue to divide it into two or three points, and then finally fall into a large basket of the corresponding channel, so that the mail in this basket is delivered to a place. Then pack it up and send it away.

Summary. Hello, happy to answer your questions! <>

At the time of handling postal letters, the difference between manual sorting and automatic sorting was that automated sorting equipment could sort goods continuously and in large quantities. Due to the use of large production line automatic operation mode, the automatic sorting system is not limited by climate, time, human physical strength, etc., can run continuously, at the same time, because the automatic sorting system sorts a large number of pieces per unit time, the sorting capacity of the automatic sorting system is continuous operation for more than 100 hours, 7000 pieces of packaged goods can be sorted per hour, if manual is used, it can only sort about 150 pieces per hour, and the sorting personnel can not work continuously for 8 hours under this labor intensity.

At the time of handling postal letters, the difference between manual sorting and automatic sorting was that automated sorting equipment could sort goods continuously and in large quantities. Due to the use of large production line automatic operation mode, the automatic sorting system is not limited by climate, time, human physical strength, etc., can run continuously, at the same time, because the automatic sorting system sorts a large number of pieces per unit time, the sorting capacity of the automatic sorting system is continuous operation for more than 100 hours, 7000 pieces of packaged goods can be sorted per hour, if manual is used, it can only sort about 150 pieces per hour, and the sorting personnel can not work continuously for 8 hours under this labor intensity.

Starting from the aspects of time, efficiency, effectiveness, customer situation, and commodity variety, we compare the differences between manual sorting and automatic sorting in postal mail processing.

1.High sorting efficiency. The automatic sorting system can run continuously without the limitation of climate, time, human physical strength, etc., and at the same time, due to the large number of sorting pieces per unit time, the automatic sorting system can run continuously for more than 100 hours, and can sort 7,000 packaged goods per hour, which is several times the labor efficiency.

2.High accuracy. The sorting system can store data when it is working, and the data storage is mainly to ensure that the goods are sorted correctly and that the sorted goods will not be lost.

When sorting goods manually, sorting errors often occur, or goods are lost, resulting in various problems in the sorting work. The use of automated equipment to sort goods can improve the accuracy and safety of goods sorting. 3.

Reduce costs, reduce staff and increase efficiency. Automated sorting reduces a lot of labor costs for enterprises, helps enterprises improve their working methods, and makes it more convenient and efficient for enterprises to manage goods. In addition, with the reduction of labor, enterprises can spend less on the management of sorting operators, and can devote more energy and resources to management and operation, thereby improving the overall efficiency of the enterprise. ​

The implementation of the postal code requires the support and cooperation of the majority of users, so when sending mail, it is necessary to write the recipient's postal code correctly and standardly. If you don't know the other party's zip code, you can go to the local post office through the multi-** microcomputer or zip code book for inquiry, or you can query through the special service ** The first 2 digits represent the province (municipality directly under the central government, autonomous region).

The first 3 represent postal districts.

The top 4 represent counties and cities.

The last 2 represent the delivery bureau and the office.

The first two refer to provinces (municipalities and autonomous regions), such as 10 is Beijing and Zhejiang is the same place;

The first three refer to the "postal district", which is basically the same as the prefecture-level city, such as 324 refers to Quzhou, Zhejiang, and 315 refers to Ningbo;

The first four generally refer to counties (districts), such as 3241 refers to Jiangshan in Quzhou, Zhejiang, and 3240 refers to the level of Quzhou City, Zhejiang (with two districts);

The last two refer to specific post offices and offices (delivery offices), such as 324115 refers to the Jiangshan Maosaka Post Office in Quzhou, Zhejiang, which is responsible for the delivery task of Fenglin Town, Jiangshan City.

The first two digits are provinces (or municipalities directly under the central government), the middle two digits are cities, prefectures, and counties, and the last two digits are townships.

Postal codes are one of the necessary conditions for the automation of mail processing, which enables the automatic identification of mail addresses, especially the addresses of mail delivery offices, and at the same time promotes the standardization of envelopes, thus laying the foundation for the automation of sorting.

The implementation of postal codes has also improved the speed and quality of manual sorting, and it can be entered according to the code, and there is no need to memorize the complex mail transfer relationship. At the same time, the postal code can be cross-checked with the text and place name, reducing the problem of difficult mail due to unclear address.

Since July 1980, China has officially implemented postal codes in the country. It adopts the four-level six-digit code compilation method, that is, it is composed of four levels with six-digit Arabic numerals. The first two digits indicate provinces (autonomous regions, municipalities directly under the central government).

The third represents the postal area of the province: the fourth represents the county (city) in the postal area, and the last two represent the post office and its delivery office.

The implementation of the postal code requires the support and cooperation of the majority of users, so when sending mail, it is necessary to write the recipient's postal code correctly and standardly. If you don't know the other party's zip code, you can go to the local post office to inquire through the multi-** microcomputer or zip code book, or you can query through the special service**.

Then pack it up and send it away.

Figuratively speaking, it is like a big tree, where letters flow from the root to the top, choosing which leaf to flow to according to the path.

I don't know.

Think for yourself, I have this assignment too.

I was about to ask you.

Each region has its own zip code.

Don't understand what you're going to do......
