Release Time:2016-10-20

I should not be the only one curious about what bar code is on the express list. The express company's express delivery list is printed with bar codes, one bar code by one, which must not be repeated. The express company enters the unique bar code into the system through the scanning gun to track the information of the express, mainly to track each bar code number, so as to ensure the accuracy of the express information.

The following figure shows the express orders of Yuantong and Shunfeng: (the bar codes on these two express orders are of code128auto bar code type)

 

The following figure is the express delivery list of Yunda and Shentong. (The barcodes on these two express orders are code39 barcode types)

　

Code 128 code and Code 39 code are commonly used bar code types, are widely used in the enterprise internal management, production process, logistics control system. The difference is that Code 128 can express more characters than Code 39, and the coding density per unit length is higher. When Code 39 cannot be allowed in the unit length or the coded characters exceed the Code 39 limit, Code 128 can be selected for coding. Code 128 is more spiritual than Code 39.

Moreover, the CODE128 code supports numbers, letters and symbols, and the supported characters are more flexible. The length of characters that can be accommodated in the same length barcode is longer (high density), and there is no obvious sensitivity between the length of the barcode and the length of the string. Therefore, the CODE128 code is the most widely used bar code system in the internal management system of the enterprise.
