The barcode itself does not matter whether it is authentic or not, what is authentic is the goods in the package;

and If the product corresponding to the barcode cannot be found on the Article Coding Center website, it is fake, because after the product manufacturer applies for the product barcode of their company at their local Quality Inspection and Quarantine Bureau, it will take a long period of time to transmit it to the National Article Code. On the center's server, if you query the barcode of the product during this period, you will not be able to find it;

The use of product barcodes has a time limit, and companies need to renew every year to continue to use the barcode, otherwise , the barcode will be deleted from the Item Coding Center website. If you query the barcode of the product during this period, you will not be able to find it.

AN-13 universal product barcode generally consists of a prefix part, manufacturer code, product code and check code.

The prefix code in the product barcode is a code used to identify the country or region. The coding authority is in the International Article Numbering Association, such as 00-09 representing the United States and Canada. 45-49 represents Japan. 690-695 represents mainland China, 471 represents Taiwan, and 489 represents Hong Kong SAR.

Manufacturer codes are assigned to article coding organizations in various countries or regions. In China, manufacturer codes are assigned by the National Article Coding Center. Product codes are codes used to identify products, and the coding rights are exercised by the product manufacturers themselves. The product barcode finally uses a 1-digit check code to verify the correctness of the 1-12th digit code from the left in the product barcode.
