To put it simply, product barcodes are barcodes used on products. They are generally divided into two types, one is EAN-13 and EAN-8. EAN-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. 690-692 represents mainland China, 471 represents Taiwan, and 489 represents Hong Kong SAR. The manufacturer's code is assigned to the article coding organization of each country or region. In my country, the manufacturer's code is assigned by the National Article Coding Center. Commodity codes are codes used to identify commodities. The right to assign codes is exercised by product manufacturers themselves. Manufacturers decide which Arabic numerals to use as product barcodes on their own products according to specified conditions. 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. EAN-8 product barcode refers to an 8-digit product barcode used for identification, which is composed of a 7-digit product item code and a 1-digit check character.
