UPC bar code is a kind of bar code formulated by the United States Uniform Coding Committee. In order to meet the demand of North America, some of China's exports to North America also need to apply for UPC barcodes. UPC barcodes are also available in standard and shortened versions. The standard version consists of 12 digits, the shortened version consists of 8 digits, which is one less than the standard version of EAN barcode, and the shortened version has the same number of digits.
Because Amazon America stands in the United States, it adopts American standards uniformly. The products produced in China have no UPC code, and the products uploaded to Amazon USA can only be purchased or generated by software.
2.ASIN code is the only product identification code automatically generated by Amazon according to upc code, which is unique in Amazon and not universal.
UPC is internationally recognized. Every product in a brand corresponds to a UPC. UPC can only apply to relevant institutions with corporate qualifications in the United States. A company can apply for many products and use it to mark the products it sells for customers to distinguish different products.
3.EAN code (English full name: European commodity number) consists of prefix code, manufacturer identification code, commodity item code and check code.
Prefix code is the code used by international EAN organizations to identify member organizations, which is 690-697 in China; The supplier code is the code assigned to the supplier by the EAN coding organization according to the prefix code assigned by the EAN; The commodity item code is coded by the manufacturer; Check the code to check its correctness.
Manufacturers must abide by the basic principles of commodity coding when compiling commodity item codes: the same commodity item must be compiled with the same commodity item code; Different commodity item codes must be compiled for different commodity items.
Ensure that a commodity item corresponds to its identification code one by one, that is, a commodity item has only one code, and a code only identifies one commodity item. China's general commodity bar code is equivalent to it.
4、GCID
The brand identifier generated internally by Amazon provides a key attribute when your brand is successfully registered in Amazon. Amazon will automatically assign a unique global catalog identifier, namely GCID, 16 characters, including letters and numbers.
With the popularity of Amazon brand, sellers without brands are basically unable to move, so they will register their own brands in Amazon and apply for brand protection.

Other words similar to the above on Amazon:
SKU is the basic unit of goods inventory in and out, which can be composed of numbers or letters in units of parts, boxes, plates, etc. Or a mixture of the two.
SKU refers to a product, and each product has a SKU, which is convenient for e-commerce brands to identify products. When a product has multiple attributes, such as different colors and sizes, there are multiple SKUs. For example, a dress has three colors, black, white and gray, and each color has different sizes of S, M, L and XL, so this dress has 12 SKUs.
On the Amazon platform, whether you create new products yourself or sell existing products, you need a corresponding SKU. The SKU of each store is not allowed to be repeated, which is the only logo for Amazon sellers to manage products, while ASIN is only the product ID of Amazon Mall for buyers. In the Amazon inventory management list, an ASIN can correspond to multiple SKUs.
