In Amazon, barcodes are used to identify products and make it easier for customers to find and purchase them. If you are a seller on Amazon, you can include a barcode on your product listing by including the barcode number in the “Standard Product ID” field when you create your listing. This field is located under the “Product Identifiers” section in the “Add a Product” page in your seller account.
It is important to note that the barcode must be a valid, standard product identifier such as a UPC or EAN code. You can obtain a barcode by purchasing one from a barcode issuing agency or by obtaining a license to use one of the barcode prefixes reserved for private use.
