Nowadays almost all items that are being sent to Amazon fulfillment centers require detailed information about them. On that form, you will put your company and product details as well as your 12-digit UPC barcode number. Amazon then manually enters the information into its inventory management computer. When they scan your barcode at the register, it calls you up to your form in their system and gives you credit for the sale. Once you place your barcode onto your product, either by printing it onto a stick or placing it into the artwork of your packaging your work is done.

The presence of barcodes on your products is a significant factor in determining how quickly shipments are received and therefore how consistently your title is in inventory and available to Amazon’s millions of customers. That's why Amazon requires manufacturers and sellers to include barcodes in their products.
