How do I get barcodes/UPCs?
Your products need to have UPC's before sending off to Amazon. You purchase the codes separately from the supplier of your item and then you'll only need the UPC one time to create the product listing on Amazon.
Once the listing is created Amazon assigns the product their own special version of a UPC, called a FNSKU. It's pretty much the barcode system Amazon uses to keep track of their inventory, so that is what you would be placing on the packaging.
We recommend barcodes from "Barcodes Talk" (https://www.barcodestalk.com/,) but as long as they are GS1 certified you will be good to go.
We had a really great expert bonus session talking about barcodes and how to use them properly!
