Sell my own product on Amazon

I want to sell my own product on Amazon. I already created an Amazon Seller account and got verified. Now, I dont know how to add my products as I dont have barcodes. Should I sell as generic or do I need a branding? Thanks.

ou will have to purchase the barcode and if you want to do value addition, you will still create the listing with the same barcode, no need for another. Value addition makes your product unique from other sellers And Brand Registry protects your listing from wholesalers and hijackers

Yes, you can sell as a generic or own a brand. What you are missing is the UPS barcode used to upload the listing, which you need to purchase from the GS1 website
