I'm looking for an expert to consult with on UPC codes. I've been on Amazon for 4 years and have always purchased my UPC codes from a third party. I am now having issues with adding new variations and creating new listings on Amazon.
no you can buy them from places like "barcodes mania" so you don't need to register for GS1 which is a high cost! I've used the above service and haven't had any issues with getting products registered on the Amazon Seller account. If you want any other help feel free to drop me a message. Cheers, Alex
