I want to dropship from CJ Dropshipping to eBay, but I can’t find the UPC code for the products. How can I overcome that?

ebay has started removing adverts without Barcodes. if you don’t find the UPC code i suggest to buy cheap one from https://codesforamazon.com/product-category/barcodes/upc-barcodes/

As it will help you to have a stable listing which will not be removed by eBay

also it will help you to save your listing from copy cats as per different UPC number.

Lastly you can launch under your own brand at ebay and amazon the same item with the help of these codes.

Also your item at ebay will come up in more searches as new product added then your competitors.
