Why am I getting an error on the UPC on Amazon when selling Walmart products?

I'm doing online arbitrage and when I try to list new listings on Amazon from products sourced from Walmart, I put in the UPC found on Walmart's website when I do ctrl+u on the product page. So I put that in, and put everything in, but Amazon said there's an error with the UPC, that it's invalid. What am I doing wrong? How can I create new listings?
