No, Amazon will only pay attention to whether the UPC code is accurate and valid, that is, it has not been used. If you apply for the UPC code for your own company, there is no problem. Please register it, such as a code. Just don't reuse it after use. Never go to TB to buy so-called UPCs. Many of these are generated by generators and are unreliable. Now Amazon is becoming more and more strict about UPCs.
