As we all know, the second-instance review process and requirements of Amazon platform are very strict. Once the Amazon cross-border e-commerce store fails to pass the second trial and fails to appeal successfully, it will directly lead to the store's inability to continue selling, and all previous efforts will be lost. Therefore, it is recommended that all merchants of Amazon cross-border e-commerce do not modify the credit card directly in the background if they want to change the credit card bound to Amazon account.
If you want to update the credit card bound in the store, the merchant can send an email to Amazon's official team in advance to inform them of the new credit card number, the name of the credit card holder and the expiration date of the updated credit card, and ask this team to help update the credit card. Don't modify directly in the background.
