Hello,  I\’m at a roadblock in the product registration process as I am asked to provide a UPC code as a form of product ID. Due to the nature of this product, being hand sanitizer, we have an UPN number instead of UPC. How do I go about this providing the UPN code in this section even though there is no option for it?    Thank you for your help in advance!
