Your UPC has an invalid value.
You can visit many different websites to check if your UPC code is valid. You can control your UPC codes by using a UPC validator tool - search Google or your preferred search engine. If you know the correct UPC number, enter it within the Item Specifics section of the listing tool.
Alternatively, you can request a Product ID exception from a related marketplace to publish your listing.
