For many product categories, eBay requires sellers to include product identifiers. The identifiers are:
- GTIN – e.g. UPC. EAN, ISBN
Sending Product Identifiers
The UPC set on the product home page will be sent to eBay when listing the product. If the item does not have a UPC, a value of “Does Not Apply” will be sent, which is also valid for eBay. eBay will then place the UPC into the item specifics on the eBay listing.
Hide the MPN from eBay
Some categories do not require MPN to be sent to eBay (for example jewels). However, if you have MPN entered in the product properties, it will be automatically sent to the channel, even if you are using another product identifier (as the UPC). You can disable sending the MPN in the product eBay properties or by updating the column MPNSendToEbay in bulk.
