Hi @morklavor ,
I looked everywhere but it seems there is no GTIN/EAN13/UPC12 field for a variation. Is it possible to unlock this feature or to add it ?
Out of the box, GTIN/EAN fields are not supported in WooCommerce. You can however add them through additional plugins. I recommend searching on Google for Product GTIN for WooCommerce and taking a look at the plugins for this purpose.
We haven’t heard back from you in a while, so I’m going to mark this as resolved – if you have any further questions, you can start a new thread.
