Variant GTIN and MPN

Follower ✭ ✭ ☆

Hi,

 

When adding product variants to a data feed, all variants of the same product are connected by a common item_group_id while each individual variant requires its own id

 

What about gtin (and mpn, for that matter) - can these be the same value for each variant of the same product? (Assuming this is the case on the landing pages)

 

Thanks

any and all global-trade-data (brand, mpn, gtin) submitted must
be determined and assigned by the manufacturer -- not merchants.

if the manufacturer has assigned different global-trade-values (gtin or mpn)
to individual variants then, each variant submitted must have those exact,
unique, values; however, if, and only if, the manufacturer has assigned
the same global-trade-data to all variants, then any variant submitted to

google must have those same values.

generally, only physical items that are in the merchant's possession may be
submitted for shopping-ads; check the gtin or mpn value that was stamped
by the manufacturer, at the factory, on the specific, physical (variant),
item that is being sold, shipped, and submitted.

 

self-assigned global-trade-data is generally a policy violation.

yes, item_group_id is critical when submitting variants,
so that google does not consider that duplicate-items
are being submitted -- which is also a policy violation.

The variants I'm dealing with will have unique MPN's but share a GTIN. Your post answers my question nicely, Celebird. Thanks.
