GTIN given by manufacturers flagged invalid by Merchant Center

Visitor ✭ ✭ ✭

Hi All;

 

I'm seeing a recurring issue where certain products in our Merchant Center feeds keep coming back with an "Invalid GTIN value" upon being processed.

 

The GTINs have been verified several times with the manufacturers to indeed be valid. They are of the correct character length (12 digits for U.S. feed). When I try to verify one of the culprits with the Check Digit Calculator (http://www.gs1us.org/resources/tools/check-digit-calculator), linked to from Google's Unique Product Identifiers (https://support.google.com/merchants/answer/160161?hl=en) Merchant Center help page, it consistently tries to set the check digit incorrectly to a different product by the same manufacturer.

 

For example, we list the GTIN as 628370100574 for a 5-pack license of a particular software program, and the calculator tries to set the check digit to 3 instead of 4. However, this is incorrect, as the GTIN ending in 3 is for the single-license product, which we also carry.

 

What do we do in instances like these where Google flags the GTIN as inaccurate while the manufacturers insist they are correct?

 

 

 

Best Regards,

 

Brian

this sometimes happens for various reasons such as, if
the gs1 assigned values are purchased from third-parties,
or are not properly verified and not stamped as bar-codes on
the product at the factory, or the brand-manufacture has not
assigned a proper value with proper check-digits to a variant
such as a different color or a different sized package, etc.

 

the choices are usually:
(a) verify the digits with the bar-code
stamped on the product at the factory.

 

(b) submit the items with identifier_exist FALSE
and do not submit any global-trade-data -- do not
submit brand, gtin, or mpn, at all, for that item.

 

(c) do not submit such items.

Thank you, Celebird. As most of our items are drop-shipped, getting the physical item in hand typically proves difficult. I will check with our content editors to see if they can get the manufacturers to verify the bar code on the physical item and compare to the GTIN.

If these do indeed match, then I will take the identifier_exists route. Thank you for your timely response.


Best Regards,

Brian

first, you're welcome.

as an aside, drop-ship or related supply-chains
are generally not allowed for product-listing-ads.

all items must be kept physically in stock by the
merchants who sell them; or is otherwise grounds
for a disapproval or (permanent) suspension from
the program, at any time.

that said, there are other campaign-types and
ad-formats that do not have such restrictions.
