There's an ongoing debate in our office - GTIN vs Brand Name & MPN? Does anyone know if GTIN is absolute requirement?

global-trade-data (mpn, gtin, brand) requirements depend
on the type of physical item and the brand-manufacturer.

for example, most apparel items require only a valid brand;
for example, most other item categories require at least two
valid, proper, global-trade values;

if the proper, required, global-trade-data exists then, the
proper, required, global-trade-data must be submitted --
or is otherwise a policy violation and grounds for disapproval
or suspension from the program, at any time.

if proper, required, global-trade-data does not exist then,
identifier_exists FALSE must be submitted for such items --
identifier_exists cannot be used to circumvent the policies.

 

placeholder values are never allowed for global-trade-data --
e.g. n/a, false, none, unknown, not-found, vintage, missing, etc.

 

only the manufacturer of a product can assign valid global-trade-data.

 

brand must be of the manufacturer who actually built the product --
the merchant store (brand) name is set in the account and submitted
for all items automatically but cannot be submitted in any (feed) data.

mpn is the exact manufacturer-part-number --
private sku or similar values are not allowed.

gtin is required for media items and all items that are manufactured by
the brand-manufacturers currently listed under the designated-brands
list published by google.

 

valid gtin digits are typically stamped on the product or package,

beneath the gs1 bar-code, at the factory, by the manufacturer.

Hi, I sell digital items (printable party supplies) that do not have gtin or MPN, what should I do, the data feed says they are Insufficient product identifiers: Missing two out of three attributes. Perhaps I am using the wrong category? is there a category for digital files that not require all this information?
Thank you in advance.

for all such printable party supplies --

(1) for google_product_category use:
Arts & Entertainment > Party & Celebration > Party Supplies > Party Supply Kits
or:
Arts & Entertainment > Party & Celebration > Party Supplies

(2) submit identifier_exists with an exact value of FALSE

(3) do not submit any mpn,
do not submit any gtin,
do not submit any brand.

then, simply ignore any related warnings for all such items.

Thank you for your answer. in the template en the example the letters assigned and values do not match (in template identifier exists is in M and in the example in L, does it makes a difference?
It is because I just added the value I was going to use after the final one in the template, is this correct?
It is also saying missing shipping and taxed, should I add '0' ?
Thanks again.

first, you're welcome.

the currently specified value for identifier_exists Is FALSE
https://support.google.com/merchants/answer/188494#identifier_exists

no -- 0 (zero) is never, ever, a valid value for shipping or tax --
tax and shipping must be either (a) not submitted at all,
or (b) exactly as google has defined in their specification,

for the type of feed being submitted.

if shipping or tax is not submitted
in the feed then, the values must be
set in the merchant-center-account.

details are currently here:
https://support.google.com/merchants/answer/160162
https://support.google.com/merchants/answer/188494#tax
https://support.google.com/merchants/answer/188494#shipping

since forum-members cannot look into
any submitted data and some of this is
a bit beyond the scope of global-trade-data,
the best likely course would be to simply
contact support directly at google --
https://support.google.com/merchants/contactflow

when contacting google be certain to ask for a
merchant-center product-listing-ad specialist.

Hi,
I have a mass feed of 1,000 items - 95% of which I can add a GTIN attribute.(along with their mpn and brand that are already included in the feed) by putting the respective ebay EAN or UPC field into a third field.
But what do I put in the GTIN field for a kit of items eg made up of 5 different containers or same brand or 5 different garage hooks (ie no 1 dominant product & to match price would create false comparisons to a single product of that GTIN).
Do I leave that field blank (rather than write FALSE) or will that error supplying a 'blank' answer under the GTIN field of the Merchant Centre feed?

the unique identifier FALSE option doesn't seem to work for our situation (despite it having a brand) as I can't instruct the software not to grab the brand and mpn that it is also generated for the other 95% of products (I could leave that blank in the relevant products, but fear it will also create an error).

NB: the feed is automatically generated daily from software that takes the relevant attribute from each product on our website.

Thanks, Nicole

this is a rather old thread.

if the feed is automatically generated then, the best likely course
would be to contact whoever is supporting the software so that the
generated feed conforms to all google's current rules and policies.

currently, if a valid, correct, gtin exists and has been properly
assigned by the product's manufacturer then, a valid and correct
gtin and brand value must be submitted -- otherwise, the item-offer
cannot be submitted and must be removed from the feed altogether.

mpn also must be assigned by the manufacturer -- but is optionally submitted.

FALSE for any global-trade-data (mpn, brand, gtin) is never allowed --
FALSE is valid for the identifier_exists attribute; if the value FALSE
is used for identifier_exists for any item-offer submitted then, the

mpn, gtin, brand, must not be submitted, at all, for that item-offer.

merchant or self-assigned global-trade-data is never allowed;
valid global-trade-data (gtin, brand, mpn) can only be assigned
by an item's manufacturer -- all merchants who are selling that

item  must submit the exact same global-trade-data values.

generally, for gtin, google wants the valid gs1 bar-code digits
that are stamped, by the manufacturer, at the factory, directly
on the exact product or package, being sold and shipped --
http://www.gs1.org/barcodes/ean-upc

not following the current rules and policies
for global-trade-data risks a disapproval or
a permanent suspension, at any time.

 

as to any custom or merchant defined bundled item-offers:
bundled offers require the is_bundle attribute set TRUE
and at least one item that is featured by the merchant --
the featured item can be any item from the bundle or
an item that has a valid gtin, regardless of any price;
the is_bundle attribute set TRUE indicates that the
gtin submitted should not be used in comparisons
and so is required for all customized bundled offers.

otherwise, if no items have proper gtin within the bundle,
simply submit is_bundle TRUE and identifier_exists FALSE
and then, do not submit any global-trade-data, at all,
for that item-offer.

otherwise, without a proper is_bundle attribute and either
(a) proper global-trade-data for a merchant featured-item
or (b) identifier_exists FALSE without any global-trade-data
then, the (bundled) item-offer cannot be submitted, at all,
and must be removed from the feed altogether to avoid a
disapproval or permanent suspension from the program, at any time.

again, if the feed is automatically generated then, the best likely course
would be to contact whoever is supporting the automated software so
that the generated feed conforms to all google's current rules and policies --
typically, this may also involve changing the link landing-page on the site.

otherwise, simply contact google directly for guidance
so they can look into the submitted feed and account.

Thanks for your feedback Celebird.
It looks like generating an is_bundle attribute within each of our products and entering either TRUE or FALSE (depending on whether individual product or bundle) might be the solution.
Do you expect a FALSE uploaded in the csv feed under is_bundle does not cause a problem for individual products?
Can I list the same GTIN twice in a feed (ie once for the individual product and again for the bundle in which 1 of those products is contained)?
Thanks again, Nicole.
