I have brand name but not any gtin or mpn number.

I have the brand name for my product that is a second hand ring, but I don't have the gtin or mpn number. So from where I can get the number? If I do not include the brand name, and submit FALSE in "Identifier exists" attribute, then will I get again any sort of product related warning in my Merchant Center account? If I include the brand name and TRUE in "identifier exists" attribute then do I have to include the gtin or mpn number? Please help. I need to resolve the warning issue in my account.

for rings --
(1) do not submit gtin or mpn;
(2) submit the manufactures brand and identifier_exists TRUE
(3) warnings must be ignored.

for rings, there is simply no way to remove the warnings.

if you have the valid brand from the manufacturer then, that
is all that is needed for (apparel accessories, jewelery) rings --
rings do not require any gtin or mpn.

for a ring, simply submit the valid brand and identifier_exists as TRUE
for a ring, do not submit mpn and do not submit gtin.

yes, there will be warnings -- but for a ring,
all such warnings must simply be ignored.
