Use a GTIN that's not in the coupon range (prefixes: 98, 99, and 05)
One or more of the values you submitted for the GTIN [gtin] attribute is only used for coupons (starts with 981, 982, 983, 984, 99, or 05), and is not a globally valid value.
Make sure you submitted the globally valid value for the GTIN [gtin]attribute or leave the value blank if the product doesn’t have a GTIN.
For more information about the validation of GTINs, refer to the GTIN Validation Guide edited by GS1, the organization that maintains GTIN standards.
