What it means

GTIN (Global Trade Item Number) is an internationally standardized 14-digit number for uniquely identifying products. Amazon requires GTIN for most categories to correctly catalog products and prevent duplicates. An incorrect or missing GTIN can lead to listing rejections, making correct usage central to successful product sales.
