The Global Trade Identification Number (GTIN) is used to identify and mark products. GTIN is the identification number used widely in eCommerce and other digital processes in the health care industry. The GTIN is a decimal barcode, which is machine and human readable. In addition to the identification of the product, a GTIN is applied on the packaging at every packing step, e.g. product cardboard box, convenience box, shipment box, and transport box. With this, the packing hierarchy is taken care of as well, which is important in cases of single product or convenience box sales.
