The Serial Shipping Container Code (SSCC) is an 18-digit GS1 Identification Key used to identify a logistic unit. The SSCC is different from the GTIN, as the SSCC acts as a license plate to track a shipment of logistics units through the supply chain. The GTIN uniquely identifies trade items (products and services).
It is possible for a trade item, such as a pallet, to be a trade item AND a logistic unit, so both a GTIN and an SSCC may be used. The SSCC is encoded in the GS1-128 barcode and included on the GS1 Logistics Label (a sample is shown here), making it possible to track the logistic unit in transit, and locate this unit within a storage area or warehouse.
