The GTIN is a numeric system that provides globally unique codes to goods and services. Related concepts include UPC, ISBN, and NDC. The GTIN describes a family of GS1 (EAN, UCC coding) global data structures that employ 14 digits and can be encoded into various types of data carriers. Currently, GTIN (Global Trade Item Number) is primarily used within barcodes, but it can also be used in other data carriers such as radio frequency identification (RFID). The GTIN is only an umbrella term to describe varying types of GS1 numbering strings. For North American companies, the UPC is an existing form of the GTIN.
