Global Trade Item Number (GTIN)GTIN stands for Global Trade Item Number. It is a numbering system developed by GS1 System (http://www.gs1.org) for identifying trade items such as products and services. The system provides unique identification worldwide and a GTIN can be used in barcodes or as Electronic Product Codes in Radio Frequency Identification (RFID) tags.
GTIN is an umbrella term introduced to ensure consistent terminology worldwide. It is important not to confuse a GTIN with a barcode. A GTIN can be represented by 8, 12, 13 or 14 digits. The number is encoded using existing barcode symbology. The following tables show the different GTINs and the barcode used for encoding the number.
