GTIN Barcodes are the data carriers which serve as the vehicle for a GTIN. Today, 5 GTIN barcodes (symbologies) are commonly used to support the GTIN data structure: UPC; EAN; ITF-14; GS1-128; and GS1 Databar. Of these, ITF-14, GS1-128, and GS1 Databar employ 14-digit data structures of which the 14th character is a packaging level indicator (i.e., item or case).
Both UPC and EAN have an implied packaging level of a single item. Therefore, these GTIN barcodes support the GTIN data structure without changing the number of encoded data characters.
GTIN- 8 (EAN/UCC-8)
The table below further illustrates the relationship between GTIN, legacy terminology, GTIN Barcodes and use at point of sale. In most cases, the legacy terminology and the data carrier are called by the same name. GTIN changes this by separating the name of the data structure from the data carrier or, in this case, the GTIN Barcode (symbology).
