UPC and EAN Barcode
The UPC and EAN barcodes have been in use since the 1970s to encode Global Trade Item Numbers (GTIN), which uniquely identify a product for retail checkout or tracking purposes. UPC, UCC, EAN, JAN, GTIN-8, GTIN-12 and GTIN-13, ISBN and Bookland barcodes are all created from the same symbology type, commonly known as the UPC/EAN barcode.
