It is technically impossible to distinguish between a GTIN and a UPC since they are the same thing. Likewise, UPC, EAN, and ISBN are all GTINs. GTINs are numbers encoded into either UPC, EAN, or ISBN barcodes.
GTIN stands for Global Trade Item Number. More specifically, GTIN is the series of numbers associated with a barcode. An organization’s unique products are identified by GTIN codes, which are part of a larger global data structure.
GTIN-12 (UPC), GTIN-13 (EAN), and ISBN are the three types of GTINs. Although each serves different purposes, each GTIN type is a part of the GS1 System of International Standards, so they are all recognized globally.
