1. What Is a GTIN (Global Trade Item Number)?
A GTIN (Global Trade Item Number) is the umbrella term created by GS1 to describe the family of universal product identification numbers used worldwide.
While people often use "UPC", "EAN", and "barcode" interchangeably, the GTIN is the actual unique number, and the barcode is the printed visual symbol.
