GTIN (Global Tracking Identification Number or Global Trade Item Number)

GTIN is the globally-unique identification number, used for trade items (goods or products). It’s used for uniquely identifying the trade items sold, delivered, warehoused, and billed throughout retail and commercial distribution channels. Unlike a UPC number, which only provides information specific to a group of products, the GTIN gives each product its own specific identifying number, giving greater accuracy in tracking.
