GTIN is an "umbrella" term used to describe the entire family of GS1 data structures for trade items (products and services) identification. GTINs may be 8, 12, 13 or 14 digits long, and can be constructed using any of four numbering structures, depending upon the exact application. GTIN-8s will be encoded in an EAN-8 bar code. GTIN-12s may be shown in UPC-A, ITF-14, or GS1-128 bar codes. GTIN-13s may be encoded in EAN-13, ITF-14

An EAN-8 is a barcode and is derived from the longer European Article Number code.

The numbering structure is as follows:
  • T1 - Indicator digit, used for GTIN-14, "0" to "8" indicates a packaging level and "9" a variable measure item. There is however, no worldwide consensus on which number indicates which packaging level and in some countries (Germany) a leading zero is used independently from item hierarchy.

, EAN, is an expanded UPC with 13 digits, the first three are the country code. It is widely used throughout the rest of the world. A UPC formed in the United States can be transformed into an EAN by prefixing it with a zero.

The Global Trade Item Number, GTIN-14, expands to a 14th digit with the new digit providing a level of packing. An example of usage would be for a carton containing identical items. It could be identified with a GTIN carton level indicator.
