Global Trade Item Number
Global Trade Item Numbers (GTINs) identify products or services. Product identification numbers, such as EAN/UCC-8, UCC-12, EAN/UCC-13, and EAN/UCC-14, are drawn from the worldwide system of Global Trade Item Numbers. Note: EAN/UCC-8 is not used on shipping containers. Refer to the Global Terms for a complete description of new terminology utilized in product and carton identification. The new terminology is a global approach to standardization of product and carton identification.
When placed in a database, all GTINs should be stored in the GTIN format. This preserves the integrity of each unique GTIN. In order to place EAN-8, UCC-12, and EAN/UCC-13 numbers in the GTIN format, they are right-justified and zero filled (see Table 1.3.1 - 1). To ensure uniqueness, all GTINs must be processed in their entirety.
Databases should accommodate and process all of the data keys, including the Global Trade Item Number (GTIN) data formats UCC-12, EAN/UCC-13, and EAN/UCC-14.
