GTIN

Global Trade Item Number (GTIN) is an identifier for trade items developed by GS1. Such identifiers are used to look up product information in a database (often by entering the number through a bar code scanner pointed at an actual product) which may belong to a retailer, manufacturer, collector, researcher, or other entity. The uniqueness and universality of the identifier are useful in establishing which product in one database corresponds to which product in another database, especially across organizational boundaries.

GTIN-14 (EAN/UCC-14 or ITF-14): this is a 14-digit number used to identify trade items at various packaging levels.
