THE GTIN standard is a GS1 Identification Key that helps identify different trade items. This internationally unique system works in assigning GTINs to business owners, giving them easy means to identify items as they make their way through the supply chain.
The use of GTINs to identify products at varied packaging levels is common. For example, a case that contains multiple units of a single item can have a unique GTIN. Data elements such as expiry dates and lot numbers may be used to identify items that come with similar usage or production traits. Once a business assigns a GTIN to any item, it serves as a unique identity that provides information about the product and it is recognizable by all its trading partners.
The GTIN standard worked in integrating different global standards into a singular numbering space. The other standards include the International Article Number (EAN), the International Standard Book Number (ISBN), a few Universal Product Codes (UPCs), the International Standard Serial Number (ISSN), and the International Standard Music Number (ISMN).
GTINs come in different lengths. The product type and the market in which it is to be sold essentially determine the length of an item’s GTIN.
The different GTIN lengths follow similar structures. They include a company’s prefix, an item reference number, and a check digit. GTIN-14 includes an added component in the form of an indicator digit. Their encoding relies on different systems.
GS1, a Belgium-based not-for-profit global organization, is responsible for developing and maintaining the GTIN standard. It has local member organizations in more than 110 countries.
GS1 was founded in 1977, as the European Article Numbering (EAN) Association. The organization now has over 90 member countries. The corresponding table lists existing GTIN data structures and their former names or legacy terminologies.
