GTIN (Global Trade Item Number)
A GTIN (Global Trade Item Number) is a unique numeric identifier assigned to a product for use in global trade and supply chains, commonly encoded in barcodes.
What is a GTIN?
A GTIN, or Global Trade Item Number, is a unique identifier used internationally to identify products in global trade. It is assigned by GS1, the global standards organization, and is commonly encoded in barcodes scanned at retail checkouts and warehouses.
GTINs ensure that every product in the global supply chain has a universally recognized identifier, eliminating confusion when trading across borders or between different systems.
Types of GTIN
- GTIN-8 — used for small retail items with limited barcode space
- GTIN-12 — the standard UPC used in North America
- GTIN-13 — the standard EAN used in Europe and globally
- GTIN-14 — used for trade units, cases, and bulk packaging
Why GTINs Matter for E-Commerce
Major marketplaces like Amazon and Google Shopping require GTINs for product listings. A valid GTIN helps match your product to existing catalog data, improves search visibility, and enables accurate price comparisons. Products without GTINs may be rejected or ranked lower on these platforms.
Frequently Asked Questions
Is a GTIN the same as a UPC or EAN?
UPC (Universal Product Code) and EAN (European Article Number) are specific formats of GTIN. All UPCs and EANs are GTINs, but not all GTINs are UPCs or EANs — GTIN is the umbrella standard.
How do I get a GTIN for my product?
GTINs are purchased from GS1, the official issuing organization. You register your company, receive a GS1 Company Prefix, and then assign GTINs to each of your products within that prefix.
