GTIN Global Trade Item Number
The universal product identifier that powers global retail, e‑commerce, and supply chains -from a single can of soda to a pallet of goods.
What is a GTIN?
A GTIN (Global Trade Item Number) is a globally unique 8, 12, 13, or 14-digit number used to identify any trade item (product or service) that can be priced, ordered, or invoiced.
GTINs are the backbone of modern commerce - they ensure that a product is recognized the same way in a warehouse in Doha, a retailer in London, and an e-commerce platform in Singapore. Each distinct product variation (size, color, packaging) gets its own unique GTIN.
Purpose & usage
- Consumer units - individual products at point of sale (chocolate bar, shampoo bottle).
- Cases & cartons - multi-pack of consumer units for logistics.
- Logistics units - pallets (combined with SSCC).
- Digital assets - e-commerce listings, digital coupons.
- GTIN is mandatory for major retailers - (Carrefour, Lulu, Amazon, Monoprix) and e-marketplaces.
