GTIN (Global Trade Item Number)
Definition
A GTIN is the universal product identifier used across global supply chains and retail channels. Common variants include UPC (12 digits, US/Canada retail), EAN (13 digits, European retail), and ISBN (books). Every distinct SKU/variant in a DTC catalog should have a unique GTIN.
How operators actually use it
GTINs are mandatory for selling on Amazon, Google Shopping, Meta catalog ads, and most wholesale partners. Brands purchase GTINs from GS1 (the authoritative issuer) for $250-$10,000 depending on volume needs. Without GTINs, your products either cannot list or list with depressed performance on the major catalog-driven platforms. Smart brands assign GTINs at SKU creation, not as an afterthought when they hit a channel block.
Common pitfalls and honest-cost notes
Buying GTINs from resellers (Speedy Barcodes, GoldBarcodes) saves money short-term but causes Amazon and Google to reject or suppress your listings because the GTIN is registered to another company. Always buy direct from GS1 and pay the membership fee. Also: assigning the same GTIN to multiple variants (color, size) breaks every catalog feed — each variant gets its own.
