How many GS1 GTINs™ do I need when I have a product with many sizes and colours?

Each product variation needs its own GS1 GTIN™. “Variations” means each size, each colour, each combination of sizes and colours. For example, if you sell a one-size T-shirt in three colours, you’re selling three variations, so you need to assign three different GS1 GTINs™. If you use the same number for all the T-shirts, you won’t know which colour to send to your customer. • Not sure how many GTINs you need?
