Product identification and when to change barcode numbers


Product identification and when to change barcode numbers


For over 40 years, businesses worldwide have used GTINs (Global Trade Item Numbers) to identify almost all every product sold by retailers around the world. GS1 standards provide clear guidance as to how to use GTINs to barcode point-of-sale and traded items.

One aspect of product identification which continues to cause confusion across the supply chain is which changes to products require new GTINs to be allocated. Get it wrong and you run the risk of upsetting your customers, incur relabelling costs and lose sales.

This interactive training will offer clear guidance on how your business should identify your products in the first instance, and when and why your GTINs might need to change.


The cost of not knowing this information is quite hidden in our business. Every department needs to know, not just supply chain.”
