FAQs
A barcode is the image you’ll recognise from most products that you see every day. It is the machine readable version of a Global Trade Item Number (GTIN) - the number that sits underneath the barcode - formed of black and white lines that allows lasers to read the number and automatically identify a product.
Global Trade Item Number (GTIN) – The name given to the number that uniquely identifies a product and is mostly commonly seen sitting underneath the black and white lines of a barcode. Is 12 digits in North America, but it’s usually 13 digits long in the rest of the world, or occasionally 8 digits (for very small products).

European Article Number (EAN) – The name given to the standard barcode image that represents the 13 digit GTIN on most products you buy in shops in the UK and globally, except for North America.

Universal Product Code (UPC) - The name given to the standard barcode image of a 12 digit GTIN that is commonly used in North America.
A UPC is usually a 12-digit barcode used in North America to identify most products. The rest of the world uses 13-digit EAN barcodes to identify products. However, both types of numbers and barcodes are part of the GS1 System of international standards, so both are accepted globally.
A product identifier is simply a number that allows you to uniquely identify your product.
The GS1 System of product identification ensures that the number you have given your product is unique. Retailers have been using GS1 product identifiers – GTINs - to manage their inventories for over 50 years.
Today, with 100s of millions of products now listed online on websites and marketplaces this is more vital than ever. Marketplaces use product identifiers to manage their product catalogues, so if your product is mis-numbered and has the same identifier as another product it causes a data conflict.

The EAN/UPC barcodes you see on products today aren’t disappearing any time soon. Instead, a transition is underway. Traditional barcodes and QR codes powered by GS1 will coexist for as long as there’s a need for them.
Introducing QR codes now helps future‑proof your products and prepares you for new retail, regulatory and consumer requirements, while existing barcodes continue to support core scanning at the checkout.
