Scanners at the till, or ‘point of sale’ are designed to read EAN-13, UPC-A, EAN-8 and UPC-E barcodes. So, which one should you choose?
Most GS1 UK members will use an EAN-13 barcode (which has been created from a GTIN-13). If your product is particularly small, however, you may need an EAN-8 barcode (created from a GTIN-8).
EAN-13s and EAN-8s are accepted worldwide. You may also come across the UPC-A barcode which is a 12-digit barcode issued in North America.
