Please check with your retailer(s) prior to purchasing barcodes. The majority of retailers will accept the barcodes purchased from Australian Barcodes. However, some retailers (e.g. Amazon, Woolworths, Coles & Super Cheap Auto ) require that barcodes be purchased from or verified by the Global Standards Body. So … our barcodes will be accepted by many retailers, but not by all retailers. Check with your retailer. If you have any questions about this, or require further information, please contact us.
