Barcodes Saver’s codes originate with the UCC (now known as GS1-US), and will be accepted by a vast majority of retail stores around the globe. This is because our barcodes are form the same original numbering system. However, we always encourage you to contact retailers you intend to stock and make enquires about their barcode policies before making a purchase with us. We also keep an up to date information page about known retailer restrictions. No barcode re-seller can guarantee universal acceptance. This is because retailers can set guidelines and policies at their own discretion. That said we have thousands of clients using our barcodes in stores globally without any issues.
