Instabarcode.com does not provide GS1 registration for barcodes or barcodes starting with the 890 series. Before purchasing, please verify with your retailers and online platforms that GS1 registration or an 890-series barcode is not a mandatory requirement for product acceptance. Instabarcode.com is not responsible if a retailer or online platform later rejects a barcode due to GS1 registration requirements. We strongly recommend confirming barcode acceptance policies in advance.
