We usually reply within two working days.
When reporting a problem
Tell us the barcode type, the value you entered (or a similar example if it's confidential), what you expected, and your browser and device. If a barcode doesn't scan, tell us the scanner or app too.
What we can't help with
- We can't issue, sell or register UPC/EAN numbers. Those come from GS1.
- We can't look up who owns a barcode. Use GS1's Verified by GS1 service.
- We can't help with problems on Amazon, Shopify or other platforms' accounts.
