Before you write
- A code doesn't scan? Run it through the scannability checker first; it usually shows the problem in seconds.
- Want to change a printed code? Static codes can't be edited after printing. See Do QR codes expire? for workarounds.
- Found a scam QR code? Report it to the business where you found it and to your local fraud authority. Our safety scanner can show you where it leads.
We usually reply within two working days.
