Why Your QR Code Is Not Scanning (Fix Guide)

Quick diagnosis checklist

Before reprinting anything, test your code on at least two phones (iPhone and Android), in good light, at normal distance.

Top reasons QR codes fail

• The code is too small for the viewing distance.
• Low contrast (light code on light background).
• Logo or styling covers too much of the pattern.
• Blur from low-resolution export or poor print quality.
• The destination URL is broken or blocked.

How to fix a non-scanning QR code

1. Increase size and contrast.
2. Add white quiet space around the code.
3. Re-export at higher resolution.
4. Test the destination URL directly.
5. Test again across multiple devices.

Print-specific tip

If this code is on packaging, posters, or signs, prioritize reliability over heavy styling. One failed scan can cost a conversion.

Need a reset?

Start fresh with a clean, high-contrast code and test before printing at scale. Create a new QR code. You can also review How to Scan a QR Code or contact Help & Support.
