My QR code doesn't scan

A checklist for codes that phones won't read.

Go through these in order. Most codes that won't scan fail on one of the first three.

  1. Contrast. The pattern must be clearly darker than the background. Light-on-dark or low-contrast colors fail on many phones.
  2. Size and distance. The code may be too small for the distance. See what size to print.
  3. Quiet zone. Leave a blank margin around the code. Text or graphics touching the edge confuse scanners.
  4. Logo. Make it smaller, or remove it to test.
  5. Print quality. Blurry or smudged prints, and shiny lamination, make modules hard to see.
  6. Content. For a link, check the address opens in a browser and starts with https://.
  7. Dynamic code paused or over the limit. If the scan opens a 'paused' page, the code was paused or its plan ended. Open it in the dashboard.

Still stuck? Send us a message with a photo of the printed code and we'll take a look.
