Can you use the same dynamic QR code on multiple materials?
Yes. The same QR code can be printed on several materials and all scans will use the same destination. However, attribution becomes difficult if every medium uses exactly the same code.
Explanation
Reusing a single QR code simplifies management because one destination change applies everywhere at once.
That approach works well when the only goal is to send people to the same content. It is less useful when you want to compare a shop window, flyer, catalogue or several stores.
For placement-level analytics, create a separate QR code for each medium while keeping the same final destination. You can then compare scan volume without changing the visitor experience.
Concrete example
A poster, flyer and business card can all use the same QR code. But three separate QR codes pointing to the same page will tell you which physical medium actually performs best.
Common mistake
UTM parameters can distinguish media only if they are different. The same QR code pointing to the same UTM-tagged URL will still produce the same source data everywhere.
