Does changing a QR code destination erase scan history?
Usually not. With dynamic QR services, scan history is generally associated with the QR code or its short URL, while the destination can be changed independently.
Explanation
The core idea of a dynamic QR code is that the stable identifier and the current destination are separate.
Scan events are usually stored against that stable identifier. Changing the target URL therefore changes future routing without necessarily rewriting or deleting previous analytics.
This is useful for following the full life of a printed touchpoint: launch, offer change, new landing page and later campaign updates.
However, retention periods and visible history depend on the provider and plan. Some services restrict how far back you can view data even when older data still exists.
Concrete example
A QR code receives 300 scans in September, then its destination changes in October. The dashboard can continue to show the September scans while counting the new period separately by date.
Common mistake
If you need a clean before-and-after comparison, document the change date or use different UTM parameters. A continuous history does not always separate destination changes automatically.
