Do QR codes expire? Static vs dynamic codes explained
A static QR code does not expire on its own: it stores the content directly. What it points to can still change, move or disappear.
Static and dynamic codes
A static code contains its destination or text. Once printed, its encoded value stays the same. Changing that destination means replacing the printed code.
A dynamic code commonly stores a short link controlled by a provider. The provider can change where that link leads and may provide scan analytics. The link depends on that service continuing to operate.
What can stop working
Even a static code can lead to a deleted web page, a changed Wi-Fi password, a cancelled event, or a phone number that no longer exists. Damage and poor print quality can also make the pattern unreadable.
Before committing to a large print run, test the code on more than one phone and make sure the destination is under your control for as long as you need it.
How to choose
Use a static code when the value is stable and you want independence from a redirect provider. Choose a redirect service only when changing the destination or measuring scans is worth the provider dependency and privacy trade-offs.
In short: QRnook makes static codes. They do not expire through QRnook, but their destination may change.
