Do QR codes expire? Scan limits, validity and how to make them last

A static QR code is just data. It will keep working as long as the destination it encodes exists — and since the data lives inside the printed pattern, no vendor can switch it off.

A dynamic code depends on a redirect service. If the provider shuts down, expires a trial, or you stop paying, the short link stops resolving and the printed code becomes a dead end. Scan caps on free plans can have the same effect.

That is the real risk to manage — not the code format itself.

When a QR provider mentions expiry, it almost never means the pattern stops working. It means one of four things, and only the last of them is a real dead end.

Scan the code from a device that has never opened it, and watch where it lands. A provider page, a 404 or a message about a paused code means the redirect is gone even though the pattern is fine.

Then check the dashboard. A code whose last recorded scan is months old is either unused or broken, and from the outside those look identical. If the campaign is still running and the counter is flat, the code is the problem.

The check costs nothing. It beats finding a dead code on printed packaging six months later.

Choose a service that keeps codes alive on its free tier, and prefer one that lets the redirect run on a domain you control. Then a code from this year can still work years from now.
