Why Did My QR Code Stop Working?
Published
A QR that stops working has not necessarily “expired”. First distinguish a reading problem from a destination problem.
Your phone cannot read the code
Try the original file and then the printed copy. Check sharpness, contrast, the clear margin and size. A logo or damaged print can make reading harder. Try another phone before reprinting an entire batch.
The code is readable but the link fails
Use a reader that lets you copy the encoded link before opening it. Test the destination directly: a moved page, expired domain or typo can break access.
A static QR directly contains data, such as your URL. It has no expiry imposed by the generator, but the linked page must remain available. A URL on your own domain can also redirect: the domain name alone does not prove there is no intermediary.
A dynamic QR points through a redirect service. If the service or its terms no longer allow the redirect, the pattern remains readable but access to your page may stop. Check your account and the provider’s conditions before assuming payment is required.
Can you repair an already printed QR?
If you control the encoded URL, restore its page or set up a redirect on your own site. If a third-party service owns it, only that service can restore its redirect. Creating a new QR here cannot change one already printed.
Prevent the problem
A static QR often suffices for a stable link. Create one for free and scan the exported file before printing. To change the destination without reprinting, choose a dynamic service after reading its price and cancellation conditions. QR Permanent does not offer this yet.
