Static QR codes never expire
A static QR code stores its content directly in the pattern. There's no server, account or subscription involved, so there's nothing to expire. A static WiFi, contact or text QR code will work as long as the printed code is readable. Every free code on QwikQR's generators is static.
So why do QR codes stop working?
1. The dynamic QR service ends
Dynamic QR codes send scans through the provider's redirect link. If your trial ends, your subscription lapses, or the company shuts down, the redirect can stop and the code breaks. This is the most common reason a “free QR code” stops working.
2. The link inside is broken
A static link code can't expire, but the website it points to can: the page is moved or deleted, the domain lapses, or a shared file's permissions change. The code still scans — it just leads to an error page.
3. The content changed
A WiFi code stops connecting when the WiFi password changes. A vCard shows old details after you change your number. A social code breaks if you change your username.
4. Physical damage
Fading, scratches, dirt and torn stickers can make a code unreadable, especially if it was printed small or with low error correction.
How to make a QR code that lasts
- Use a static code unless you truly need editing or tracking. See static vs dynamic QR codes.
- Link to a page you control, such as your own website, and set up redirects if you ever move it.
- If you use dynamic codes, check the provider's terms for what happens if you stop paying.
- Print durably: large enough, good contrast, laminated outdoors, with higher error correction.
- Test periodically — scan your printed codes every few months.
