How Long Are QR Codes Valid?
QR codes don't automatically expire – but there are important differences between static and dynamic codes that you should know.
Static QR Codes: Last Practically Forever
A static QR code is an image file. The URL is built directly into the code. As long as:
- the image file exists
- the destination URL is accessible
...the QR code works indefinitely. There is no technical expiry date.
But be careful: The code itself lasts forever – but the destination URL might no longer exist. A 5-year-old flyer with a QR code might point to a URL that's been offline for years.
Dynamic QR Codes: Tied to Your Account
A dynamic QR code works via a redirect server. If this server is unreachable or your account with the service ends, the code stops working.
What does this mean in practice?
| Situation | QR Code Status |
|---|---|
| Account active, Pro plan running | Works ✓ |
| Account active, free plan | Works (with limitations) |
| Account canceled | Code no longer works ✗ |
| Service provider offline | Code no longer works ✗ |
How Long Do Printed QR Codes Last Physically?
The lifespan of a printed QR code depends on the print material:
| Material | Lifespan |
|---|---|
| Plain paper (unprotected) | 6–12 months |
| Laminated paper | 2–5 years |
| Sticker (indoors) | 2–3 years |
| Sticker (outdoors, UV-resistant) | 1–2 years |
| Acrylic, engraved metal | 5–10+ years |
More important than the material: Whether the URL still works.
The Three Most Common Reasons QR Codes "Stop Working"
1. The Destination URL Is Offline
The QR code itself is fine – but the website no longer exists. This happens with:
- Website relaunches with new URL structures
- Deleted pages
- Expired domains
Solution: Use dynamic QR codes and update the URL in the dashboard.
2. The Account with the QR Code Service Is No Longer Active
With dynamic QR codes, the redirect ends when the account ends.
Solution: Keep the account active or switch to static QR codes before canceling.
3. Poor Print Quality or Physical Damage
A QR code that's printed too small or has been damaged can no longer be scanned.
Solution: Maintain a minimum size of 3 × 3 cm, laminate for long-term durability.
Pro Tip: Making QR Codes Future-Proof
- Always use dynamic QR codes for printed materials
- Choose short, stable URLs as destinations (homepage rather than deeply nested subpages)
- Check regularly that all QR codes still work (once per quarter is enough)
- With QR Code Manager all your codes are centralized and you immediately see when scan numbers drop
Frequently Asked Questions
Can you set an expiry date for QR codes? In QR Code Manager you can manually deactivate QR codes. Automatic time-based deactivation after a set date is an advanced feature.
What happens if I delete my account? Dynamic QR codes will then stop working. Before deleting an account, it's advisable to convert all important codes to static ones or replace materials carrying the QR code.
Do QR codes need to be renewed? No – as long as the redirect is active and the destination URL is online, a dynamic QR code works indefinitely. Renewal is only necessary if the physical code is damaged or you want to change the URL (which you can do without reprinting).
Are there QR code standards that could become obsolete? The QR code standard (ISO/IEC 18004) has been stable and backward-compatible since 1994. It's extremely unlikely that existing QR codes will ever become invalid due to standard changes.
