The printed pattern does not have a built-in expiry date — scanners read modules the same way years later. Expiration happens when the destination or the redirect service stops working.
Common expiry scenarios
- Dynamic platform subscription lapses and redirects disable
- Short-link provider deletes inactive URLs
- Campaign landing page taken down after promo ends
- SSL certificate expires on destination domain
- Static PDF removed from cloud storage
Preventing dead codes on print
- Use dynamic codes with a fallback homepage redirect
- Own your domain on critical static links
- Monitor analytics for sudden scan drops
- Set calendar reminders before platform renewals

Do QR standards include TTL?
No time-to-live field exists in ISO QR symbology. "Expiry" is always operational — link rot, account status, or deliberate pause. Plan durable campaigns with editable destinations.
