Do QR Codes Expire?

QR Codes Themselves Don't Expire

QR codes themselves have no expiration date. A QR code is simply a data container; the printed black and white pattern doesn't change over time. A QR code created 10 years ago can still be scanned today if physically readable.

The misconception that "QR codes expire" almost always stems from the linked URL or service having an expiration, not the QR code itself.

Three Reasons They Appear to "Expire"

The main reasons QR codes appear to stop working:

• Linked page deleted: If the URL's page was closed or moved, scanning returns a 404 error
• URL shortener discontinued: If a shortener like bit.ly was used, service termination or link deactivation breaks the connection
• Dynamic QR code subscription ended: Dynamic QR codes from paid plans stop redirecting when the subscription expires

Tips for Long-Lasting QR Codes

Tips for keeping QR codes working long-term:

• Use your own domain URL: Store a URL you control rather than depending on shortener services
• Choose static QR codes: Static QR codes store data in the code itself, independent of external services
• Maintain the linked page: When using QR codes on printed materials, don't casually delete or move the linked page
• Use redirects: If a URL must change, set up a redirect from the old URL to the new one
