Short answer: Your QR code keeps working after most edits (destination URL, UTMs, title, tags, folder, even color/logo). You only need a new QR if you change the slug or domain, because the QR encodes the link. When you edit any of the following, your previously printed or shared QR continues to scan to the same link (no need to reprint):
  • Destination URL. Changing it does not reset analytics. The link object and its QR remain valid.
  • UTM parameters, title, folders, tags, event tracking toggle, and other link settings. These adjust behavior/metadata, but don’t alter the encoded link in the QR code you have already downloaded.
  • QR appearance (color/logo). Only the visual asset changes. The encoded link stays the same, so old prints still scan, though they won’t match your new branding.
  • Turning the QR toggle off in the editor. Previously printed images can still be scanned because they embed the branded link. To invalidate an old print, change the slug/domain or delete the link.
If you want separate reporting after a major content change, duplicate the link instead of just changing the destination.

When you must re-download (and reprint) the QR

  • You changed the slug or switched domains This creates a new public branded link. Any QR printed with the old link will no longer reach the link. Download a fresh QR and replace it anywhere it’s used.
  • Troubleshooting reminder If scans stop redirecting after a slug change, verify the link’s current URL (domain + slug), then re-download and reprint the updated QR.

Why this happens

Every ShortPen link = domain + slug → branded link (that redirects to your destination). The QR Code encodes that URL, not the long destination. So, changing the destination is safe, but hanging the domain/slug is not.
