Change what a QR code points to after it is already printed.

Local businesses printing menus and table codes, brands running packaging or product codes, and agencies managing print campaigns with a lead time before launch.

Use a dynamic QR code any time the printed material will outlast a single campaign, or when the exact destination isn't finalized before print — packaging, signage, business cards, and anything printed in bulk.

For a one-time code whose destination will never need to change — say, a single event with a fixed page — a static QR code works and skips the redirect layer entirely.

Editing the destination doesn't change anything printed next to the code — if the surrounding copy no longer matches the new destination, that mismatch isn't fixed by the redirect. A scan still depends on the destination page loading correctly.
