A client brought in a card written with a gel pen in 2020. By 2025, the ink on the folded crease had faded to grey. Words six and eleven were guessable only with magnification and good light.

Verify soon if
You wrote the phrase under stress. After an exchange withdrawal or a timed setup window, errors are more common. A session within the first month catches them while the original device screen is still accessible.
You are about to destroy a device. Before wiping a phone or retiring a hardware wallet, confirm your backup derives the same addresses.
