verify
Start with a ToneProof Seal Code or public registry lookup. Signed-in users can also run a photo-based wood grain verification against the ToneProof registry.
If this instrument has a ToneProof Seal Code, enter it below to check for a public registry record.
Upload 1–2 clear photos of the wood surface to compare the grain pattern against the ToneProof registry. Optional narrowing fields can help refine photo-based verification.
Optional narrowing applies to photo-based grain verification and can help reduce false positives.
