Check Registry
Start with a ToneProof Seal Code to check for an existing registry record. Signed-in members can also run photo-based wood-grain verification against the registry.
Results reflect current public registry records and may include documented or verified instruments.
If this instrument has a ToneProof Seal Code, enter it below to check for a registry record.
ToneProof uses a patent-pending process to capture visible wood-grain signatures and compare them against registry records.
Use either a Seal Code or photos — not both in the same check.
Optional narrowing applies to photo-based grain verification and can help reduce false positives.
