SerialRisk

Superclones can pass the look test. Their serial numbers still leave clues.

How it works

SerialRisk analyses serial numbers collected from counterfeit watch listings. With 100,000+ examples on file, recurring structures and factory patterns become visible.

  1. Collect serials
  2. Find patterns
  3. Check your serial

Counterfeit serials often appear in recurring families. In this example, the serial being checked has never appeared in our dataset — but its structure matches multiple known counterfeit serials.

Listing #84,552
Listing #90,118

What a serial check can find.

Direct match
Your exact serial has previously appeared in a listing identified as counterfeit.
Pattern signal
Your exact serial has never been seen before, but its structure matches a recurring pattern found across known counterfeit serials. This allows SerialRisk to flag serials even without a direct match.
Related signals
Near-matches, suspicious character variations and other defined serial anomalies are evaluated separately. Every triggered signal is explained in the result.
