Date code & Serial number checkers
These tools read brand-specific production codes: they identify the format, estimate a likely production period, and flag obvious inconsistencies. A useful first reading — not a verdict on authenticity.

What a code can — and can’t — prove.
A date code or serial number is one element among many. Read correctly, it can indicate a likely production period, decode factory or atelier markers, and reveal obvious format inconsistencies.
On its own, it cannot establish authenticity. Counterfeits frequently carry convincing, format-correct codes, because these patterns are widely reproduced. When a code reading is not enough, the next step is a full examination of the item itself.
Reading a code isn’t enough.
Reading a code is not enough to confirm authenticity, our experts examine the item itself — the details that determine it — and issue a clear, verifiable written verdict on its conformity.
