Designer Collector’s Guides

Sui Generis Intelligence

Check a Serial, Date or Product Code

Enter the designer and the identifier exactly as it appears on the item. Sui Generis Intelligence applies documented designer-specific code rules and reference records where available. A matching number can provide context, but it cannot authenticate an item by itself.

Useful for documented identifiers such as Louis Vuitton date codes, Gucci style/product references, Chanel historical numeric identifiers, and designer-specific collection or production codes where Sui Generis has a supported rule.
