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.
