Saint Laurent Authentication Guide: Serial Number and Leather Stamp

Why Authenticating a Saint Laurent Bag Requires Attention

Iconic Saint Laurent models, such as the Sac de Jour or the Loulou, are among the most sought-after pre-owned pieces, which also makes them frequent targets for counterfeiting. Rigorous verification relies on several cross-referenced clues, never just one.

The Stamp and Embossed Number

Most Saint Laurent bags feature a number embossed directly into the leather, usually near an inner seam or the clasp. The exact format and location of this stamp have evolved across collections, so its mere presence alone is not enough to guarantee authenticity.

Points to Examine

The quality of the grained or smooth leather, the regularity of the stitching, the finish of the gold or palladium hardware (often marked "YSL"), and the inner lining must be carefully examined. Poorly centered logos or overly light hardware are frequent signs of counterfeiting.
