Yves Saint Laurent batch code checker
Yves Saint Laurent fragrances are produced by L'Oréal, and the third character of the code is a year letter. We can narrow that letter to a few years using two facts nobody can argue with — a bottle cannot be filled before its fragrance launched, and cannot be filled after we put it on sale. We used to give a month as well. We stopped: the only source claiming to know which character carried it turned out to publish formats that do not fit real bottles.
Where Yves Saint Laurent prints the code
Ink-jetted on the base of the bottle and printed on the bottom of the box.
What the characters mean
Six or more characters. The third is a letter standing for the year; we have not established what the fourth means, and no longer claim it is a month.

Yves Saint Laurent batch code questions
Which company actually makes YSL fragrances?
L'Oréal, under licence — YSL Beauté sits within L'Oréal's luxury division. That is why a YSL code looks nothing like a Dior or Tom Ford one: it comes out of an entirely different production system, shared with other L'Oréal-owned fragrance brands.
How do I check a YSL bottle without a decoder?
Compare the code on the bottle against the code on the box — they should match. Then judge the physical bottle: the weight of the metal cap, the evenness of the spray, the crispness of the printing, and the fit of the collar. Buying from an authorised retailer remains the only reliable protection.
Will you add YSL decoding later?
Only if we can validate a rule against bottles with known purchase dates across more than one production site. We would rather leave this page honest than ship a decoder that is right for some bottles and quietly wrong for others.
Same scheme, other houses
These brands sit under L'Oréal and stamp their bottles the same way, so if you can read one you can read them all.
Try Yves Saint Laurent before you commit
Checking a batch code is usually a way of asking whether a bottle is worth the money. A Yves Saint Laurent decant answers that on your own skin, poured from a bottle whose source we log — no marketplace gamble, no full-bottle regret.
