Yves Saint Laurent batch code & expiration date

Where to find your Yves Saint Laurent batch code

The Yves Saint Laurent batch code is a short, usually embossed stamp of letters and numbers — never the barcode. Here’s what it looks like on typical packaging (the code is the short embossed stamp, not the long barcode):

A genuine Yves Saint Laurent code looks like 38A301D or 38A301L or 38A301P — usually embossed, not the barcode.

The Yves Saint Laurent batch code — also called the lot code, lot number or serial number — is a short 4–8 character stamp of letters and numbers, usually embossed rather than printed in ink, and it is never the barcode. On a bottle or jar look at the base; on a tube look near the crimp/seal at the end; on a boxed perfume or fragrance check a flap or side of the box; on makeup check the underside of the compact or inside the pan.

• Bottle / jar — stamped on the base.
• Tube — near the crimp or seal at the closed end.
• Boxed fragrance — a flap or side of the outer box (and often on the bottle base too).
• Compact / palette — the underside, or inside the pan.

About Yves Saint Laurent batch codes

Yves Saint Laurent codes encode a mapped year code, a month letter and the day. The brand is owned by L'Oreal Groupe.

Real documented examples: code → manufacture date.

Most unopened cosmetics and fragrances keep for about 30–36 months from manufacture. Once opened, follow the PAO (open-jar) symbol — it usually matters more than any printed expiration date.

We've read 962 Yves Saint Laurent batch codes so far, the newest was made August 2026, and the typical Yves Saint Laurent product people check here is about 30 months old.

Can the batch code tell me if my Yves Saint Laurent is authentic? Not on its own. A code that decodes to a sensible date, printed the same on the box and on the bottle, is a good sign, but counterfeiters copy real codes from genuine packs, so a valid code cannot prove a Yves Saint Laurent product is authentic. Buy from Yves Saint Laurent or an authorised retailer, and compare the packaging, print quality, sprayer and cap fit with one you know is genuine.

Does Yves Saint Laurent expire?

Yes — like all cosmetics and fragrances, Yves Saint Laurent products have a limited shelf life. Unopened they typically last 30–36 months from the manufacture date, and the batch code above tells you how old yours already is. After opening, the PAO (open-jar) symbol — e.g. "12M" — is a better guide than any printed expiration date.

Unopened: general cosmetics guidance. Opened: general guidance by product type. A date or open-jar symbol on your pack always wins.
