LVMH
Guerlain batch codes, explained
Guerlain has been part of LVMH since 1994 and its bottles carry a four-character production reference. Dating it is a special case twice over: the group encoding is not published and the public decoders contradict each other, and several Guerlain pillars have been reformulated repeatedly over decades — so with this house the era of a bottle usually matters more than its month.
We do not return a date for Guerlain. Enter a code and we will tell you exactly why, and what to check instead.
Where Guerlain prints the code
On the base of the bottle, and on the box. Guerlain's heavier decorative flacons sometimes carry it on the rear of the label instead.
What the characters mean
Four alphanumeric characters on most modern bottles. LVMH does not publish the encoding, and the public decoders contradict one another.
Why we stop there: Three mutually incompatible decoding schemes are published for LVMH fragrances. One reads the second character as a month letter running A to L; another as A to M with I skipped, which shifts every month from September onward; a third reads the code as a factory letter, a year letter and a day of the year, with no month at all — and contradicts its own year table in its own worked example. Nothing public adjudicates between them, so any date we returned would be a coin toss across a third of the calendar.
Guerlain batch code questions
Why does the batch year matter more for Guerlain than other houses?
Because Guerlain's classics have long production histories and have been reformulated as materials were restricted or replaced. Shalimar, Habit Rouge and Mitsouko from different decades can smell meaningfully different. For collectors, the batch code is less a freshness check than a way of placing a bottle in the right era.
My vintage Guerlain has no batch code at all — is it fake?
Not necessarily. Systematic batch coding on consumer packaging is relatively recent; genuinely old Guerlain bottles often carry no production code, or only a moulded number in the glass that is a bottle-mould identifier rather than a date. Absence of a code on a clearly vintage flacon is normal.
Where is the code on a Guerlain bee bottle?
Usually on the base, but on the heavier decorative flacons it can be printed on the reverse of the paper label instead of the glass. If the base is clean, check the label edges and the underside of the box before concluding there is no code.
Same scheme, other houses
These brands sit under LVMH and stamp their bottles the same way, so if you can read one you can read them all.
Try it before you commit
Checking a batch code is usually a way of asking whether a bottle is worth the money. A Guerlain decant answers that on your own skin, poured from a bottle whose source we log — no marketplace gamble, no full-bottle regret.
