Where Le Labo stamps its code: bottle label + outer box base crimp

Le Labo prints a 'compounded on' date on the personalised bottle label at the point of sale, plus the 3-character ELC code on the box base and flacon.

  1. Read the code off the box base crimp in raking light — authentic embossing has uniform depth.
  2. Read the flacon base or label code and enter it above — the two must match character for character.
  3. Check for scraped, re-embossed or stickered-over crimps: a classic way to hide aged gray-market stock.

Le Labo also prints a "compounded on" date on the bottle label — it should fall on or after the decoded production month.

Decodes are estimates from published code structures. A valid format never proves authenticity.

Frequently Asked Questions

How do I decode a Le Labo batch code?

Le Labo is part of The Estée Lauder Companies and uses the Estée Lauder Companies Pattern: [Run / plant letter][Month 1–9 / A=Oct / B=Nov / C=Dec][Year digit]. Worked example: B64 reads as B = Batch run B (2nd), 6 = June, 4 = 2024 — produced June 2024. High — 3-character ELC code used across fragrance, skincare and colour. A correctly formatted code is necessary but never sufficient proof of authenticity, because counterfeiters copy real codes.

Where is the batch code stamped on a Le Labo box and bottle?

Le Labo prints a 'compounded on' date on the personalised bottle label at the point of sale, plus the 3-character ELC code on the box base and flacon. Look on the bottle label and the outer box base crimp. The code on the box and the code on the flacon must match character for character; a scraped, re-embossed or stickered-over box crimp is a classic sign of aged gray-market stock.

How long does Le Labo last and where can I buy fresh-batch authentic bottles in Singapore?

Unopened and stored upright below 25°C, a Le Labo fragrance is a fresh batch for its first 24 months from production, sits in the maceration window to about 36 months for EDP and Extrait, and stays within tolerance to 60 months; past 60 months, check for darkened juice and sour or metallic top notes. Skincare and cosmetics should be used within 36 months of production. In Singapore, buy from retailers that disclose the batch code before dispatch — for example Beauty.net's labelled partner retailer Perfume.sg — or from Le Labo boutiques and authorised department-store counters.
