Where Byredo stamps its code: outer box base crimp + flacon base
Julian code printed on the box base and on a clear or white sticker under the flacon.
- Read the code off the box base crimp in raking light — authentic embossing has uniform depth.
- Read the flacon base or label code and enter it above — the two must match character for character.
- Check for scraped, re-embossed or stickered-over crimps: a classic way to hide aged gray-market stock.

Frequently Asked Questions
How do I decode a Byredo batch code?
Byredo is part of Coty · Puig · Shiseido · Independent Niche Houses and uses the Coty / Puig / Shiseido Julian Pattern: [Year 1–2 digits][Julian day 001–366][Optional line digit]. Worked example: 24165 reads as 24 = 2024, 165 = Day 165 of 366 — produced June 13, 2024. Medium-High — Julian date codes; 4-digit variants carry a single year digit. 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 Byredo box and bottle?
Julian code printed on the box base and on a clear or white sticker under the flacon. Look on the outer box base crimp and the flacon base. 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 Byredo last and where can I buy fresh-batch authentic bottles in Singapore?
Unopened and stored upright below 25°C, a Byredo 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 Byredo boutiques and authorised department-store counters.
