A Complete Guide for Buyers:
If you recently bought a Chanel bag and couldn't find a hologram sticker or authenticity card, don't panic. You're likely holding a newer model that uses Chanel's latest innovation in luxury authentication: the microchip.
Since 2021, Chanel has quietly revolutionized the way its bags are authenticated, moving from physical serial stickers and cards to embedded NFC microchips. But what does this mean for you as a buyer? And how can you still verify authenticity confidently?
In this guide, we'll walk you through the history, the reasons behind the change, and — most importantly — how you can authenticate Chanel microchip bags today.
The Shift — From Serial Stickers to Microchips
Before 2021, Chanel bags came with two main features to prove authenticity:
- A serial number sticker inside the bag (used since the 1980s)
- A plastic authenticity card that matched the serial code
These were widely used by resellers and buyers alike. But they weren’t foolproof. Stickers could fade or peel. Cards could be lost, swapped, or faked. As counterfeiters became more advanced, Chanel needed a more secure and future-proof solution.
It was only in April 2021, with the launch of the 21A collection, that Chanel began embedding microchips directly into its handbags. These invisible chips are now the brand’s official method for tracking and authenticating its products.
What Is the Chanel Microchip?
The microchip is a discreet NFC (near field communication) chip embedded under the inner lining of the bag. It's linked to a secure database that stores the bag's serial number, production details, and ownership history. Think of it as a digital passport — invisible, tamper-proof, and highly reliable.
Note: The chip cannot be scanned by smartphones. Only Chanel boutiques and authorized staff have access via a secure internal system.
Instead of a sticker or card, you’ll now find a metal plate inside the bag, engraved with:
- A Chanel CC logo
- An 8-character alphanumeric code
This plate is a physical indicator that the bag contains a microchip and is traceable via Chanel's internal records.
How to Authenticate a Chanel Microchip Bag in 2025
1. Visual & Tactile Inspection
Look for the metal plate inside the bag. The engraving should be sharp and match the hardware tone (e.g., gold with gold). It should be securely fastened and cleanly inset.
2. Craftsmanship Details
Check stitching quality, quilting alignment, logo accuracy, and hardware type. Any irregularities or poor finishes are red flags.
Example of an authentic Chanel bag before 2021:
3. Chanel Verification or Store Visit
Ask if the seller has had the bag verified in a Chanel boutique. Some sellers can show proof via Chanel & Moi (Chanel’s aftercare service).
4. Supporting Documents
Receipts, Chanel store emails, or aftercare confirmations help support authenticity.
💡 Tip: Always request detailed internal photos showing the plate and serial code clearly.

Real Buyer Stories
One buyer on PurseForum – Chanel Authentication Thread shared their experience after buying a 21A mini flap:
“I was so confused when there was no card. But once I spotted the plate and verified it at Chanel Bond Street, I felt reassured. They confirmed everything with the scan.”
Others have found that resellers like Re-Luxry offer third-party authentication combined with visible microchip markers to reassure hesitant buyers.
Why It Matters for Resale
Resale platforms increasingly depend on microchip verification. Not only is it more secure, but it holds up better than fragile cards or stickers. Buyers are learning to trust the plate — and sellers with microchipped bags often fetch higher resale values.
At Re-Luxry, all Chanel bags go through:
- Microchip and plate verification
- Craftsmanship and quality check
- Hardware, wear, and stitch inspection
We also show high-resolution photos of the internal metal plate in every listing.
