Real bag,
or a very good copy?

The tells that worked five years ago mostly do not any more, and the two biggest houses both changed how they mark bags in 2021. Here is what still holds.

The counterfeit market for handbags got good, and it got good quickly. Stitch counts, hardware weight, heat stamps and date codes are all reproduced now. Most of the advice still circulating online was written against fakes that no longer represent what is actually out there.

No single check settles it. Anyone who tells you one detail proves a bag is real is selling something. Authentication is several independent things agreeing with each other, and the moment one of them disagrees, that is the thread to pull.

Start here

What changed in 2021?

Both Chanel and Louis Vuitton replaced their old visible identifiers with embedded chips around 2021. This matters more than any other single fact in this guide, because it means the most widely repeated advice on the internet now gives the wrong answer on any recent bag.

Louis Vuitton

Before 2021
Date code stamped or heat-pressed inside
After 2021
Embedded microchip, no visible code

Chanel

Before 2021
Numbered sticker with hologram overlay
After 2021
Embedded chip, no sticker

So the first question is not what the code says. It is how old the bag claims to be, and whether the marking method matches that era at all.

Louis Vuitton

How do you spot a fake Louis Vuitton?

  1. 01

    Canvas alignment across seams

    On Monogram and Damier the pattern should run correctly across panels, and on symmetrical models it should mirror properly on both sides. Counterfeiters save material by ignoring this, and it is one of the more reliable tells left.

  2. 02

    Vachetta leather and how it has aged

    The untreated leather trim darkens from pale to honey over years of handling. It is very hard to fake convincingly. Trim that looks brand new on a bag claiming to be a decade old, or evenly darkened in a way that does not match where hands actually touch it, is worth a second look.

  3. 03

    Hardware weight and finish

    Genuine hardware has heft and a consistent plated finish. Lightweight, thinly plated or slightly yellow-looking hardware is common on copies.

  4. 04

    Heat stamp letterforms

    The font is consistent and evenly impressed. Letters that are too thick, unevenly spaced, or pressed at different depths across the line are a problem.

Chanel

How do you tell if a Chanel bag is real?

  1. 01

    Quilting that runs continuously

    The diamond pattern should continue across seams and over the flap without jumping. Getting this right wastes leather, so copies frequently do not bother.

  2. 02

    The CC lock

    The interlocking Cs have a specific overlap, and the lock turns a specific way. Both are commonly wrong on counterfeits, and both are easy to check once you know what the model should do.

  3. 03

    Leather behavior

    Caviar and lambskin behave differently under pressure and age differently. A bag described as caviar that dents like lambskin is not what it says it is.

  4. 04

    Chain construction

    Weight, the way the leather is threaded through, and how the links are finished. The chain is expensive to make properly and it is a common corner to cut.

Hermes

What is the most reliable check on an Hermès bag?

Hermes bags are hand saddle stitched, which produces a slightly irregular, angled stitch that a machine does not replicate. It is the closest thing to a single reliable tell anywhere in handbags, and it is why Hermes remains harder to fake convincingly than anything else on this page.

Beyond that, the blind stamp carries a date indicator and the individual craftsman's mark, and both have to be right for the era in placement and depth.

Everything else

What are the warning signs on any designer bag?

  • Stitching that wanders, changes angle, or has inconsistent tension along a run.
  • Interior lining fabric and color that does not match what that model used in that year.
  • A smell of strong glue or chemical finish. Fine leather goods do not smell like that.
  • Hardware engraving that is cast into the shape rather than cut cleanly.
  • Dust bags and boxes are the easiest thing in the world to counterfeit. They prove nothing on their own.
  • A price that is well under the going rate. It is the oldest signal there is and it is still the most accurate.

Certificates of authenticity from third-party sellers are worth close to nothing. They are printed by whoever is selling the bag. A genuine bag does not come with one.

Common questions
My Louis Vuitton has no date code. Is it fake?

Not necessarily. Louis Vuitton stopped using date codes in 2021 and moved to an embedded microchip instead. On a bag made since then, no date code is exactly what you should expect. On an older bag it is a genuine concern.

Can a serial number prove a bag is real?

No. Serial numbers and date codes are copied freely, and a valid-looking number on its own proves nothing. It is useful as a cross-check against the hardware, the style and the claimed year, not as a verdict by itself.

What is the single most reliable check?

On Hermes it is the hand saddle stitching, which is very hard to reproduce. On Chanel and Louis Vuitton there is no single tell any more, which is why it has to be several things agreeing at once.

Will you tell me if a bag I already own is authentic?

Yes, free and with no obligation, whether or not you want to sell it. Bring it to the store and we will tell you what it is.
