Le Pliage is light, simple and sold nearly everywhere, which makes it easy to copy and easy to miss in photos. A Longchamp authentication focuses on the small parts: the leather flap with its embossed horse and rider, the snap, the zipper, the stitching and the interior tag. Le Pliage nylon and leather, Roseau bags and wallets all get a real or fake verdict with a certificate.

What we check on Longchamp

How to tell a real Longchamp from a fake

No single detail settles a Le Pliage, so we start with whether the label inside agrees with the bag in your hands. Our authenticators then compare the leather, hardware, nylon and finishing with verified Longchamp references.

01

Inside label and reference

The reference on the label names a model, a line and a color, and all three have to match the bag. Label layout and print have to fit the line.

02

Leather flap and horse emboss

The blind-embossed horse and jockey above the snap, the leather grain and how the flap is stitched to the body.

03

Snap button

The horse motif and LONGCHAMP 1948 lettering on the snap face, and the stamp on its underside.

04

Zip pull

The engraved ring with the horse and jockey, LONGCHAMP and 1948, and its finish for the model.

05

Leather-bound edges

The stamped LONGCHAMP line on the handle covers and edges, and even stitching where the handles meet the body.

06

Nylon or leather

Weave, weight and color of the nylon, or the cut, grain and edge finish on leather models.

07

Shape and fold

Proportions for the model and size, and how the bag folds and sits.

Read your Longchamp Reference

The reference is printed on the transparent label sewn inside a Longchamp bag: the model number, then three characters for the line and three for the color. Every bag of that model shares it and it carries no date, so it cannot prove a bag is real. Our experts can.

Featured questions

Have more questions? Visit our Help Center

Is there a Longchamp serial number or verification code checker?

Longchamp bags carry a reference number, not a serial. Every bag of the same model, line and color shares it, and it holds no date. Our free Longchamp reference number check reads what each part names, and Longchamp offers no public lookup. A well-formed reference does not prove the bag is real.

Where is the reference number on a Longchamp bag?

On the transparent label sewn inside the bag, usually the last line of text above the care symbols. Longchamp's own product pages print the same code as the Reference. Photograph the whole label in sharp focus and include it with your photos of the bag.

Can a fake Longchamp have a correct reference number?

Yes. Counterfeits copy references from real bags and listings, so a code can check out on a fake. What counts is agreement: the model, line and color the reference names should match the bag, and the bag itself has to pass on its leather, hardware and finishing.

My Longchamp says Made in China. Is it fake?

Not because of that line. Longchamp says it makes bags in its own workshops in France, Tunisia and Mauritius and with partner workshops in France, China, Romania, Portugal, Vietnam and Morocco, and the label shows the country of assembly. We judge the bag, not the country.

Can you check a Le Pliage on Vinted or eBay before I pay?

Yes. Ask the seller for photos of the front, the flap and snap, the zip pull, the handles, the inside label and the inside of the bag, then upload them. Longchamp says any purchase outside its own site and its official or approved retailers is at the buyer's own risk, so checking first is worth it.

Does a Longchamp authenticity card or receipt prove the bag is real?

No. Authenticity cards, receipts and dust bags are easy to print or reuse with a different bag, so they are supporting evidence at most. Send photos of the bag and its label and the verdict rests on the bag itself.

Which photos should I upload for authentication?

For the most accurate and quick authentication process, we advise you to upload clear photos of the areas visible when clicking 'Upload photos' on this page. We quickly determine if the uploaded photo meets our criteria. If your photos do not meet the criteria, you will receive a request for more and/or clearer photos. Check out Photo Instructions to find clear examples for each detail.

How long does LegitGrails authentication process take?

We provide a range of authentication response times to suit your needs, with options including 12 hours, 6 hours, 2 hours, and 30 minutes.
