We know of no public Lacoste serial number lookup, and QR codes on some products can be copied, so a real or fake answer has to come from the item. For Lacoste polos, bags and sneakers, an authenticator checks the crocodile, buttons, petit piqué fabric, labels and stitching. On a classic polo, the separately embroidered crocodile patch and mother-of-pearl buttons trip up cheap copies.

What we check on Lacoste
How to tell a real Lacoste from a fake
The crocodile is the first thing we check on a Lacoste polo: its embroidery, the jaw, teeth, claws and tail. The buttons, the petit piqué and the labels then have to agree with the model.
01
Crocodile
Embroidery density and edges, the shape of the jaw, teeth, claws and tail, and how it is sewn on the chest.
02
Placket and buttons
On the classic polo, mother-of-pearl buttons, their sheen and how they are sewn on.
03
Petit piqué fabric
The fine honeycomb knit of the classic polo, its weight and the collar ribbing.
04
Size label
Sizing, fonts and stitching of the neck label.
05
Care and wash tags
Tag text, country of manufacture and production codes for the season.
06
Stitching
Hem, side vents and collar construction.
Bags and leather goods
01
Crocodile and logo
Shape and finish of the crocodile and the Lacoste lettering on the bag.
02
Interior label
Font, stitching and any codes or QR label inside.
03
Hardware
Zips, pulls and engravings.

We know of no public serial number lookup from Lacoste. Its own brand protection page says it cannot authenticate items bought outside its official network, and its online check is for websites, not products. Some Lacoste products carry a QR code, but codes can be copied, so it is one checkpoint, never proof.
Look at the crocodile first: dense embroidery with clear teeth, claws and tail. Then check the mother-of-pearl buttons on the placket, the honeycomb petit piqué fabric, the size label and the care tags. Upload photos of each and a professional authenticator checks them against verified Lacoste references.
No. A QR code links a tag to a product page, and a copied tag can carry a copied code. Not every Lacoste item has one either. We treat the code as one checkpoint and decide on the crocodile, the buttons, the fabric and the labels.
Yes. Send photos of the logo, the interior label, the hardware and the material for a bag, or the side profile, insole, size tag and outsole for sneakers.
Yes. Ask the seller for photos of the crocodile up close, the buttons, the size label and every care tag, then upload them before you pay. You get a verdict, Authentic or Fake, from a professional authenticator.
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.
We provide a range of authentication response times to suit your needs, with options including 12 hours, 6 hours, 2 hours, and 30 minutes.
