Some questions ?

Which Louis Vuitton accessories do we authenticate?


Our R&D service of authentication photo analysis of second-hand products from the Louis Vuitton brand concerns all the brand's bags and suitcases as well as scarves, squares, belts, Louis Vuitton shoes, small leather goods, Louis Vuitton purses and Louis Vuitton fashion jewellery.

What do I need to check the authenticity of my Louis Vuitton bag purchased on Vinted, leboncoin, cloakroom collective, Facebook?


If you have the accessory in question, all you have to do is take 6 quality photos showing the details, finishes, seams, signatures in an obvious way (from all angles) and submit them to ourconformity checker.

If you do not have yet the Louis Vuitton item (you are about to buy), please submit the ads to us. We will then analyze them using the same principle (artificial intelligence combined with human analysis).

I want to buy a used Louis Vuitton bag, how can I check its conformity?


By using our imaging and artificial intelligence laboratory approved by the Ministry of Research and Innovation, we are able to verify the conformity of the Louis Vuitton bag you wish to acquire by analyzing the seller's ad.

We make a complete analysis of the ad, the text, the state, the conformity through the shots of the article according to the photos present and/or absent but also with the relevance of the description written by the advertiser. Finally, we send you a prior notice to allow you to position yourself and negotiate with the seller with full safety in advance

Once purchased, upon receipt of your package, you will send us your own photos to check if they match with that of the ad and confirm the conformity of your purchase. Thus, you will then get a certificate of conformity or, if applicable, of non-compliance, in order to be able to return your purchase or be reimbursed by PayPal.

How to be sure to buy an Authentic Louis Vuitton bag?


To be sure of the authenticity of a Louis Vuitton item, it is recommended to go to the Louis Vuitton website or to one of their stores to make your purchases.

Buying without being accompanied on a site or a second-hand shop involves a significant risk

Our compliance analysis service is adapted to this situation. It aims to prevent you from having bad experiences with counterfeits. In particular, it will demonstrate your intention not to want to buy a counterfeit and your respect for your favorite brand.

How do I authenticate a used or second-hand Louis Vuitton bag myself?


Even if you are presented with an invoice or a certificate from the house, we advise you to check with an independent third party, to use our services for example. Indeed, being able to issue a notice of compliance requires the expertise that we have developed in our laboratory, in particular thanks to artificial intelligence, but also via our analysts who have several decades of experience in the field of Louis Vuitton bag authentication, and other brands.
