At Vierlot, authentication is not a formality — it is the foundation of everything we do. Every single item listed on our platform passes through a strict, standardized multi-layer verification process before it is ever offered for sale.

Dual In-House Expert Review

Each piece is independently inspected by two senior authenticators. We examine materials, craftsmanship, hardware, stitching, brand markings and serial numbers — and we never rely on a single person’s judgment.

Technology-Backed Verification

We partner officially with LegitApp and Entrupy. LegitApp combines AI analysis with professional authenticators and issues a digital certificate for every item, while Entrupy’s patented microscopic testing is available for eligible handbags on request.

What Comes With Your Order

Every order ships with a physical QR security tag and an official digital authentication certificate, so you can verify your item online at any time. For full details, see our Authentication & Authenticity Guarantee.
