How we authenticate designer bags step by step
AUTHENTICATION PROCESS

At Vintasje, authenticity is one of the most important steps of everything we do. Over the years, we’ve become experts in sourcing and authenticating designer bags, and we take that responsibility very seriously.

Carefully sourced

Most of our designer pieces are sourced through trusted and certified resellers we’ve built long-term relationships with over the years. This allows us to source with confidence from the very beginning.

Expert in-house inspection

Before any item goes online, we carefully inspect it ourselves. With years of experience in designer authentication, we check every detail: from stitching and materials to hardware, date codes and stamps.

Get our digital Certificate of Authenticity

With every order, you'll receive a digital Certificate of Authenticity directly in your inbox. This certificate confirms that your item has been carefully inspected and verified by our in-house experts, guaranteeing 100% authenticity.

Extra verification with Entrupy

For selected items, we use Entrupy as an additional authentication step. Entrupy is a system that uses a handheld microscopic scanner to capture highly magnified images of materials, logos, and stitching. When available, the official Entrupy certificate can be bought with the item.

WHAT TO LOOK FOR WHEN AUTHENTICATING A DESIGNER BAG

Stitching

Luxury bags are crafted with precise and consistent stitching. Uneven lines, loose threads or irregular spacing can be a red flag.

Hardware

Authentic designer hardware feels heavy, high-quality and well-finished most of the time. We always check engravings, zippers, logo details and metal quality carefully.

Stamps & logos

Brand stamps and logos should be clean, sharp and perfectly aligned. The font, spacing and placement are often key authentication details.

Date codes & serial numbers

Many designer brands use date codes, serial numbers or authenticity stickers. We verify whether these details match the brand, production year and model.

Materials & craftsmanship

Authentic designer bags are made from premium materials with exceptional craftsmanship. The feel, structure and finish of the leather or canvas often say a lot.

Overall details

When authenticating a bag, it’s never just one detail; it’s the full picture. Years of experience help us recognize whether a piece truly meets designer brand standards.
