Every piece at BYEBYE VINTAGE is professionally authenticated before it becomes part of our collection.

Curated globally. Authenticated professionally.

Trust should never be optional.

Our Authentication Process

Expert Inspection

Every bag is carefully examined by professional authenticators before being selected for our collection.

We evaluate construction, materials, stitching, hardware, date codes, serial numbers, craftsmanship and consistency with the original manufacturing period.

Authentication Certificate

BYEBYE VINTAGE collaborates with Cachet Véritable, a professional authentication specialist based in Paris.

Every bag is delivered with an authentication certificate issued by Cachet Véritable.

Additional Entrupy Certificate

For selected brands, an additional Entrupy AI authentication certificate is available upon request.

Entrupy combines microscopic imaging with artificial intelligence and one of the world's largest luxury authentication databases.

Why We Authenticate

At BYEBYE VINTAGE, authentication is not simply a service.

It is part of our responsibility.

Every piece we curate carries the history and the trust of the person who chooses it.

Our role is to protect both.
