INSIDE OUR AUTHENTICATION PROCESS

Luxury Begins With Trust. Discover the careful authentication process behind every item in our collection.

When purchasing luxury online, authenticity is everything.

At Vintage-United, authentication is not simply one step in our process—it is the foundation of everything we do.

Since 2015, we have specialised in carefully sourcing and curating authentic luxury designer fashion. Every item is individually examined before it is added into our collection because our reputation depends on every single piece we sell.

Our goal is simple: to ensure every client can purchase with complete confidence.

Our Philosophy

Luxury is built on craftsmanship, heritage and exceptional attention to detail.

The same principles guide our authentication process.

Rather than relying on a single method, we combine years of specialist experience with advanced authentication technology and independent verification whenever required.

Every item is evaluated individually because no two luxury pieces are exactly alike.

Step 1 — Personal Authentication

Every item begins with a detailed manual inspection performed by our authentication specialist. Years of experience handling authentic luxury brands allow us to recognize the subtle characteristics that distinguish genuine craftsmanship from counterfeits.

Depending on the brand and category, we carefully examine numerous authenticity indicators, including:

• Leather quality and natural grain
• Hardware finish, engravings and weight
• Brand logos and heat stamps
• Stitching quality and construction
• Serial numbers, date codes and production details
• Zippers, closures and interior finishing
• Overall proportions and craftsmanship
• Materials and finishing techniques
• The characteristic scent of genuine luxury leather

Every detail contributes to the overall authentication assessment.

Step 2 — Entrupy Authentication

Whenever applicable, designer handbags undergo an additional independent authentication using Entrupy technology.

Entrupy combines artificial intelligence with microscopic imaging technology to analyse leather at a microscopic level. This advanced technology compares millions of data points against an extensive database of authentic luxury handbags.

This provides an additional layer of verification alongside our own specialist expertise.

Step 3 — Documentation Review

Whenever available, we carefully examine all accompanying documentation, including:

• Original purchase receipts
• Serial magnetic plates
• Serial cards
• Date codes
• Brand documentation
• Original packaging

Although original documentation alone never guarantees authenticity, it forms an important part of our overall authentication process.

Step 4 — Independent Verification

If additional verification is required, we obtain an independent second authentication through LegitGrails.

We believe confidence should never be based on assumptions.

When additional expertise adds value, we seek it.

Our philosophy is simple:

We would rather decline an authentic item than ever risk offering a counterfeit.

Authentication Across Every Category

Proof of Authenticity

Every authenticated designer handbag purchased from Vintage-United is delivered with proof of authenticity.

Our clients can shop knowing that every handbag has undergone a careful authentication process before being offered for sale.

Why Our Process Matters

The luxury resale market continues to grow, making professional authentication more important than ever.

Buying authentic luxury should never rely on hope or guesswork.

It should be based on expertise, careful inspection and complete transparency.

At Vintage-United, authentication is not simply a service we provide.

It is the standard we hold ourselves to every single day.

Our Commitment

Every item that becomes part of the Vintage-United collection has earned its place through careful inspection, independent verification where applicable, and years of specialist expertise.

We don’t simply sell luxury. We help our clients buy luxury with complete confidence.
