In the world of pre-owned luxury, authenticity is everything. Whether you're buying a vintage Louis Vuitton Speedy or a nearly-new Gucci wallet, trust is the foundation of the purchase. That’s where Entrupy comes in — a cutting-edge tool powered by artificial intelligence that’s changing how the luxury resale market verifies authenticity.
At HOUSE OF 1880, we use Entrupy for specific items that require added confidence. Here's why this technology matters, and how it protects both the buyer and seller in the high-stakes world of designer fashion.
What Is Entrupy?
Entrupy is a machine learning–based authentication tool used by resale businesses, pawnbrokers, and luxury marketplaces worldwide. The company’s proprietary device takes microscopic images of the item's surface — think stitching, material texture, and logo printing — and compares them to a massive database of verified authentic items.
It’s not a guess — it’s science.
The result? A certificate of authenticity issued in minutes, backed by a financial guarantee from Entrupy.
How Entrupy Works
Here’s a simplified look at how the process unfolds:
-
Microscopic Imaging
A portable Entrupy device captures 200+ images of an item’s key details, including monogram alignment, material grain, hardware engravings, and even wear patterns.
-
AI Analysis
The device uploads these images to the cloud, where Entrupy’s AI compares them against millions of datapoints across known authentic and counterfeit items.
-
Authenticity Result
In under 15 minutes, Entrupy provides an authentication result — often with over 99% accuracy — along with a certificate tied to that item’s unique characteristics.
Why It Matters for Pre-Owned Buyers
In an industry where counterfeits are becoming more sophisticated, confidence is key. Entrupy provides:
- Proof of authenticity for peace of mind
- A digital record linked to each item
- Resale credibility, increasing the item’s future value
For sellers like HOUSE OF 1880, Entrupy gives us an added layer of trust — especially when sourcing newer models or highly faked styles that benefit from biometric-level inspection.
Note: While many of our pieces are authenticated using traditional in-house expertise (especially vintage and rare models), Entrupy is used when needed to validate materials and monogramming of current models or high-demand items. This hybrid approach ensures both human expertise and technological precision.
What Brands Can Entrupy Authenticate?
As of 2025, Entrupy supports authentication for:
- Louis Vuitton
- Chanel
- Hermès
- Gucci
- Fendi
- Balenciaga
- Prada
- Saint Laurent
- And more…
They also now offer Sneaker Authentication and Fine Jewelry Authentication, expanding their reach into even more resale categories.
Counterfeit Rates Are Rising — So Tech Had to Catch Up
The global counterfeit luxury goods market is worth an estimated $450 billion, with more fakes entering the resale market than ever before. Entrupy uses AI trained on real counterfeits to stay ahead of evolving techniques. That means better protection for ethical buyers and resale platforms that value transparency.
What This Means for HOUSE OF 1880 Customers
At HOUSE OF 1880, we only sell authentic, pre-loved designer goods. In addition to our years of hands-on experience handling vintage and modern luxury, we utilize Entrupy when appropriate to ensure our customers are getting exactly what they paid for — no guessing, no risk.
We believe that authenticity should never be a question. And with Entrupy, it doesn’t have to be.
