Authenticity Program

Verify Your Items

Authenticate your listings to build buyer trust, sell faster, and earn higher prices. Two paths: upload your own COA or request third-party expert authentication.

Upload Your Certificate of Authenticity

Already have proof of authenticity? Upload it and get a badge instantly β€” free of charge.

Step 1: Upload Your COA

When creating or editing a listing, upload your Certificate of Authenticity as one of the images. Our AI scans it automatically.

Supported: Certificates, receipts, purchase invoices, authentication cards from brands like Rolex, Louis Vuitton, Chanel, etc.

Step 2: AI Scans for Authenticity Markers

Our system analyzes the uploaded images to detect COA documents, brand markers, serial numbers, and holographic stamps.

Confidence score is generated. Items scoring 70%+ get an automatic badge. Lower scores may require third-party verification.

Step 3: Badge Applied Instantly

If a valid COA is detected, a "Seller-Verified" authenticity badge is applied to your listing immediately. No cost, no wait.

Badge appears on search results, listing page, and the buyer's order β€” increasing trust and conversion.
