Authentication Service
GENDA's professional authentication service verifies that high-value items are 100% authentic before they reach buyers.
Trust & Transparency
At GENDA, we're committed to creating the most trusted marketplace for authenticated products. Our rigorous authentication process ensures that every high-value item sold on our platform is verified by experts before reaching the buyer.
Unlike other marketplaces that only authenticate certain brands or randomly sample items, we authenticate every eligible item over $300 in select categories, giving both buyers and sellers complete peace of mind.
Our authentication team includes experts from auction houses, brand specialists, and industry professionals who know exactly what to look for.

How Authentication Works
1. List Your Item
Create a detailed listing with photos. Eligible items will display an 'Authentication Available' badge.
2. Buyer Makes a Purchase
When your item sells, ship it to GENDA's authentication center instead of directly to the buyer.
3. Expert Verification
Our team of experts verifies your item's authenticity, condition, and consistency with the listing.
4. Authentication Complete
Once authenticated, your item receives our verification seal and is shipped to the buyer.
5. Payment Released
After delivery confirmation, payment is released to your account (minus authentication fee).
Important for Sellers
Be accurate and detailed in your listings. Items that don't match their descriptions or are determined to be inauthentic will be returned to you (shipping fees apply) and the sale will be cancelled. Multiple authentication failures may affect your seller status.

Authentication FAQs
Which items require authentication?
Authentication is required for luxury items and high-value collectibles over $300. This includes designer fashion, limited sneakers, trading cards, and premium electronics. You can see if your item requires authentication when listing it.
How much does authentication cost?
Authentication fees start at $15 and vary based on item value and category. Luxury items over $1000 have a fee of $30. The fee is deducted from the seller's earnings when the item sells.
How long does authentication take?
Most items are authenticated within 1-2 business days after arriving at our authentication center. Complex items may take up to 3 business days. This timeline does not include shipping to and from our center.
What happens if an item fails authentication?
If an item fails authentication, the buyer receives a full refund. The seller can choose to have the item returned (for a shipping fee) or donated. Failed authentications are noted on seller accounts and may affect seller status.
Can I opt out of authentication?
Authentication is mandatory for all items in eligible categories priced above $300. This policy protects both buyers and sellers by ensuring that all high-value items are legitimate.
