Amazon Transparency is an anti-counterfeit serialization program launched in 2017 that assigns every unit of an enrolled ASIN a unique alphanumeric code (the “T-code”). Amazon scans that code on the way out of the fulfillment center, and any unit missing a valid Transparency code is blocked from being shipped. Once a brand enrolls a UPC, no seller — authorized or otherwise — can move that item through Amazon’s network without the codes.
Why It Matters for Sellers
Counterfeit units erode reviews, trigger buyer complaints, and often show up as hijacker offers on the Buy Box. Transparency shifts protection upstream: instead of chasing bad actors after the fact, the program stops unserialized units from entering the pipeline in the first place. For brands losing units to gray-market resellers, this is one of the few Amazon-owned mechanisms that materially reduces counterfeit exposure across every marketplace where the ASIN sells.
How Transparency Works
- Brand enrolls in Amazon Brand Registry, then applies to Transparency through the Brand Registry dashboard.
- Amazon generates a batch of unique T-codes; the brand prints one on each unit (or its packaging) during manufacturing.
- Codes are scanned at Amazon fulfillment centers before shipment to the buyer.
- Any FBA or FBM unit without a valid code is quarantined and returned to sender.
- Buyers can scan the code with the Amazon Shopping or Transparency app to verify authenticity.
