Discover Reason Code AA: Does Not Recognize
The Discover cardmember does not recognize the transaction on their statement — a recognition dispute that often resolves once the merchant and purchase are identified.
Your strongest argument
Order, authentication, and delivery records identify the purchase and tie it to the genuine cardmember.
Evidence that wins a Discover AA dispute
- A clear billing descriptor and the merchant name shown to the cardmember
- Order details, AVS/CID results, and device/IP tied to the cardmember
- Delivery confirmation or proof of product use
