Reason Code AA – Does Not Recognize

The maximum amount of time that can pass between the transaction processing date and the chargeback processing date is 120 calendar days.

However, the timeline may be extended if the issuer first submitted a retrieval request. If the retrieval request process finishes after the 120 day deadline, the issuer will have an additional 30 days to file a chargeback.

Examples of compelling evidence that you may submit in response to a chargeback with this reason code include:

• Proof the cardholder agreed to the transaction
• Proof the cardholder received a cash advance or cash back at checkout
• Proof the cardholder received the goods or services that were purchased
• An imprint of the card or proof a PIN was used at checkout
• Proof that the chargeback is invalid because it doesn’t adhere to Discover’s requirements
• Proof you have already refunded the transaction and credited the cardholder’s account

• Always respond to retrieval requests on time and with the required information.
• Consider using all the identity verification tools available to you—such as the card security code (CID) and Address Verification Service (AVS).
• Use pre-sale fraud detection service providers that can help verify the cardholder’s identity, detect potential criminal activity, and reduce the risk of accepting unauthorized transaction.
• Use a billing descriptor that is easily recognized by the cardholder.
