What Discover Reason Code 4752 Means
Discover reason code 4752 identifies a dispute in which the cardholder does not recognize a transaction on their statement and questions whether they authorized it.
Why This Chargeback Happens
This dispute commonly occurs when a billing descriptor is unclear, when a purchase was made by a family member, or when the cardholder simply does not recall a legitimate transaction. It can also reflect genuine unauthorized use.
What the Cardholder or Issuer Is Claiming
The cardholder claims they do not recognize the transaction and cannot confirm that they authorized it.
What Merchants Should Review
Review the billing descriptor, order and customer details, authentication and verification results, delivery or usage records, and any prior undisputed purchases from the same account.
Recommended Chargeback Evidence
- A clear, recognizable billing descriptor tied to the sale
- Order details linking the transaction to the cardholder
- AVS, CVV, or authentication results from the authorization
- Delivery confirmation or evidence of service usage
- Records of prior undisputed purchases from the same account
How to Prevent Similar Disputes
Does-not-recognize disputes may be reduced by using clear billing descriptors, sending purchase confirmations, and responding promptly to cardholder inquiries and dispute alerts before a chargeback is filed.
