Discover Card - Code UA31

Definition: What this fraud dispute means is that during the course of a card not present transaction, an acquirer or a merchant obtained an invalid proof of delivery. Card not present transactions are typically either transactions which are completed over the internet, or transactions which are completed by mail or by telephone.

Explanation: Proof of Delivery was Invalid.

How to prevent this Chargeback: In order to prevent this type of dispute from escalating into a chargeback, you must be able to show a valid proof of delivery for the card not present transaction in question.

How to resolve this Chargeback: If this fraud dispute escalates into a chargeback request, the best way to dispute the chargeback or to resolve it is to provide supportive documentation which shows that the proof of delivery in question is not invalid, or instead to obtain a proof of delivery which is valid in order to settle the disputed card sale or transaction.

Tips: Providing a valid proof of delivery is generally enough to make this chargeback go away. If you have not delivered the products or services that were purchased, providing them as soon as possible is the only way to resolve the card holder dispute. If the proof of delivery that you provided was fraudulent or invalid, you can solve this dispute by providing valid details in lieu of the invalid ones.
