Discover DP: Duplicate Processing
What the cardholder is claiming
The cardholder says the same transaction hit their card twice: one purchase, two charges.
The evidence that actually wins
Bank analysts skim responses in minutes against a checklist for this exact code. Lead with the strongest fact; never make them dig.
- ✓Records showing the two charges are distinct transactions: separate order numbers, different items, and different timestamps
- ✓Separate authorization approval codes for each charge, proving each was independently authorized
- ✓Two separate receipts or order confirmations, each independently acknowledged by the customer
- ✓Proof one of the charges was already refunded or reversed before the dispute
The honest read
If it is a true duplicate, refund the second charge the moment you find it, ideally before it becomes a chargeback that adds fees to a loss you were always going to take. The bank can see both authorizations, so denying an actual duplicate just burns your credibility on future disputes. The winnable version is two legitimate charges that happen to look alike: same amount, same day, a customer who really did order twice. Distinct order IDs and separate confirmations settle that quickly.
Nobody can promise you a win; the cardholder's bank decides. What you control is submitting the strongest complete case your records support, on time. Our plain-language guarantees say exactly what that means.
