Reason Code DP: Duplicate Processing

The merchant processed one transaction two or more times.

• The merchant erroneously charged an identical transaction twice.
• The merchant submitted the transaction batch twice.
• The merchant processed the transaction, but the customer still paid for the service or products by another method.
• There are multiple receipts for one transaction.

• Review all transaction receipts before you make a deposit.
• Send in one batch at a time.
• Credit a duplicate transaction.
• Train your staff on the correct process of dealing with credit transactions and duplicates.
• If the customer opts to pay with a different mode of payment after initiating a card payment, ensure you void the transaction.

The card issuer gets 30 extra days to file a chargeback if they submitted a retrieval request which was completed after the 120 days.
