Visa reason code 12.6
Visa 12.6: Duplicate Processing / Paid by Other Means
What the cardholder is claiming
The cardholder says either the same purchase was charged twice (12.6.1, Duplicate Processing) or that they paid for it another way, in cash or on a different card, and were charged on their Visa card anyway (12.6.2, Paid by Other Means).
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.
- ✓Two distinct invoices, order numbers, or receipts proving the supposedly duplicate charges were separate purchases
- ✓Itemized records and delivery or service confirmations mapping each charge to its own goods or services
- ✓Settlement records showing only one capture exists for the transaction in question
- ✓For paid-by-other-means: your payment records for the order showing no cash, check, or second-card payment was ever received
- ✓The credit reference if one of the two charges was already refunded
The honest read
Check your own batch before writing a word, because retried settlements and POS glitches produce genuine duplicates more often than merchants expect, and a real duplicate should be credited immediately, not defended. The winnable version is two legitimate charges that merely look similar: same customer, same amount, same day. That fight is won with invoice numbers, timestamps, and itemization that make the two purchases unmistakably distinct.
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.
