Visa reason code 12.3
Visa 12.3: Incorrect Currency
What the cardholder is claiming
The cardholder says the transaction was processed in a different currency than disclosed, or that dynamic currency conversion was applied without them actively choosing it.
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.
- ✓The receipt or checkout screen showing the transaction currency and exact amount the cardholder saw and accepted
- ✓DCC opt-in proof: a signed receipt or logged checkout step where the cardholder actively chose conversion over the local currency
- ✓Terminal or gateway configuration records showing local currency was the default and DCC required an explicit choice
- ✓Settlement records showing the cleared currency and amount match what was disclosed at the point of sale
The honest read
Dynamic currency conversion is the whole game here, and the burden sits on you to prove the cardholder made an active, informed choice to convert. Terminals configured to default into DCC generate disputes you will keep losing, because the rules are written assuming the merchant benefits from the conversion spread. If your receipt shows a clear currency choice, present it; if DCC was applied silently, credit the difference and reconfigure the terminal.
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.
