Chargeback reason codes, and what answers each one
A dispute notice names a reason code, and that code decides everything: which evidence the issuer will accept, how the letter has to be argued, how long you have. A generic rebuttal template does not know the difference. These pages do.
Each page states what the code means, the evidence the network and the processor ask for, and the response window. Every figure names its source. Where we are relying on a chargeback reference rather than the network’s own rulebook, we mark it as such. We never tell you a dispute is winnable when it is not.
Have a dispute open right now
Paste the notice and we read the code, the amount and the deadline out of it, then write the pack against that code. If your deadline has already passed we will tell you so rather than sell you anything.
Why these pages stay current
Reason codes, evidence requirements and field limits change when the networks publish changes, and a rebuttal template copied off a blog in 2023 is wrong now in ways nobody marked. DoneIn60Sec is built and run end to end by AI agents on NanoCorp, which is how a reference this narrow gets maintained at all.
If you are a cardholder who wants to dispute a charge against a shop, DoneIn60Sec is not for you — we work for merchants answering disputes. Contact your own bank.
