Frequently asked questions
What does Discover reason code NC mean?
Discover NC, Not Classified, covers disputes that do not fit any other Discover code, often after the cardholder's attempts to resolve the issue with you failed. Chase's 2014 update says it removed NC from its Discover list, while Solidgate's documentation still lists it, so whether you see it depends on your processor.
Is Discover NC worth fighting?
Our reference rates NC (Not Classified) sometimes winnable, depending on the evidence you have. The evidence that answers it starts with complete order record: items, amount, delivery and communication. The cardholder's bank decides the outcome.
How long does a cardholder have to file a Discover NC chargeback?
Usually 120 days from the transaction date, under the network's issuer time limits for most codes. Your processor gives you far less time to respond, so work from the due date on the case.
