What it means: The issuer says the transaction was processed in the wrong currency, or the currency / dynamic currency conversion was not properly disclosed.
Mastercard has consolidated many older codes into 4808, 4834, 4837, 4853, 4863, 4870 and 4871; this legacy code may still appear on older or region-specific disputes.
How to respond: Show the currency charged is the one the customer agreed to at checkout, and any currency conversion was disclosed and accepted.
Stripe usually labels this dispute as: general (check the reason shown on your dispute — Stripe maps network codes to its own categories).
DisputeDesk provides general information and document preparation help. It is not legal advice, and we do not guarantee any dispute outcome — the card issuer decides. Reason-code names and rules change; always check the dispute details in your Stripe or Shopify dashboard and the card network's current rules.
