Transaction refusal codes constitute a standardized classification system designed to communicate the precise reason for payment authorization failures within the electronic payment processing infrastructure. This reference documentation establishes a comprehensive framework for interpreting declined transactions across multiple failure scenarios.

Decline Codes

The table below describes each Decline Code in more detail.
Refusal Reason CodeRefusal ReasonDescription
0(none)Sometimes refusalReasonCode: 0 is returned along with resultCode: Authorised. When this happens, ignore the refusal reason code. The transaction succeeded.
2RefusedThe transaction was refused.
3ReferralReferrals.
4Acquirer ErrorThe transaction did not go through due to an error that occurred on the acquirer’s end.
5Blocked CardThe card used for the transaction is blocked, therefore unusable.
6Expired CardThe card used for the transaction has expired, therefore unusable.
7Invalid AmountAn amount mismatch occurred during the transaction process.
8Invalid Card NumberThe specified card number is incorrect or invalid.
9Issuer UnavailableIt is not possible to contact the consumer’s bank to authorise the transaction.
10Not supportedThe shopper’s bank does not support or allow this type of transaction.
113D Not Authenticated3D Secure authentication was not executed, or it did not execute successfully.

14Acquirer FraudPossible fraud.
15CancelledThe transaction was cancelled.
16Shopper CancelledThe consumer cancelled the transaction before it was completed.
17Invalid PinThe specified PIN is incorrect or invalid.
18Pin tries exceededThe consumer entered an incorrect PIN more than three times consecutively.
19Pin validation not possibleIt is not possible to validate the specified PIN number.
20FRAUDThe pre-authorisation risk checks resulted in a fraud score of 100 or more. Therefore, the transaction was flagged as fraudulent and was refused.
21Not SubmittedThe transaction was not submitted correctly for processing.
22FRAUD-CANCELLEDThe sum of pre-authorisation and post-authorisation risk checks resulted in a fraud score of 100 or more. Therefore, the transaction was flagged as fraudulent and was refused.
23Transaction Not PermittedThe following declined codes are mapped to this refusal reason:
  • 57: Transaction not permitted to issuer/cardholder
  • 57: Transaction not allowed for this merchant
  • 58: Transaction not permitted to acquirer/terminal
24CVC DeclinedThe specified CVC (card security code) is invalid.
25Restricted CardThe following decline codes are mapped to this refusal reason: “62: Restricted Card” “62: Invalid card in this country”
26Revocation Of AuthIndicates that the consumer requested to stop a subscription. Decline codes such as the following are mapped to this refusal reason: “R1: Revocation of Authorization Order” “R3: Revocation of All Authorizations Order” “R0: Stop Payment Order”
27Declined Non GenericThis response maps all those response codes that cannot be reliably mapped. This makes it easier to tell generic declines (for example, Mastercard “05: Do not honor” response) from more specific ones.
28Withdrawal amount exceededThe transaction amount was higher than the withdrawal amount permitted for the consumer’s card.
29Withdrawal count exceededThe consumerexceeded the number of withdrawals that is permitted for the consumer’s card.
31Issuer Suspected FraudIssuer reported the transaction as suspected fraud.

37Contactless fallbackThe consumer abandoned the transaction after attempting a contactless payment and being prompted to try a different card entry method (PIN or swipe).
38Authentication requiredThe issuer declined the authentication exemption request and requires authentication for the transaction. Retry with 3D Secure.
39RReq not received from DSThe issuer or the scheme wasn’t able to communicate the outcome via RReq.
40Current AID is in Penalty BoxThe payment network is currently unavailable. Retry the transaction with a different payment method.
41CVM Required Restart PaymentA PIN or signature is required. Retry the transaction.
