Decline Code Lookup Tool
Use the decline code lookup to decode payment response codes and understand what a failed transaction may mean. Clear decline code interpretation helps teams separate hard declines from recoverable failures.
What is a decline code?
A decline code is a response from the issuer, network, processor, or gateway that explains why a payment was not approved.
Some codes indicate final declines, while others point to temporary conditions, missing information, authentication issues, or retryable processing errors.
The same code can be labeled differently across processors, so teams should read it together with gateway, issuer, and transaction context.
SmartRetry focuses on identifying recoverable failures and rebuilding the transaction with the right timing, routing, and payment data.
How to use the decline code lookup
- 1
Enter the code or message
Search by numeric response code or by a short decline description from your processor.
- 2
Read the likely meaning
Review whether the code points to insufficient funds, suspected fraud, authentication failure, card restrictions, or a technical issue.
- 3
Decide the next action
Use the result to determine whether to retry, request customer action, enrich the transaction, or stop attempting the payment.
Decline response types
| Type | Typical next step |
|---|---|
| Soft decline | Retry later or rebuild the payment with better context. |
| Hard decline | Stop retrying and ask the customer for another payment method. |
| Authentication issue | Review 3DS, exemption, or customer verification flow. |
| Technical error | Retry after confirming gateway, network, or processor status. |
