Adyen code 15 – No Such Issuer
The card issuer does not exist. The shopper should verify the card details or use another payment method.
What does Adyen refusal code 15 mean?
Adyen refusal code 15 No Such Issuer is returned when the card's BIN (the first 6–8 digits) does not match any recognized issuing bank. The card number may be mistyped, invalid, or belong to a BIN that the acquirer network doesn't support.
Is it a soft or hard decline?
Code 15 is a hard decline. Without a valid issuer to route to, the transaction cannot complete regardless of retries.
Common root causes
Mistyped card number at entry
Test-mode or fictitious card number submitted in live processing
BIN belongs to an issuer not supported by the acquirer
Expired or obsolete BIN ranges
Recommended recovery steps
Stop retrying. The number won't route no matter how many times it's attempted.
Ask the customer to re-enter their card — mistypes are the most common cause.
Verify your acquirer's BIN coverage if you see 15 clustered on specific card ranges.
