Decline code 15: No Such Issuer
The first digits of the card number do not map to any issuing bank. The network could not route the authorization because the BIN does not exist in its routing tables. Unlike code 14, where the issuer rejects the account, here there is no issuer to ask.
Should you retry?
There is nothing to retry; no issuer exists for this number and no delay changes that. Only a corrected card number, submitted fresh, can succeed. This is a Category 1 code under Visa reattempt rules.
Why code 15 happens
- The customer mistyped one of the first six to eight digits, producing a BIN that no bank owns.
- A fraudster generated card numbers with fabricated BIN ranges that fail routing.
- An extremely new or reassigned BIN range has not propagated, which is rare but occurs during industry BIN expansions.
- Test card numbers from a sandbox environment leaked into production traffic.
What to do about it
- Have the customer re-enter the card number, paying attention to the first digits where the routing information lives.
- Implement BIN validation at checkout against a current BIN database to catch impossible prefixes before authorization.
- Check that production traffic is not carrying sandbox test PANs after a deployment or environment change.
- Treat repeated 15 responses from a session as enumeration activity and rate-limit accordingly.
Frequently asked questions
- What does no such issuer mean?
- The card number's opening digits do not correspond to any bank in the card network's routing system. It is almost always a typo in the first digits or a fabricated card number, since real cards always carry a routable BIN.
- Is decline code 15 the same as invalid card number?
- They are related but distinct. Code 14 means the issuer exists but does not recognize the account. Code 15 means the network could not even identify an issuer to route to. Both are permanent for that number as entered.
