What Discover Decline Code P6 Means
Discover decline code P6 (New PIN Not Accepted) indicates that a new PIN was not accepted by the issuer.
Where the Response May Come From
Code P6 means a newly selected PIN was not accepted, often because it did not meet the issuer's PIN requirements. It concerns a PIN-selection operation, so the issuer's rules govern the outcome.
Common Reasons for This Response
Common causes include a new PIN that does not meet issuer requirements.
Should the Merchant Retry the Payment?
Reattempting with a non-conforming PIN repeats code P6; the customer typically needs to choose a compliant PIN, often through their issuing bank.
Recommended Merchant Action
Advise the customer to select a new PIN that meets their bank's requirements, completing the change with the issuing bank where necessary.
What to Tell the Customer
Ask the customer to choose a new PIN that meets their bank's rules, or to contact their issuing bank for help.
How to Reduce Similar Payment Failures
Recognizing responses like code P6 helps you guide customers to set a compliant PIN with their bank instead of retrying a rejected one.
Important Limitations
Decline-code meanings vary by processor, gateway, and payment environment, and issuers do not always disclose the specific reason behind a response. The retry classification on this page is Payment Defender editorial guidance, not an official network rule. Merchants should confirm handling with their processor or gateway.
