9F25
Last 4 Digits of PANLast 4 Digits of PAN exists for exactly the situations where showing the full PAN (5A, referenced alongside it, already covered in this dictionary) would be excessive or risky, but showing nothing at all would leave a cardholder or merchant unable to confirm which card was actually used - a receipt, a transaction-history entry, or a dispute-resolution screen typically only needs enough of the PAN to distinguish it from a cardholder's other cards, not the whole number. Because it's derived directly from 5A, a mismatch between what 9F25 shows and the last four digits actually embedded in 5A is a data-integrity red flag worth resolving immediately, in the same category as the 5A-versus-57 and 5A-versus-9F6B cross-checks already covered elsewhere in this dictionary - all variations on the same principle that the same PAN fact, expressed in more than one field, should never be found disagreeing with itself. See EMV 4.4 Book 3.
