5F56
Issuer Country Code (alpha3)Issuer Country Code (alpha3) completes the trio of country-code encodings already covered in this dictionary alongside the numeric form (5F28) and the two-letter form (5F55, referenced alongside it here): the same country fact expressed as a three-letter ISO 3166 code, for whatever systems or display contexts specifically expect that particular format over the other two. With all three forms now documented, the practical guidance is the same one already given for 5F55: a terminal or analysis tool encountering more than one of these fields on the same card should treat disagreement between them as a genuine data-integrity concern worth investigating rather than picking whichever one happens to be present and ignoring the others, since all three are meant to state the identical fact about the issuing country, just formatted for different conventional uses. See EMV 4.4 Book 3.
