Applicability

This Specification Bulletin applies to:

• EMV Integrated Circuit Card Specifications for Payment Systems, version 4.3, November 2011, Books 1 through 4

Description

ISO published a new version of the ISO/IEC 7812-1 standard in 2017 where the Issuer Identification Number (IIN) is expanded to an 8-digit numeric value from the current 6-digits. Some payment systems are moving to an 8-digit Bank Identification Number (BIN), the BIN being the equivalent of the IIN, whereas other payment systems are continuing to use a 6-digit BIN. The current EMV ICC Specification defines the Issuer Identification Number (IIN, tag '42') data object as a fixed length 6-digit numeric value. To support longer Issuer Identification Numbers of 8-digits, and to ensure that terminals already using the existing fixed length 6-digit IIN (tag '42') are not adversely impacted, this Specification Bulletin adds the new data object Issuer Identification Number Extended (IINE, tag '9F0C') as a variable length data object with a length of 6 or 8-digits.

While the first 6-digits of the IINE (tag '9F0C') and IIN (tag '42') are the same and there is no need to have both data objects on the card, cards may have both the IIN and IINE data objects present. n 6 or 8 'BF0C' or '73' '9F0C' var. 3 or 4 In Annex B2, Table 50: Data Element Tags, add the following new entry in the appropriate tag order: Issuer Identification Number Extended (IINE) 'BF0C' or '73' '9F0C' Changes to EMV ICC Book 3 In Section 7.5 Erroneous or Missing Data in the ICC, after the fifth paragraph in the bulleted list, add the following new bullets in the appropriate alpha order:

In Section 10.2 Read Application Data, Footnote 9, update the first sentence as shown below: Payment system-specific tags are interpreted within the context of the application RID. Issuer-specific tags are interpreted within the context of the Issuer Identification Number (as defined in ISO/IEC 7812-1).
