What is an Issuer Identification Number (IIN)?
The Issuer Identification Number (IIN) is the first six digits of the account number on your plastic card. In the case of a National IIN that starts with "9826", the IIN is the first eight digits i.e. "9826xxxx" with digits 5-8 being assigned by APACS. The whole number is known as the Primary Account Number (PAN) and has a maximum length of 19 digits.
