!!! Overview[1]
[{$pagename}] is a numbering system for an International [Identification] system for various industries defined in [ISO 7812]

!! [Bank Card Number]
[{$pagename}] ([IIN]) is the first 6 digits of your [Bank Card Number] (including the initial [Major Industry Identifier] digit).

We also see [{$pagename}] described as ''__Bank Identification Number (BIN)__''.

Some of the better known issuer identifiers are listed in the following table:

!! [Integrated Circuit Card IDentifier|Integrated Circuit Card Identifier]
[{$pagename}] is used in the [Integrated Circuit Card IDentifier|Integrated Circuit Card Identifier]

!! [National Council for Prescription Drug Programs|http://www.ncpdp.org/|target='_blank']
[{$pagename}]s are also used on [National Council for Prescription Drug Programs|http://www.ncpdp.org/|target='_blank'] pharmacy claims to identify processors, and are printed on all pharmacy insurance cards. IINs are the primary routing mechanism for real-time claims.

!! [{$pagename}] is NOT[1] 
The [{$pagename}] differs from the Bank Identifier Code ([BIC]/[ISO 9362], a normalized code—also known as [Business Identifier Code], [Bank International Code], and [SWIFT code]). It also differs from [Universal Payment Identification Code], another identifier for a bank account in the [United States].
