# Standard BIN Mapping
{% hint style="info" %}
A **BIN** is a ***Bank Identification Number*** or ***Issuer Identification Number,*** which is the first six digits of a card number. These digits can be used to identify the Type of Card: each Card Type has a designated range of BINs.
{% endhint %}
BIN mapping allows you to make sure certain Card Types are directed to certain gateways.
A typical example of BIN mapping would be to map all AMEX Cards to the gateway you have that will process AMEX.
