This format consists in numbers, letters, dash and underline.

When using the Alias 2.0 format we additionally return the parameter fingerprint from our APIs. It's a unique identifier for the underlying card.

It helps you for example to identify customers who signed up with the same card number.

This format consists of the first 6 digits of the real credit card number, the actual BIN Range (Bank Identification Number), followed by the token in form of 6 upper-case letters.
The Masked Credit Card Token ends with the last 4 digits of the actual credit card number.
Based on card brand the length of the token varies.
