Viewing First 6 digits of credit card

[WhiteWolf]

Hello,
I am using FirstData/Linkpoint/YourPay API
and I am using ZenCart 1.3.9d

When I am in the admin screen, and go to Customers -> Orders, and the credit card is shown as follows:
4111XXXXXXXX5555

i.e. I can see the first 4 digits. This was fine, but after a few cases of fraud, I would like, in some cases, to call the bank issuing the credit card for further investigation.

So, my question is how to view the first 6 digits instead of the first 5?

THanks

You can login to your Linkpoint/FirstData console and view the entire details there.
The details are NOT stored within Zen Cart.
