CC# to Bank?

[iago]

Does anybody know where I can find information about how to determine which bank a credit card number is from? For example, "4510xxxx" is Vista.

I'm going to research this myself, but I thought somebody could save me time if they've seen this before (particular those who've written online apps).

<edit> I love Wikipedia! http://en.wikipedia.org/wiki/Credit_card_number

I eventually found a program that could look them up one by one: http://www.mars-soft.net/banksbase.htm

It has a bunch of .dat files which appear to be a proprietary database format. I studied the files and wrote a primitive parser in C. It worked perfectly and I managed to extract them. Life's good!
