I know that.

I thought there might be some extra validation steps.

I find that strange: you don't know what the steps are but you suspect additional steps. My suggestion is that you do some research first and then ask again.

Confused. You are talking about purely mathematical steps, and not any steps dependent on look up tables? So you are looking for the steps besides, call up the server and ask if the credit card number is valid, correct?

What are the steps that you know and what additional steps do you suspect?

The validation steps I know is Luhn's algorithm and the format of brands of each credit card.
