Question

What is Credit Card Number?

Answer 1

There are two numbers on a credit card, the front of the card has your account number and the on the backside, usually adjacent to the signature line you will see three numbers. Those three numbers are called by different names but I believe the most common is "C C V which stands for Customer Card Verification. Those three number are requested from merchants when placing phone or on line purchases. It implies that you have the card in your possession.
