Where do I find my Credit Card Security Code?

This is a three- or four-digit number that is printed after your sixteen-digit credit card number, on the back of your credit card. Take a look at the front of your card. You’ll see a sixteen digit number embossed on it. Now look at the back of your card. That same sixteen digit number will be printed there, along with an extra three or four digits at the end. That’s your security code.

Some cards have only the last four digits of your card printed on the back, together with your three-digit security code. Check your card number against the printed digits: the ones that are not part of your card number are your security code.
