CVC control number (Card Verification Value/Code)
The CVC control number is a three-digit number, typically the last three digits in a row and they are printed on the back of all VISA, Eurocard, MasterCards and Diners cards (not American Express).
You can find your four-digit card verification number on the front of your American Express credit card above the credit card number on either the right or the left side of your credit card.
