Card Verification Value
Your CVC number can be located by looking on your credit or debit card, as illustrated in the image.
The CVC Number is a 3 digit number branded on credit and debit cards. On your American Express® branded credit or debit card it is a 4 digit numeric code.
Providing your CVC to an online merchant proves that you actually have the physical credit or debit card - and helps to keep you safe while reducing fraud.
