What is a CVV code and where can I locate it on my credit card?

The CVV number (Card Verification Value) on your credit or debit card is a 3 digit number on Visa and MasterCard branded credit and debit cards. 

*If you are using an American Express branded credit or debit card you will instead use the 4 digit numeric code. CVV numbers are NOT your card’s PIN (Personal Identification Number).
