The Card Security Code is the 3-digit security code
on the back of your credit or debit card. (For AMEX see below.)

  • Visa calls it CVV2, MasterCard calls it CVC2. JCB call it the CAV2:
    CVV Card Security Code 3-digit Visa MasterCard JCB Internet Merchant Accounts 3-Digit Card Security Code

    (In general the value appears in reverse italic at the top of the signature panel or right most in the signature panel on the back of the credit card.)




  • For American Express cards it is called the CID or 4DBC and
    is 4-digits on the front of the AMEX card:
    AMEX 4DBC 4-digit American Express  Internet Merchant Accounts 4-Digit Card Security Code

    The Card Security Code is different from the Verified by Visa, SecureCode, J/Secure or SafeKey
    password which is set by you when you enroll your card online with those 3-D Secure services.
