An cvv2 is a carding-slang for credit card information, used by carders. This info includes credit card number, expiry date and the actual CVV2 code.

The CVV2 itself means "creditcard verification value 2", which are the last three digits on the back of every creditcard (sometimes four digits, f.e. American Express). These three digits are primary used for online purchases, combined with the credit card number and expiry date.
