The credit card verification code is the 3-digit number on the back of the card, which is also a security code.

Credit card verification code, abbreviated in English as CVC (full name CardVerificationCode), is an additional code printed on the back of the credit card. It is also called CVV (CardVerificationValue), which is the credit card verification value, and some are also called CID, which is the credit card security code or Personal Security Code, etc., all names refer to the same verification code. Please note that this verification code does not refer to the credit card password. (Generally speaking, only credit cards issued domestically may have a password, while credit cards issued overseas do not have a password.) The display location is on the back of the credit card, with the top end of the signature in italics. The first four digits are the card number, and the last three digits are the verification code.

Warm Tips

One of the ways to use credit cards is called "payment without card", or "payment without card and password". You only need to provide the card number and the three digits on the back of the credit card. The verification code (CVV, also known as the "last three codes") can complete the payment. In addition, people’s awareness of the confidentiality of CVV ??codes is quite weak, giving criminals an opportunity to take advantage of them. Therefore, no matter how tightly protected credit cards and passwords are, they may still be stolen.
