Credit card cvv2 code is usually printed on the card face, and different credit cards have different printing positions. The cvv2 code of most credit cards in China is printed on the right side of the signature on the back of the credit card and consists of three digits.

however, foreign credit cards, such as cvv2 code of American Express Card, are usually printed under the card number on the front of the credit card and consist of 4 digits. Credit card cvv2 code is very important. In normal times, it is necessary to ensure its safety and avoid leakage. It is best to stick it with opaque thin tape.

Extended information:

1. The CVV2 code in the credit card is a number printed in the signature area of the Visa/Master Card card card. It is located in the 3 digits after the credit card number. The last three digits we usually see on the back of a credit card are actually CVV2, not CVV code. In addition, cvv2 code, also known as credit card security code, is a security code for credit card transactions, which is equivalent to the credit card ID card.

Second, the cvv2 code is equivalent to the ID card of a credit card, and we can use the cvv2 code for consumer transactions. The cvv2 code is very convenient for our consumption. Shopping on overseas websites does not require a password. As long as the buyer provides the account number and security code, the transaction can be completed. At home, there are also merchants who sign contracts with banks, but they can complete the telephone transfer without a credit card password and only with the security code.

3. The card number, expiration date and CVV2 code are directly printed on the credit card. Once someone records these information and knows the cardholder's mobile phone number at the same time, even if they can't get the credit card, they can steal the credit card on Ctrip. Therefore, cvv2 code is convenient for our consumption, and it also shows its importance, so we must protect it.

Fourth, the cvv2 code in the credit card is very important. I suggest you cut a small piece of tape and stick the CVV2 code to prevent leakage. At the same time, you should also fully protect your credit card, try your best to ensure that the card does not leave your body, do not let the credit card leave your sight when spending, and do not give the card to the clerk to check out, so as to avoid the card information being viewed by outsiders.
