First, let's talk about what the security code is:
The card security code is a 3-digit numeric value generated during card printing and printed on the card, used for cardholder verification and to reduce fraud risk. This value is called CVV2/CVC2.
So what should we do when our card's security code has worn off?
Because the security code is printed on the card, it can wear off due to heavy use or exposure to external factors. In this case, you should call the bank that issued the card and request a replacement card.
For security reasons, the expiration date and security code of the newly issued card are generated differently from the previous card.
Why can't we obtain the security code from anywhere else?
CVV2 is a value calculated from the card number and expiration date; however, this calculation cannot be performed without the bank's secret key. For this reason, the code cannot be regenerated from the outside, whether it has been forgotten or has worn off.
Some banks can display card details through a virtual card or mobile app. If this feature is not available, the safest option is to replace the card. Sharing your card number and security code over the phone or with third parties is not recommended.
When requesting a new card, don't forget to cancel the old card and update any automatic payment instructions.
