What is CVV on a credit card? – The CVV (Card Verification Value) is a crucial aspect of improving security when using credit cards. The CVV (also known as CVC) is the three or four-digit number that is normally found on the back of the card. With American Express, for example, it can also be found on the front of the card.

CVC or CVV for more credit card security

How does the CVV work?

When making online purchases, the buyer is usually asked to enter the CVC, the credit card number, and the card’s expiration date. This request is an additional step to verify the purchaser’s identity. The online merchant uses the CVC to verify the authenticity of the transaction.

The CVC serves as an additional layer of security for transactions. Since it is not stored on the card’s magnetic stripe, it significantly helps minimize the risk of fraud, such as copying credit card data (skimming).

It is of great importance to never give the CVC to third parties and to ensure that it is only entered on trusted and secure websites.

What is the difference between CVV and CVC for credit cards?

CVC (Card Verification Code) and CVV (Card Verification Value) fulfill the same function and serve the same security purpose. They differ mainly in the terminology used by different credit card companies.

Visa refers to this security code as CVC, while Mastercard uses the term CVV. Both codes have three digits and are located on the back of the credit card.

What other names exist for the CVV?

In addition to CVC and CVV, there are other designations, such as CVV2, CVC2, and CID (Card Identification Number), which are used by other card providers such as American Express. They all serve the same purpose: improving online transaction security. They differ only in their names and positions on the card.
