The CVC2 number on your debit card is a crucial security feature that helps prevent unauthorized transactions. It's a three-digit code located on the back of your card, and it's used to verify your identity when making online or phone purchases.
The CVC2 number is also known as the Card Verification Value 2, and it's a specific type of security code designed for debit cards. You'll never find the CVC2 number on your debit card statement or online account information, so keep it safe and secure.
To make a purchase online or over the phone, you'll be asked to provide your debit card number, expiration date, and CVC2 number. This helps the merchant verify that the card is legitimate and that you're the authorized cardholder.

What It Stands For
CVV stands for Card Verification Value. It's a unique number that provides an extra layer of security for online transactions.
The CVV is a three- or four-digit code, depending on the type of card. For Visa, Mastercard, and Discover cards, it's always three digits, while American Express cards have a four-digit code.
This code is encoded or printed on the physical card, and it changes every time you make a purchase with a virtual payment card or digital wallet.

Preventing Fraud with Codes
Card Verification Data (CVD) codes are a crucial part of preventing fraud, especially during online transactions. They're the three or four-digit codes on the back of your payment card that help authenticate you.

The CVV is stored in the magnetic stripe on the back of the card or in the chip of a chip-and-pin card, making it harder for fraudsters to get their hands on it. Merchants are not allowed to store CVV codes in any way if they want to be PCI compliant.
The response codes from the authorization process can help determine the next action - approval, exception, or decline. Here's a breakdown of the possible response codes:
Non-compliance with global PCI DSS standards can result in a hefty fine or even the cancellation of merchant facilities by the payment processor.
Card Verification and Support
The CVV2/CVC2/CVD/CID codes on your debit card are used to further authenticate you during online transactions.
These codes are usually three or four digits and are found on the back of your card.
For Visa, the response message for a match is "M".
MasterCard's response message for a match is also "M".

Discover's response message for a match is "M" as well.
American Express' response message for a match is "Y".
If the response code is "N", it means there's no match. This applies to Visa, MasterCard, Discover, and American Express.
If the response code is "P", it means the code hasn't been processed. This is also applicable to Visa, MasterCard, and Discover.
If you're unsure about the response codes or have questions, you can call the technical support number provided with your processing equipment or software.
Card Details and PIN
Your debit card has a Card Verification Value 2 (CVV2) number, a 3-digit code found on the signature panel at the back of the card. This number is used to verify card-not-present transactions.
The CVV2 number is not the same as your Personal Identification Number (PIN), which is a 4-6 digit code you enter to authorize a transaction at an ATM or point-of-sale terminal. You should never share your PIN with anyone.
