What is a CVV Number?

When it comes to making online purchases, security is a top priority for both consumers and retailers. 

What is CVV Number?

One important aspect of online payment security is the CVV number. In this article, we will take a closer look at what a CVV number is, why it is important, and how to use it safely.

What is a CVV Number?

The CVV (Card Verification Value) number is a three or four-digit code printed on the back or front of a credit or debit card. It is used as an additional security feature for online or phone transactions where the card is not present. The CVV number helps to verify that the cardholder is the one making the purchase, as it is not typically included on the magnetic stripe or chip of the card.

The Four-Digit CVV: Which Card Has It?

One such card is the American Express or Amex card. Unlike Visa, Mastercard, and Discover, which all have a three-digit CVV, Amex cards have a four-digit code printed on the front of the card, above the card number.

This four-digit CVV is also known as a Card Identification Number (CID) or Card Validation Code (CVC), and it serves the same purpose as a CVV. It helps to ensure that the person making the transaction has the physical card in their possession and is authorized to use it.

While the use of a four-digit CVV may provide an extra layer of security, it's still important to protect your card information by following the Dos and Don'ts of using your card. Be sure to keep your card and CVV number secure, only use trusted websites and retailers for online transactions, and regularly monitor your account activity for any unauthorized transactions.

Why is CVV Number Important?

The CVV number provides an additional layer of security for online transactions, helping to reduce the risk of fraudulent purchases. Without the CVV number, someone who has stolen your credit card information could use it to make purchases online. However, since the CVV number is not typically stored on the magnetic stripe or chip, it cannot be easily copied by skimming devices or other fraudulent means.

In addition to providing an extra layer of security for online purchases, the CVV number can also be used as a tool for merchants to identify and prevent fraudulent activity. By requiring customers to enter the CVV number during checkout, merchants can verify that the card is in the possession of the customer and reduce the risk of chargebacks or disputes.

How to Use CVV Number Safely?

To ensure that your CVV number is used safely, it is important to keep your credit or debit card information secure. This means avoiding sharing your card details with anyone else, including family members or friends, and being cautious when entering your card information online or over the phone.

When entering your CVV number, make sure to only enter it on secure websites with SSL encryption. Look for the padlock icon in the address bar and ensure that the website URL starts with "https" rather than "http." If you receive a suspicious email or phone call requesting your CVV number, do not provide it and contact your bank or card issuer immediately.

Dos for Protecting CVV:

  • Sign the back of your card and keep the receipt from the bank.
  • Memorize the three-digit CVV number on the back of your card and erase it from any written notes or documents.
  • Memorize your card PIN and don't write it down anywhere.
  • When swiping your card, make sure merchants swipe it on a Point of Sale (POS) terminal in your presence. Shield the POS PIN pad while entering your PIN.
  • Change your PINs regularly.
  • Register for SMS and email alerts to monitor your account activity.
  • Verify transactions in your bank statement regularly to identify any suspicious activity.


Don'ts for Protecting CVV:

  • Do not share your credit/debit card numbers or CVV number with anyone, even bank officials.
  • Do not share your One Time Password (OTP) with anyone over the phone or by mail.
  • Do not carry out financial transactions while using public networks, such as Internet cafes or free Wi-Fi.
  • Avoid using ATMs located in isolated or dimly lit places without security.
  • Do not crumple and throw away ATM transaction slips. Destroy them into small pieces and dispose of them safely.
  • Beware of unsolicited calls, texts, or emails asking for sensitive financial information like debit card/credit card/ATM pin/CVV/expiry date or password.
  • Do not delay reporting a lost debit/credit card to avoid the worst consequences.


The Bottom Line

A CVV number is a three- or four-digit code printed on the back or front of your credit or debit card, used for online transactions to verify that the card is in the possession of the buyer. It's important to protect your CVV number by not sharing it with anyone, memorizing it, and destroying any written records of it. By taking necessary precautions and following the Dos and Don'ts, you can protect your financial information and make secure online transactions.
