When you make an online purchase using your credit or debit card, the card number and the expiration date are not the only information you are asked for. The vendor will also require your CVV number to process your transaction. What is CVV, how to find it, why it is so important, and more – read on to find out.
What Is CVV Number?
CVV stands for Card Verification Value. CVV is a 3 or 4 number that is printed on the card which provides a security feature to verify that the person using the credit or debit card during a transaction is the actual card owner. It adds a security layer to protect a person’s sensitive data during online transactions.
How Is CVV Generated?
CVV number is not a random number. It is generated using a complex algorithm that involves the card issuer’s unique key, the card number, and the card’s expiration date. The CVV code is not stored on the magnetic stripe or chip of the card, which makes it difficult for hackers to obtain it.
Components of a CVV Number
A CVV number on a debit card has two main parts:
- Magnetic Strip: This strip is located on the back of your card and holds important information about your account. When you swipe your card at a payment machine, the magnetic strip is read, and it shares unique data that helps identify your card. Because this information is specific to your card, it’s crucial to keep it private and not share it with others.
- Three-Digit Code: Alongside the magnetic strip, there’s a three-digit code visible on the back of the card. You’ll need this code for online transactions to help verify your identity. However, when you make purchases in person, you don’t have to enter the CVV, as the payment machine reads the necessary data automatically.
Different Issuer Acronyms
While CVV is the common term used in the industry, different card issuers have their own names for the security code found on debit and credit cards. Here’s a breakdown of what this code is called by various issuers:
- CVV2: This stands for Card Verification Value 2 and is used by Visa.
- CVC2: This also means Card Verification Value 2 and is the term Mastercard uses.
- CID: This stands for Card Identification Number, which is what American Express calls it.
- CVV: This simply refers to Card Verification Value and is used by RuPay.
Understanding these acronyms can help you navigate card security more easily.
What’s the Difference Between a CVV and a CVV2?
CVV and CVV2 are both security codes found on credit and debit cards, but they differ in how they are created. The "2" in CVV2 indicates that this code is generated using a newer, more secure method, making it tougher to guess. Despite this difference in security, both CVV and CVV2 serve the same purpose. They help protect your card from fraud by verifying that the person using the card has it in hand during online or phone transactions.
Where Can I Find the CVV Number on my Card?
For Visa, Mastercard, and RuPay cards, you can find the CVV number on the back of the card. It’s usually the last three digits on the signature strip or just to the side of it. If you have an American Express card, the security code is on the front, above your account number, typically on the right side.
What Is the Purpose of CVV?
All credit card and debit card providers have created a system where every card generated has a unique CVV code. This code is generally required when you are making online or virtual transactions using your card. The purpose of the CVV is to establish the owner’s identity and help safeguard the credit and debit card against theft, fraud, or unauthorized transactions.
Difference between CVV and PIN
| PIN | CVV |
| User-created personal identification number | Automatically generated and printed on the back of the card by the credit card issuers |
| Mostly a 4-digit number | 3-digit code |
| For credit cards, PIN is used for cash advances and for debit cards, PIN is used for cash withdrawals from ATM and point of sale (POS)s | Used for online transactions or for virtual payment gateways |
How Does CVV Protect You From Identity Theft?
Debit and credit cards are generally used for virtual payment gateways or online transactions. It is against the law for these portals to save the CVV number of the cardholder. This means that even if the vendors have your card details, they cannot access your CVV. Since the CVV is not stored in the databases, in situations where your card information is compromised, the fraudster cannot use your card because they cannot access the CVV. Hence, CVV acts as a security layer and protects your card against identity theft and other fraudulent activities.
DOs & DON’Ts While Using CVV Number
DOs
- Keep your CVV safe and never share it with anyone.
- Only enter your CVV on secure websites.
- Check your bank statements regularly for any fraudulent activity.
- Contact your card issuer immediately if you suspect any fraudulent activity.
DON’Ts
- Don’t write down your CVV or store it in an easily accessible location.
- Don’t share your CVV with anyone, especially if the person requesting it is not authorized to do so.
- Don’t enter your CVV on unsecured websites.
Why Do Online Stores Ask For Your CVV Instead Of Your PIN when Checking Out?
Online stores ask for your CVV instead of your PIN when checking out because CVV is a security feature that verifies the card’s authenticity, whereas a PIN is used to authorize transactions at a point of sale (POS) terminal. Since online transactions do not involve a POS terminal, CVV is used as an additional layer of security to ensure that the person using the card is the actual card owner.
How Can You Protect Your CVV?
To protect your CVV, never share it with anyone, especially if the person requesting it is not authorized to do so. Also, avoid writing it down or storing it in an easily accessible location. Only enter your CVV on secure websites, and if you suspect any fraudulent activity, contact your card issuer immediately.
All credit cards and debit cards have CVVs to prevent fraudulent purchases made online or on the phone. CVV is harder to access than your other card information, but it doesn’t always guarantee protection. They help prevent fraud, but they are not foolproof. Therefore, you must always take necessary precautions to protect yourself while transacting online or on your phone.
