Is your online shopping experience truly secure? While it may seem like a simple transaction, there’s a hidden layer of protection, we call CVV. CVV codes play a vital role in protecting your financial information and you must know in detail how it works and how you must protect it for your safety. We will discuss everything about CVV code in this blog, keep reading!
What is CVV Code?
A CVV code, also known as a Card Verification Value, is a three-digit number printed on the back of your credit or debit card. It’s located on the signature strip, usually to the right of your card number.
What Does the CVV Code Represent?
The CVV code represents an additional layer of security for online and phone transactions. The CVV code is specific to your card and is not part of your card number, is not stored digitally in the same place as your card number, making it more difficult for hackers to obtain. Plus, the CVV code helps prevent fraudulent transactions where the cardholder isn’t physically present.
Why is CVV Code Important?
- By requiring the CVV code, merchants can verify that the person making the purchase has physical possession of the card to prevent fraudulent transactions where someone may have obtained your card number without the physical card.
- As CVV codes are not stored in the same place as your card number, if someone gains access to your card number, they won’t have the CVV code needed to complete a transaction.
How is CVV Code Generated?
To generate a CVV, card issuers use complex cryptographic algorithms. These algorithms take the card number, expiration date, and a secret key known only to the issuer as input.
The algorithm then processes this information to produce a hash, which is truncated to three digits to form the CVV. This process ensures that each CVV is unique to a specific card and is difficult to predict or replicate, making it a robust security feature for online payments.
What are the Risks If Someone Knows My CVV Code?
If someone knows your CVV code, they could potentially use it to make unauthorized online purchases. This is because the CVV code is a crucial security measure that verifies that the person making the transaction has physical possession of the card. Here are some of the risks associated with someone knowing your CVV code:
Unauthorized Purchases
The most immediate risk is that the person could use your CVV code to make purchases online or over the phone without your knowledge or consent. This could include buying goods or services or even transferring money.
Identity Theft
If someone has your CVV code along with other personal information, such as your name, address, and date of birth, they could use it to open new accounts or commit identity theft.
Financial Loss
Unauthorized purchases could result in significant financial loss, as you may be liable for fraudulent transactions.
Don’t be the Next Victim: CVV Scams Alert
The rising issue of gift card scams, particularly “card draining,” is on the rise.
State lawmakers are taking action to combat this issue by introducing legislation to mandate secure packaging for gift cards, require retailers to post warning signs, and provide employee training.
However, retailers and gift card manufacturers are pushing back against these regulations, arguing they are unnecessary and could harm small businesses.
In another incident, BDO Unibank warned the public about “vishing” scams on November 15, 2024. Vishing is a scam where someone pretends to be from a legitimate source like a bank and calls you to try to get your personal information, such as CVV codes and OTPs. The scammers then use this information to steal your money.
Some organizations are working smart to protect their customers from card scams, such as ANZ Bank New Zealand which launched a new security feature called Dynamic Security Code to protect online shoppers from fraud.
This code, accessible through the ANZ goMoney app, changes every 12 hours and can be used instead of the traditional CVV code on the back of physical cards.
How to Keep Your CVV Code Safe
Your CVV code is your asset, and you must make efforts to keep it safe. Here’s how:
Don’t Share Your CVV Code with Anyone
Never write down your CVV code and never share it with family, friends, and even customer service representatives (unless they are from your bank and you initiated the call).
Be Cautious of Phishing Scams
These are fake emails or websites that try to trick you into giving up your personal information, including your CVV code. Avoid clicking on the links they have.
Use Strong Passwords for Your Online Accounts
Strong and unguessable passwords protect your information in case of a data breach. Plus, keep your devices secure by using antivirus software, firewalls, and other security measures.
Only Shop on Secure Websites and Safe Connections
Look for the https:// in the address bar and a padlock icon and avoid making online purchases on public WiFi networks, as they are not secure.
Use a VPN
A VPN encrypts your connection, making it more difficult for hackers to intercept your information. Try using a premium VPN because free VPNs will not guarantee safety while you connect to them and might sell your information to third parties.
What Can I Immediately Do If My CVV is Accidentally Leaked?
First off, don’t panic! Secondly, you can follow these steps if your CVV code is accidentally leaked:
Contact Your Bank or Credit Card Issuer
Call the customer service hotline immediately to explain the situation and request a new card with a new CVV code. Also, inquire about any potential fraud monitoring services they offer.
Review Your Online Accounts
Check your online banking and credit card accounts for any unusual activity. Look for any unauthorized transactions or suspicious login attempts.
Change Passwords
Change the passwords for all online accounts where you’ve used the compromised card. Use strong, unique passwords for each account.
Enable Two-Factor Authentication (2FA)
If available, enable 2FA for your online banking and other sensitive accounts to add an extra layer of security by requiring a second form of verification.
Monitor Your Credit Report
Consider placing a fraud alert on your credit report to make it harder for someone to open new accounts in your name. You can also request a credit report to review for any suspicious activity.
Be Cautious Online
Be wary of phishing attempts and avoid clicking on suspicious links or downloading attachments from unknown sources. Remember to always use strong, unique passwords for all your online accounts.

What is the Difference Between CVV Code and Dynamic CVV Code?
What’s the difference between a CVV and a CVV2?
CVV and CVV2 are essentially the same thing. They both refer to the 3-digit security code on the back of your credit or debit card. This code is used to verify your identity during online transactions where the physical card isn’t present.
So, while there might be slight variations in terminology or specific implementations, for practical purposes, CVV and CVV2 can be considered interchangeable.
Are CVV and PIN the Same?
No, CVV and PIN are not the same. While both are security measures used to protect your card information, they serve different purposes. CVV (Card Verification Value) is a 3-digit code on the back of your card used for online and phone transactions. It helps verify that the physical card is present, reducing the risk of fraudulent online purchases.
PIN (Personal Identification Number) is a 4-digit code used for in-person transactions, such as ATM withdrawals or point-of-sale purchases. It verifies your identity and authorizes the transaction.
What Else Is CVV Called?
Some issuers have different names for CVV, which you must be aware of:
