What is a CVV Number?
When you make purchases online, you typically need to enter your credit card details, which include a card verification value (CVV) number. This CVV number is a key security feature that helps prevent credit card fraud, such as identity theft. You can usually find this code on the back of your card near the signature box, though it’s placed on the front for American Express cards.
The CVV is essential for enhancing the security of your online transactions. It acts as a verification tool that online merchants use to confirm that the purchaser has the card physically present, as the CVV isn’t stored in the card’s magnetic stripe or on any transaction receipts, making it challenging for thieves to acquire. For secure online payments, always use websites with HTTPS encryption for entering your CVV and avoid sharing it via email or on insecure platforms. Additionally, keeping an eye on your bank statements and setting up alerts for unusual activities can help safeguard against fraudulent charges.

What Is a CVV?
CVV stands for “Card Verification Value” and is a security feature found on most credit and debit cards. It is a three—or four-digit security code printed on credit and debit cards. The code is used as an added security measure for card-not-present transactions, such as online or telephone-based payments. CVV is not used for card-present transactions. Since its introduction, CVV has helped greatly reduce online, phone, and mail-order credit card fraud incidents.
The CVV (Card Verification Value) is a crucial security feature on credit and debit cards. It is a three or four-digit code printed on the cards and is used as an additional security measure for card-not-present transactions, such as online or telephone-based payments. This extra layer of security helps verify that the person making the transaction physically possesses the card. In card-present transactions, the CVV is not required. Since its introduction, the CVV has significantly reduced online, phone, and mail-order credit card fraud, offering consumers and businesses added peace of mind when conducting non-face-to-face transactions.
How Does the CVV Code Work?
Card security codes act as two-factor authentication, utilizing two pieces of information – such as your credit card number and the CVV – to verify your identity as the cardholder. The CVV confirms that you physically have the card, which helps to prevent fraudulent activities. If an incorrect code is entered, the transaction will be declined.
The CVV functions similarly to a seatbelt for your credit card. It is one of several security measures that, when combined, provide enhanced protection for your credit card.
Despite rules that prevent merchants from saving your CVV data, online transactions can still be processed without it. For example, many subscription services require the CVV only during the initial sign-up. Subsequent charges may be approved without needing to re-enter the CVV.

The History of CVV Security Codes
The History of CVV Security Codes
CVVs, also known as Card Verification Values, Card Verification Codes, Card Security Codes, or Card Identification Numbers, vary in name depending on the card issuer. They were introduced in the late 1990s and early 2000s as a response to the growing trend of online shopping. With the increased popularity of online purchases, there was a corresponding rise in online credit card fraud, prompting the need for enhanced security measures to protect consumers. The concept for CVV originated in the UK and was developed by Michael Stone, who worked at Equifax then.
At first, the CVV was an 11-digit number, but it was eventually streamlined to a more manageable 3- or 4-digit code. MasterCard® pioneered the implementation of CVVs on credit and debit cards in 1997, and American Express® followed suit in 1999. Visa® joined the trend in 2001, making CVVs a standard security feature across major card networks.
Where Is a Credit Card CVV Located?
The card security codes for MasterCard®, Visa®, Discover®, and JCB® are usually located on the back of the card, to the right of the signature space, and are a group of 3 numeric digits. The American Express® CVV is a group of 4 numeric digits printed on the card’s front face above and to the right of the card number.
However, the security code might be located in a different spot on some cards, such as on the back, beneath the credit card number. If you can’t find the CVV number or if it’s worn and difficult to read, you should contact the card issuer.
If your card isn’t on hand and you need the CVV number, you might not be able to retrieve it immediately. However, your credit card company might allow you to view this information through its mobile app.

What are The Different Terms for Card Security Codes?
Each card company has their own preferred name for their version of a card security code. Below are a list of card security code names, what each stands for, and which card brands use them.
- “CVV2” – Card Verification Value 2 – Visa®
- “CVC” – Card Verification Code – MasterCard®
- “CVC2” – Card Validation Code 2 – MasterCard®
- “CVD” – Card Verification Data – Discover®
- “CID” – Card Identification Number – Discover® and American Express®
- “CVN2” – Card Validation Number 2 – China Union Pay®
- “CSC” – Card Security Code – American Express®
What’s the Difference Between a CVV and a CVV2?
The CVV and CVV2 codes are security features used in credit and debit card transactions. While both codes serve the same purpose of enhancing transaction security, they differ in their generation methods and level of security.
The CVV is generated using a specific algorithm, whereas the CVV2 code utilizes a more advanced encoding technique, making it more secure than its predecessor. Although cardholders may not notice the difference between the two codes visually, the underlying security enhancements are significant.
Whether you are entering a CVV or CVV2 during online purchases, the experience remains consistent, with a primary focus on safeguarding your financial data. Both codes are crucial in preventing unauthorized use of your card for online or over-the-phone transactions.
What’s the Difference Between a CVV and a CVV2?
Why Is CVV2 Used Instead of CVV1?
Why Is CVV2 Used Instead of CVV1?
Technically, one or the other is used in a transaction. The CVV1 is a code embedded in the second track of the credit or debit card’s magnetic strip. The CVV1 is read by the credit card machine or swiper during swipe transactions. The CVV2 is used when the card cannot be swiped, such as in phone or online orders. Since the CVV1 cannot be read, the cardholders are asked to supply the CVV2 number in such situations.
What Are the Security Benefits of Card Security Codes?
Per the ‘Payment Card Industry Data Security Standard (aka PCI DSS) regulations, CVV2 data must not be held in any payment system database after a transaction is complete. This is a cornerstone to why CVV security works. Because CVV information cannot be stored, if the database is comprised the card data stored within is less useful to fraudsters. This not only protects the cardholder from online hackers but also protects the cardholder from fraudulent merchants or employees.
The other main security benefit is the obvious one; In card-not-present transactions, requiring the CVV helps verify that the physical card is in the customer’s possession.
Is a CVV the Same as the Card PIN?
No, a CVV is different from a card PIN. PIN stands for “Personal Identification Number” and is the secret passcode the cardholder sets for their debit cards. During a “card-present” transaction, the PIN is required as a security measure to ensure the customer is the owner of the card. On the other hand, the CVV is a 3-4 digit security code printed on the back of the card and is used as added security in “card not present” transactions.
The Future Of Card Security Codes – Dynamic CVV
The development of dynamic CVV code is a groundbreaking advancement in credit and debit card security. This innovative system seeks to replace the traditional static CVV code by integrating a small screen on the card that dynamically changes the security number every 30 to 60 minutes throughout the card’s lifespan, typically 3 to 4 years.
The proposed screen technology closely resembles popular e-readers, necessitating minimal energy to update the displayed numbers while consuming no energy to maintain the display. This forward-looking technology is projected to have shallow energy demands. It is anticipated to be widely adopted within the next few years, although specific implementation timelines have yet to be finalized.

Is CVV Truly Secure?
The CVV system provides an enhanced layer of security for credit card processing transactions. Since CVV isn’t allowed to be stored, per data security and PCI DSS compliance, it is less likely to be part of online data breaches. However, that doesn’t mean that CVV codes can’t be intercepted, stolen, and misused online. It is imperative to protect your data and to never input your CVV code on websites you aren’t sure you can trust.
Treat your CVV number as secure data and protect it with the same level of security you would apply to account numbers and other personal information. If your CVV security code were to become compromised, it may make the transaction seem more legitimate to an unsuspecting merchant.
What about American Express CVV Codes?
American Express is different but also has CVV codes for additional security. Instead of a 3 digit CVV on the back of the card, Amex has a 4 digit CVV value on the front of the card just above the account number on the right. CVV is an important security measure for American Express cards, and users should protect the 4 digit Amex CVV code the same way they would protect a 3 digit CVV code on Visa, MasterCard, or Discover.
Can People Easily Guess CVV Numbers?
When you’re checking out online, you have undoubtedly been prompted to enter the Card Verification Value, or CVV number, as an additional security measure. If you didn’t have the number available, you might have tried to guess it, or you might have tried to remember your CVV number. If you didn’t remember correctly, you undoubtedly saw a decline code from the merchant. Since a CVV value is only 3 digits (or 4 digits for an American Express CVV), you might think that it is easy to guess.
However, submitting multiple transactions with different CVV codes will undoubtedly set off security alarms with your card issuer and the merchant. Three digits might not seem like iron-clad security for a PIN, but they effectively deter fraud in e-commerce transactions. The four-digit American Express CVV is even more difficult to guess and provides even better security. Per PCI DSS standards, processors can’t allow unlimited guesses for CVV values.
What about American Express CVV Codes?
Why Is CVV2 Used Instead of CVV1?
Can Merchants Store CVV Codes?
Merchants are prohibited from storing the CVV value in any way. The 3-digit CVV for Visa, MasterCard, and Discover, as well as the 4-digit CVV for American Express, must never be stored in any point of sale, terminal, software, or e-commerce system. Merchants must strictly adhere to the prohibition of storing the CVV value for Visa, MasterCard, Discover, and American Express cards. The 3-digit CVV for Visa, MasterCard, and Discover and the 4-digit CVV for American Express must not be retained in any system, including point-of-sale terminals, software, or e-commerce platforms.
Regarding recurring payments, merchants can use the CVV to first authorize when a credit card is added to the digital wallet. However, the CVV code is no longer required for subsequent transactions on recurring billing. Notably, the absence of the CVV for future billings will not lead to interchange downgrades or declines.
How Can I Safeguard My CVV Codes?
Taking prudent security measures can help safeguard the CVV codes from your credit and debit cards. To help keep your data secure, you should only shop online and enter your CVV with trusted retailers. If you have doubts, see if that merchant offers third-party payment acceptance, such as AmazonPay or PayPal.
Only shop at e-commerce stores that protect your CVV data with encryption and HTTPS. Be alert for invalid SSL certificates or warnings that might put your CVV data at risk. When paying at a physical store, keeping the card in your sight is best. Restaurants are one of the prime places where card data and CVV values are stolen. If you can pay at the table on a mobile terminal or through an app on your phone, that can help safeguard your CVV code. If you are concerned that your CVV value might be at risk, it is best to seek out an ATM to pay cash or to ask for alternative payment options.
Maintaining the security of your credit card number and CVV is crucial, and there are multiple other steps as well you can take to safeguard your information:
- Utilize a password manager: Many password managers are available for free and help you generate and manage unique, strong passwords for different sites.
- Avoid storing personal information on retailer sites: Although convenient, saving your details on websites increases the risk of theft. It’s safer to manually enter your card information with each online purchase.
- Be cautious with email links: Be vigilant about emails that look authentic but ask you to provide your credit card details through a link. Only give such information to known and reliable banks or retailers, and verify their official contact details.
- Monitor your accounts regularly: Check your credit card statements for unauthorized transactions and review your credit report periodically. If your card goes missing or is stolen, contact the issuer immediately using the contact number provided on the back of your card or on your statement.
- Avoid sharing card photos: Do not share or store photos of your card that might be automatically uploaded to cloud services like iCloud or Google Photos, as they could be accessed during data breaches.
How Can I Safeguard My CVV Codes?
- Use a VPN on public networks: Always activate a VPN when connecting to Wi-Fi outside your home to encrypt your personal information and protect against unauthorized access.
- Install antivirus software: Equip your devices with antivirus software to defend against viruses, keystroke loggers, and other malicious tools that can compromise your personal data.
