When you're buying something online or by phone, you'll often be asked for your credit card's CVV number, sometimes also called the card security code. CVV is short for card verification value, and it's a key security feature.
What is a credit card CVV?
The CVV is a three- or four-digit code that's printed on your credit card as a fraud-prevention measure. When you provide this number for an online or phone purchase, the merchant will submit the CVV when it authorizes the transaction. It's an attempt to verify that you have the physical card in your possession and that you're not just using stolen card information.
Stop fraud in its tracks
With a NerdWallet account, you can see all of your credit card activity in one place and easily access your credit report to spot any red flags quickly.
Visa, MasterCard and Discover cards have a three-digit CVV printed on the back of the card, usually next to the signature panel. Sometimes, you’ll also see the last four digits of your card’s account number listed along with the three-digit CVV; those four numbers appear before your CVV and don’t count as your CVV, so don't enter them when prompted online for your CVV.
American Express cards have a four-digit CVV located on the front of the card, just above and to the right of your account number.
For all four card networks, the CVV is printed on the card, rather than embossed in raised lettering.
The value of CVV numbers lies in how your credit card information is stored by merchants.
Merchants that handle credit card transactions are allowed to store your card data (with your permission) so you don't have to type it in again every time you buy something from the site. However, if your card information is stored, it has the potential to be stolen in one of the data breaches that have become common.
The CVV adds another layer of protection. Security standards in the payment industry prohibit merchants from storing CVV numbers. That way, even if a database is compromised, hackers still won’t have the CVV and won’t be able to use the stolen card numbers anywhere that requires the code.
This leads to the question of why sites that handle recurring payments — such as retailers like Amazon or subscription services like Netflix — can process payments on a stored credit card without you re-entering your CVV every time. These sites typically ask you for your CVV when you first use a card. From them on, they treat that card as valid for your account. But if your data is stolen, the CVV won't be included with it, so it will be of limited use elsewhere.
As you’ve probably noticed, not all merchants require you to enter a CVV. Transactions can be authorized without it. A crook who has your card number and expiration date could use the information at such merchants.
Plus, there’s always phishing. A scammer may ask you for your credit number as well as your CVV, or might obtain your credit card account number and use that information to lure you into giving your CVV. Be sure to keep your personal data and account numbers safe from phishers, and learn to recognize the most common scams.
Where is the CVV or security code on a card? On Visa® and Mastercard® credit cards the CVV is located on the back of your card, next to the signature box.
How do I find my CVV number online? You can find the CVV number on the back of your debit or credit card. In case you want to see your CVV number online, you can check your virtual debit card, available on the mobile banking app or your net banking portal.
The CVV is a 3 or 4 digit code embossed or imprinted on the reverse side of many credit or debit cards. This is an extra security measure to ensure that you have physical possession of the credit card itself.
How Are CVVs Generated? As it turns out, CVVs are not random three- or four-digit numbers. Rather, banks generate them using four pieces of information: primary account number, four-digit expiration date, a pair of DES (Data Encryption Standard) keys and a three-digit service code.
Most card issuers use a three-digit code on credit and debit cards, including VISA, Mastercard, and Discover. But American Express uses a four-digit CVV. Each CVV is unique to the card and account holder, meaning there's no universal CVV code.
Is it safe to give out a CVV number? When shopping online, it's generally safe to use your credit card security code. Most online retailers require CVV details for purchases, which is encouraging because it means that they're trying to prevent fraudulent transactions on their site.
You can call your bank, or the institution that issued you your card, tell them you lost your card and you need a replacement. Unfortunately, if the CVV code has faded, you will not be able to retrieve it. You will need to contact your card issuer for a new card with a new CVV code.
Start by logging into your online banking portal or mobile app. You can use these platforms to access your Credit Card details. If you've made online purchases recently, your browser's autofill feature might have your Credit Card information saved.
CVV stands for Card Verification Value. It is a three or four-digit number, usually printed on the physical Debit and Credit Cards. There are two CVVs: the first is encoded in the magnetic strip, while the other is visible on the card. For online purchases, the latter is used.
One way to do this is to simply call up your credit card issuer and ask them for your CVV number. They will be able to look up your account information and give you the number. This is probably the easiest way to get your CVV number if you don't have your card with you.
For Visa®, Mastercard® and Discover® cards, the CVV is a three-digit number, and it usually appears on the back of the card, typically next to the signature box. American Express cards have four-digit CVV numbers, and they appear on the front of the card.
CVV2/CVC2/CID is a security feature for transactions where your credit card is not physically present. It is a three or four digit value which provides our payment system with a check of your credit card's authenticity. The terms are generally used interchangeably.
Where can you find CVV on your Debit Card? If you use a VISA or MasterCard, you will find that the CVV printed contains a three-digit code and is located on the back of the card, near the signature area.
It's important to note that CVV numbers are not a requirement for processing an online credit card purchase. It is up to the retailer whether to ask this question as part of the transaction process as an added measure of security.
