When is cvv required?

So while it might seem like the payment and anti-fraud landscape is getting more and more complicated, it’s for a good reason. Ecommerce sales are expected to reach $632 billion, and accounts of fraudulent activity aren’t slowing down either: card-not-present (CNP) fraud is predicted to grow by 14% in the next four years.

This is why CVV codes exist, essentially. These codes act as a security measure for CNP transactions since online merchants cannot check customers’ signatures.

It’s common practice for merchants to ask for the CVV code to check and see if the buyer is the rightful owner of the credit card, and is arguably the best way to make sure the customer actually has the card in their possession.

If you’ve ever ordered something online and had the little pop-up direct you to those three digits on the back of your card, then you’ve come into contact with CVV.

CVV stands for "card verification value", but it’s also known as CVV2, CVD (card verification data), CVC or CVC2 (card verification code), or CCV (card code verification).

This is due to naming variability across the tech and cardmember associations that developed their own versions of the tech, but they all work effectively the same way.

The three-digit code is located on the back of a credit or debit card, by the signature strip — except for most Amex cards, where it’s on the front, and is actually four digits long.

While skilled fraudsters have their methods to get their hands on the long number and expiry date on customers' cards through devices such as "skimmers" at ATM machines and on payment terminals, they’re out of luck when they try to use this information online without a CVV code.

The CVV is stored either in the magnetic stripe on the back of the card or in the chip of a chip-and-pin card. Merchants are not allowed to store CVV codes in any way if they want to be PCI compliant — helping protect customers from a data breach as well as making it more difficult for fraudsters to get their hands on the CVV code.

Not complying with these global PCI DSS standards could result in a hefty fine or even worse — the cancellation of the merchant facilities by the payment processor.

As well as fighting online fraud, CVV codes also help merchants prevent that dreaded source of lost revenue: the chargeback. Chargebacks take place when a customer requests that the funds from a payment be reversed, and can happen for a number of legitimate and illegitimate reasons such as dissatisfaction with the product or shipping, buyer’s remorse, chargeback fraud, or incorrect deliveries.

While CVV codes can’t stop all types of chargebacks in their tracks, it’s a lot easier to prove that a customer did actually authorize a payment if they entered a CVV code that only they could have entered with their card handy. This is commonly known as "friendly fraud" where a customer makes a purchase and then claims they never did — though it doesn’t sound too friendly to us!

CVV is just one component in the fight against fraud. Online mechanisms such as AVS (address verification service) and card-side fraud triggers such as repeated out-of-country order codes or high-ticket flags also help prevent fraud.

Since CVV codes aren’t required for absolutely all credit or debit card transactions (this is dependent on the credit card association), some online merchants don’t request them at checkout to avoid losing any sales. However, this is very risky business, as CVV numbers are crucial in the online fight against fraud.

At the very least, merchants should require CVV codes the first time a customer makes a payment with them to verify that they are the rightful cardholder. And remember that merchants can be viable for some or all of the damages that result in fraud if the merchant is found negligent, and not requesting a CVV code could be an example of that.

After capturing the CVV code during a transaction (often referred to as "the last three digits on the back of the card"), the merchant sends all the card details (card number, expiration date, cardholder name and address, and the CVV code) to be authorized by the acquiring bank.

The merchant should include a number that indicates whether or not the CVV is being included together with the authorization request.

The bank then sends the request to the relevant credit card association (Visa, MasterCard, American Express, etc.), and the credit card association sends the request to the card issuer. The transaction is then either approved or declined by the card issuer, and the response is sent back the same way it arrived.

A CVV response code is also sent back when the CVV code was included in the original request. If the CVV code did not match, the merchant makes the call on whether or not to go ahead with the transaction.

It should now be a little clearer as to what CVV codes are, and why they are so important within merchant services — helping merchants not only to fight fraud but also reduce chargebacks.

CVV stands for card verification value. It’s a three- or four-digit number found on most debit and credit cards.

There are several other acronyms for this security feature within the industry.

Since chip-enabled card technology has managed to sharply cut back on physical card fraud, criminals have shifted their focus to the digital realm. Creating fake cards has given way to online information theft. Enter the CVV, which banks and credit card issuers use to reduce fraudulent digital transactions.

There are two CVVs associated with most debit or credit cards. The first is encoded in the magnetic strip used for in-person transactions; the second is visible on the card. This is the one you must input when making an online purchase.

While it can be comparatively easy for skilled hackers to gain access to credit card numbers and expiration dates, CVVs are much more difficult to track down. This is largely due to industry regulations. According to PCI (Payment Card Industry) standards, merchants may store your credit card number and expiration date, but they cannot store your CVV. So, while you may not like to enter the number for each online transaction, doing so is what provides that extra layer of security.

Finding your CVV depends on the type of card you have. For Visa, Mastercard and Discover cards, you’ll find the three-digit code on the back, usually inside or just above the signature strip. American Express does things differently, placing a four-digit CVV on the front, above the Amex logo.

A PIN is a user-created “personal identification number.” Most of the time a PIN is four digits, though some banks require longer numbers. Credit cards use PINs for cash advances, while debit cards use them for withdrawing cash or initiating a purchase. Neither of these PINs is the same as a CVV.

CVVs are automatically generated by the credit card issuer and are printed on the card. While a bank may initially provide a PIN when your debit or credit card is issued, it’s only temporary. In most cases you will be required to change it to a number you designate. You have no such control over a CVV.

As a matter of security, generally, no two cards have the same CVV. If you sign up for a new credit card or replace an existing one, you’ll end up with a new code; the same applies if your current card expires and you receive a replacement. Even if your credit card number is exactly the same, you will still have a different CVV.

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. For obvious reasons, the precise algorithms used are unknown.

To avoid becoming a victim of credit card fraud, you should protect your CVV like any other important piece of financial information. Here are seven simple ways to prevent your CVV from falling into the wrong hands.

Banks and merchants stepped up security for in-person transactions with the introduction of chip-based debit and credit cards. This technology enables the internal code to change each time the card is read, a vast improvement on the magnetic strip. Not surprisingly, this has been very effective at reducing fraudulent activity.

But what about CNP (card-not-present) transactions, such as those taking place online or over the phone? Clearly a physical chip will not be helpful; this is why there is a CVV printed on your card. However, the most skilled criminals are sometimes able to access CVVs, even though merchants are prohibited from digitally storing them.

On every transaction you make using your credit or debit card, a unique 3-digit CVV code is required to complete the transaction. Have you ever thought about the importance of the CVV number is? A CVV number is the acronym for Card Verification Value.

In this article we'll share more about the CVV and why a retailer would ask for it during a transaction.

The CVV is typically three or four digits long and printed on either the front or back of the card.

When you're not physically present at the transaction — such as online shopping or over the phone — it's referred to as a card-not-present transaction. People are more likely to attempt credit card fraud in these scenarios.

The Payment Card Industry (PCI) has prohibited merchants from storing CVVs on their e-commerce websites. This protects you in the event the site is hacked and your data is breached. Even if someone has your credit card number, if they don't have the corresponding CVV, it's much harder to make unauthorized purchases with it.

By asking for the CVV code, the merchant is adding an extra level of security to ensure that the cardmember is the one making the purchase. That piece of your credit card information is not present in the magnetic stripe. Therefore, many common fraud schemes, such as skimming, won't work.

A PIN is a “personal identification number" and is created by the cardholder. It is typically four digits, though depending on your financial institution, it may be longer. Credit cards require PINs to execute cash advances. Both credit and debit cards use PINs for withdrawing cash from an ATM or making a purchase. PINs are different than CVVs.

A CVV is assigned by the credit card issuer and, unlike a PIN, the CVV is printed on your card.

Some high-profile e-commerce sites may not require a CVV to make a purchase because they already have other reliable security measures in place and don't want to add friction to the checkout process.

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. There are several reasons why a retailer may not ask for the CVV.

Some retailers may choose to skip CVV verification because they have other security measures in place to mitigate risk.

Address verification system (AVS) is an example of a verification tool that helps retailers to mitigate risk without asking for the CVV. It cross-references your address and compares it to the address on file for the card.

Some retailers simply have a higher risk tolerance than others. Depending on the size and profit margins of a certain retailer, they may decide to accept the risk of fraud or chargebacks. They're able to eat the cost and create a more seamless customer experience with no added friction during the checkout process.

Some retailers allow customers to use payment management systems that store your credit (or debit) card information for you.

Most prominent examples are Apple Pay, Google Wallet and PayPal. When these platforms are used to make a purchase, the payment management system handles verification and processing, so the online retailer doesn't see or obtain your credit card information.

In these examples, the CVV is likely on file with the payment management system, so you aren't required to enter it again to make a purchase. The CVVs are never kept on file by the retailers themselves.

Some retailers will only ask for your CVV the first time you make a purchase with them. If your transaction goes through successfully, your item(s) are delivered and there is no report of fraud, the retailer may assume that you are a genuine cardholder making a purchase. The next time you shop with that retailer online, unless you change your card number or shipping address, they may assume that you're the true cardholder and may not need to ask for the CVV.
