What is CVV Number in Credit/Debit Card? 

Let us begin with the full form of CVV – the abbreviation CVV stands for "Card Verification Value". CVV means the 3–4-digit unique numeric code assigned to each card by the card provider.  

Thinking can CVV be 4 digits? Check the next section and understand:  

Where Is the CVV Located on a Debit or Debit Card? 

Card provider	Number of Digits on CVV	Where to find CVV Number
Rupay, Mastercard, Visa, and Discover	3	Backside of the card (near the signature line)
American Express	4	Frontside of the card

How Is A CVV Number Generated? 

Issuing banks generate the CVVs based on  

1. Card number 
2. Card expiry date  
3. Service code 
4. Unique code of the bank 

It means that forging CVV number is not possible through your card details.  

CVC, CSC, CIN, CVD, CSC – Serving the Same Under Different Names 

Now, let’s check out some variations of CVV in the table below: 

Security code	Full form	Vendors
CVC/CVC2	Card verification/validation code	MasterCard
CSC	Card Security Code	American Express
CIN/CID	Card Identification Number	American Express and Discover
CVD	Card Verification Data	Discover
CSC	Card Security Code	American Express

RuPay and Visa cards mostly come with a CVV or a CVV2 code; however, all these serve the same purpose. 

What Does A CVV Number Contain? 

The components of CVV Number are: 

A magnetic strip 

The magnetic strip contains unique information about the card – magnetic reader reads this stripe when you swipe any card through it to authenticate the card. This strip hides the initial digits of the CVV.  

A 3-4 digit number  

It is the visible 3-4 digits after the strip which we call the CVV code. This set of numbers makes online transactions ultra-secure.  

Wondering what does the CVV actually do? Jump to the next section:  

What Is the Purpose of CVV?  

CVV is a guard to the money in your account against any fraudulent activities. It ensures that anyone who knows the card number, expiry date, and account holder’s name cannot make the online transaction.  

Only the person having the card or remembering the CVV can enter this by checking it. And after this step, PIN or OTP (sent to the registered mobile number) will be asked to make the payment. So, online payment through card is like a multi-layer security system to prevent fraud and CVV stands as the second layer of this system.  

While making offline payments through cards,  

• The cardholder manually inserts the card 
• The machine automatically reads the CVV  
• On entering secret PIN, the amount gets withdrawn  

Key Takeaway:  

• CVV is not at all required for offline transactions – beware if you are asked to do so  

Why Are You Asked to Enter the CVV? 

Well, a cardholder is asked to enter the CVV only when they are making any online transaction using their cards. Before asking the CVV, the card details like the card number, expiry day, and cardholder name are asked.  

After that, CVV is asked to verify whether you own the card or somehow came across the other details of it.  

When Should You Share Your CVV and When Shouldn’t? 

Any transaction done through a card will need a CVV – be it online or offline. During the offline transaction, the machine reads it automatically from the magnetic strip. 

However, during online transactions, you will see that you need to enter CVV after entering the card number and expiry day, to process the transaction. This is where you have to manually enter the CVV.  

How Safe the CVV Itself Is?  

CVVs are safe until someone has cloned the card along with its magnetic strip. Online payment gateways cannot save your CVV as it is against Per Payment Card Industry Data Security Standards. You can save all your card details on the payment portal of any app or website; however you cannot save CVV. You have to enter it everytime you want to transact using a card. Therefore, payment portals do not save your CVVs during online transactions. Just like that during card swipes, the machines do not save CVVs.  

Relax, fraudsters will have no access to your CVV during card swipes or online transactions. Incorrect CVV cancels the card authorization, thereby, there will be no transaction. So, there will be minimum chances of card misusing with CVVs.  

CVV Vs Card PIN 

PIN is at the third protection layer whereas CVV is at the second layer. The basic differences between PIN and CVV are 

• PINs are changeable – you have to change the PIN after your card is active (your banks will instruct you to do so for the first time, and it is safe). But CVV is not changeable.  
• PIN helps in the transaction itself whereas CVV helps in card verification purposes. 
• On entering the wrong PIN, there will be no transaction at all; however, the wrong CVV will pause the authentication process itself which will again result in no transaction.
