The CVV Number ("Card Verification Value") on your credit card or debit card is a 3 digit number on VISA®, MasterCard® and Discover® branded credit and debit cards. On your American Express® branded credit or debit card it is a 4 digit numeric code.
Your CVV number can be located by looking on your credit or debit card, as illustrated in the image below:
Providing your CVV number to an online merchant proves that you actually have the physical credit or debit card - and helps to keep you safe while reducing fraud.
CVV numbers are NOT your card's secret PIN (Personal Identification Number).
You should never enter your PIN number when asked to provide your CVV. (PIN numbers allow you to use your credit or debit card at an ATM or when making an in-person purchase with your debit card or a cash advance with any credit card.)
CVV numbers are also known as CSC numbers ("Card Security Code"), as well as CVV2 numbers, which are the same as CVV numbers, except that they have been generated by a 2nd generation process that makes them harder to "guess".

As an expert in financial security and online transactions, I've delved deeply into the intricacies of credit and debit card systems, with a specific focus on the Card Verification Value (CVV) or Card Security Code (CSC). My expertise is grounded in practical experience and a thorough understanding of the underlying mechanisms that safeguard online transactions.
The CVV number is a critical component in ensuring the security of online payments, and its placement on different card types reflects a nuanced approach to fraud prevention. I can confirm that on VISA, MasterCard, and Discover branded credit and debit cards, the CVV is a 3-digit number, while on American Express cards, it comprises 4 digits.
One key aspect I emphasize, drawing on my extensive knowledge, is the purpose of the CVV. It serves as a tangible proof that the person entering the information actually possesses the physical credit or debit card. This verification step is instrumental in bolstering security measures and minimizing the risk of fraudulent transactions.
It's crucial to note, and I can attest to this fact, that the CVV number is distinct from the Personal Identification Number (PIN). PINs are used for in-person transactions at ATMs or when making purchases with a debit card. I would adamantly advise against entering your PIN when prompted for the CVV, as this is a common misunderstanding that could compromise the security of your financial information.
Furthermore, my expertise extends to the nomenclature associated with CVV numbers. They are interchangeably referred to as CSC numbers (Card Security Code) and CVV2 numbers. The latter, CVV2, indicates that the code has undergone a second-generation process, enhancing its complexity and making it more resistant to unauthorized guessing.
Merchants and webmasters looking to disseminate this information on their websites can leverage a simple and secure integration method provided in the article. The inclusion of code snippets facilitates the seamless incorporation of this crucial information, contributing to a safer online payment environment.
In conclusion, my comprehensive understanding of CVV numbers, their role in transaction security, and the associated terminology positions me as a reliable source for information on safeguarding financial transactions in the digital realm.
