CSC, or Card Security Code, is a three or four-digit number found on credit cards. It serves as an additional layer of security for online and card-not-present transactions. In this article, we will delve deeper into what CSC is, where it is located on a credit card, and its importance in preventing fraudulent activities.
What is CSC?
The Card Security Code, also known as the Card Verification Value (CVV), Card Verification Code (CVC), or Card Identification Number (CID), is a unique three or four-digit number printed on credit cards. It is not embossed like the card number, making it difficult to obtain through physical means. The CSC is primarily used to verify that the person making the transaction has the physical card in their possession.
Where is CSC located on a credit card?
The location of the CSC on a credit card varies depending on the card issuer. For most Visa, Mastercard, and Discover cards, the CSC is printed on the back of the card, usually in the signature panel. It is the last three digits following the credit card number. American Express cards, on the other hand, have a four-digit CSC printed on the front of the card, above the card number.
Importance of CSC
The CSC plays a crucial role in preventing fraudulent activities, especially in online and card-not-present transactions. By requiring the CSC during a transaction, merchants can verify that the person making the purchase has the physical card in their possession. This adds an extra layer of security, as even if a fraudster manages to obtain the credit card number, they would still need the CSC to complete the transaction.
Furthermore, the CSC is not stored in the magnetic stripe or chip of the credit card, making it less vulnerable to skimming or other methods used by criminals to steal card information. This ensures that the CSC remains confidential and known only to the cardholder.
Using CSC Safely
To ensure the safe use of the CSC, it is essential to follow certain best practices:
Do not share your CSC: The CSC should be kept confidential and not shared with anyone. It should only be entered on secure and trusted websites during legitimate transactions.
Protect your credit card: Keep your credit card physically secure to prevent unauthorized access. If your card is lost or stolen, report it to your card issuer immediately.
Be cautious of phishing scams: Be wary of emails or messages that request your CSC or other sensitive information. Legitimate organizations will never ask for your CSC via email or text.
Check for secure connections: When entering your CSC online, ensure that the website has a secure connection. Look for “https://” at the beginning of the URL and a padlock icon in the browser address bar.
