What is the credit card ID number?
Answer:
Using the Credit Card ID Number for Advanced Security
To further ensure your privacy and protection, credit card companies have begun using an additional 3 or 4 digit Card ID Number on your credit card. This number is called a Card Verification Code (CVC) code by MasterCard and a Card Verification Value (CVV) by Visa.
To prevent fraud, your Card ID Number does not appear on your receipt, nor is it retained by our database. It appears only on your credit card, as a security measure to prove that users have the card on their person when making a purchase.
How to find the Credit Card ID Number on your card
- MasterCard/Visa/Discover: Your Credit Card ID Number should be the last block of digits in your account number, directly below your signature on the back of your card.
- American Express: Your four-digit Credit Card ID Number should appear on the upper right of the front of your card.
