What is a Card Security Code?
Your Card Security Code is the last 3 digits on the signature strip on the reverse of all NatWest cards, and forms part of an additional verification service offered to suppliers to help combat fraud where you’re not making your purchase face to face. For example, when you purchase by telephone or over the Internet. This information, together with statement address details, may be checked during authorisation in order to confirm you have possession of the card itself.
Your Card Security Code is the last 3 digits on the signature strip on the reverse of all RBS Commercial cards, and forms part of an additional verification service offered to suppliers to help combat fraud where you are not making your purchase face to face, for example when you purchase by telephone or over the Internet. This information, together with statement address details, may be checked during the normal authorisation procedure in order to confirm that you have possession of your card before proceeding with the transaction.
The Card Security Code (CSC) is a 3- or 4-digit number printed on your credit card. It provides added security when you use your card on the Internet or over the phone. The number appears only on the card itself, not on receipts or statements. We ask for the CSC when you enter your payment information. This helps ensure that anyone placing an order with SteelNavel.com has the card in his or her possession and is not using a stolen credit card number. For Visa, MasterCard and Discover Cards Turn the card over and look at the signature box. You will find either the entire 16-digit credit card number or just the last 4 digits, followed by the 3-digit CSC. For American Express Cards The CSC is always located above the account number on the face of the card, sometimes on the left side and sometimes on the right. Note: Some American Express cards have a 4-digit number below the account number. This is not the CSC.
The “csc” is the last 3 digits in the row of numbers printed along the signature line on the back of the credit card(Visa, Discover, Mastercard). This 3-digit number is required in order to obtain credit card authorization. American Express users look for the 4-digit code printed on the front of your card just above and to the right of your main credit card number. This 4-digit code is your Card Security Code.
