Signature Strip Number

 

Credit and Debit cards

The Signature Strip Number is a 3-digit security code that is printed on the back of your credit or debit card.

The signature strip may contain your entire account number or just the last four digits of your account number. Either way, the Signature Strip Number will appear after the last four digits of your account number.

The Signature Strip Number is used to verify that you have possession of the credit card you are attempting to use.

 

American Express

The Signature Strip Number is a 4 digit, non-embossed number printed above your account number on the face of your card.

My sincere thanks to Linguaphone. You have helped me learn this language for my work.
