is the security code on an amex card on the front or back
Most websites just ask for a âsecurity codeâ and provide a small box for you to type the code into. On Visa, MasterCard, and Discover cards, the code is a three digit code on the back of your card. The preceding four digits (â3456â in the image above) are the last four digits of your card number. On American Express cards, the security code is a four-digit code on the front of the card. Look above your card number on the right side of the card. Your security code, like all the other numbers on your card, is a critical piece of information.
