What Is a Security Code?
A security code is a 3-digit or 4-digit code printed separately from the credit card number. It is not printed on credit card statements. Entering the security code verifies that the customer actually possesses the physical card and prevents fraudulent usage by a third party.
- The security code is not a PIN number.
