What Is This?
For your protection, the 3-digit Credit Card Verification number on your credit card is required for processing. All credit card cards now being released have a three digit Credit Card Verification number issued on them.
The 3-digit Credit Card Verification number is usually printed on the signature panel on the back of the card immediately after the card number or partial card number. For simplicity, the Credit Card Verification number is always the last 3 digits shown on the signature panel.
