Debit card security code

A debit card security code (CSC) is a three or four-digit number that appears on your debit card. It may also be referred to as a CVV or CVC, which indicates card verification value and card verification code, respectively.

Where is the security code on a debit card?

The security code can be found on the front or back of a debit card, depending on the payments service your bank uses. With Chase debit cards, the three-digit code appears on the back of the card to the right side of the white signature strip.

Is a CVV number the same as a debit card number?

The CVV is distinct from the debit card number. The debit card number most often appears on the front of the card and is 15 or 16 digits long. In addition, debit cards use a PIN, or personal identification number, which is typically four digits you choose yourself. The PIN does not appear on the card, and it’s typed into a keypad when you withdraw money from an ATM or pay for a purchase in person at a cash register, for example. Do not share your PIN or write it on your card. The combination of a debit card security code and PIN can help to prevent debit card fraud.

How does a debit card security code work?

A debit card security code is frequently used in online and phone transactions to provide an added layer of security. The reasoning behind using a debit card security code is that you’ll typically need to have the card in hand in order to provide the CVV number.

The bottom line

Most often you can find a debit card security code on the back of your debit card. Not to be confused with a debit card number or a PIN, a debit card security code serves a unique function of helping to protect your account when making online and phone-based purchases, for example.
