The CVV card security code is a three or four-digit number printed on the back of your credit or debit card. This code is used for an additional layer of security when you make online purchases. It is not stored on the magnetic strip of your card, so it is not readily available to hackers.

Here’s a breakdown of the CVV code:

• Three digits: This is the most common format for the CVV code. It is located in the signature panel on the back of your card, between the embossed card number and the expiration date.
• Four digits: This format is sometimes used for international cards. It is also located in the signature panel on the back of your card.
• Not on the magnetic strip: Important: The CVV code is not stored on the magnetic strip of your card. It is a separate security feature that is used specifically for online purchases.

Here are some of the ways the CVV code is used:

• Online purchases: When you make an online purchase, the website will ask you to provide your CVV code as part of the checkout process.
• Payment apps: If you use payment apps like Apple Pay or Google Pay, the CVV code may be required when you set up the app or when you make a purchase.
• Telephone orders: When you call a company to place an order over the phone, the merchant may ask you for your CVV code as a security measure.

Here are some tips for protecting your CVV code:

• Do not share your CVV code with anyone. This includes anyone who claims to be from your bank or credit union, or anyone who asks you for your CVV code via email or text message.
• Do not write your CVV code down on anything: This includes sticky notes, post-it notes, or your computer.
• Be careful when using public Wi-Fi: Public Wi-Fi networks can be insecure, so it is best to avoid using your CVV code when you are connected to public Wi-Fi.

If you think your CVV code has been compromised, you should contact your bank or credit union immediately.
