Card Verification Number (CVN)

A three-digit security number that usually appears on the back of your credit or debit card. Sometimes called a card security code or card verification value, it provides extra protection against fraud.

  • When asked for your CVN, be sure to enter it properly or your payment might not be successful.
  • CVNs can appear in different spots on each card. Often, you can find your CVN on the back of your card, near or next to the area where you can add your signature. Some cards show it on the front, near your account number.
  • It's a good idea to add a backup credit card to your AdWords account in case there's ever a problem with your primary form of payment.
