If you’ve recently used your credit card to pay for something over the phone or online, you would have been asked to provide a CVV number. CVV stands for ‘card verification value’, and is also sometimes referred to as a CVC or card verification code.
A CVV code is usually needed when the card is used online or over the phone as an anti-fraud measure. Without the cardholder being physically present to sign or verify the purchase, the CVV provides an extra layer of protection.
If you’re using Mastercard or Visa, the CVV is usually three digits and is located on the back of the card. If you’re using an American Express, the CVV is usually four digits and is on the front of the card.
