CVV check

The card verification value (CVV) appears on credit and debit cards. It is a three-digit number on Visa, MasterCard and Discover branded cards, and a four-digit number on American Express cards. Running a CVV check adds an additional layer of fraud protection to your payments.

As standard, our payment gateway requires merchants to include the payment card's CVV when sending a payment with either a card token or full card details.

The CVV is not required when sending a payment with source ID or a default card, but you still have the option of adding the CVV if you wish. However, when you include the CVV in a request, it is subject to verification – if it does not match, the request will fail.

CVV check configurations

There are two possible configurations for using the CVV check in your payments: CVV required and CVV optional.

CVV required

If the CVV is required, you must include it for all payment request types, except for those using a source ID. If the payment contains incorrect or missing CVV information, the request will fail.

CVV optional

Where the CVV is optional, you can send any type of payment request with or without the CVV. However, if you include the CVV in a payment request, it will be subject to verification. If it's incorrect, the payment will not be successful.
