Check your settings
Often, the default setting is to not send CVC codes, especially if you are new to Booking.com. If this is the case, and you need the codes for your business operations, please contact the Booking.com team to update this.
It’s good to remember that requesting CVC codes can reduce the conversion rate of bookings at your property, as customers generally prefer to provide fewer details.
AMEX and other cards
We don’t request CVC codes from AMEX card users.
If the card is not AMEX and the issue is affecting more than one booking, please contact your channel manager to ensure that CVC code details are being passed from them to you.
If your channel manager isn’t receiving these codes, they can contact the Booking.com team to change this.
