If you have booked accommodation that doesn't accept prepayment, but you prefer to pay in advance, please contact our Customer Service department and request prepayment options.
In most cases like this, the accommodation you have booked is a small business or private property and has no technical possibility to charge the credit cards.
In certain scenarios, the administration of the accommodation will provide you with their payment details or will issue an invoice for the prepayment.
You can find contacts of the Customer Service in your country here: https://www.booking.com/content/offices.html
Alternatively, you can reach out to the property directly, contact details are mentioned in the reservation confirmation.
