What is a "Confirmation Number" used for?

A "Confirmation Number" is primarily used to verify a cardholder's reservation. In the context of transactions, particularly those involving services (like hotel bookings, flight reservations, or event tickets), a confirmation number serves as a unique identifier that ties the customer to their specific reservation.

When a customer completes a reservation, whether online or over the phone, they receive this number as proof of their booking. It allows both the customer and the service provider to refer to the same transaction. In case there are inquiries or issues regarding the reservation, the customer can present this confirmation number, making it easier for customer service representatives to access the related information quickly.

While confirmation numbers can sometimes relate to financial transactions, their primary purpose in the context of this question is verification of reservations. This helps ensure that services or products are allocated to the right individuals, ultimately enhancing customer satisfaction and service efficiency.
