The confirmation number is the standard identifier used to confirm and track reservations in travel services. When a customer makes a booking—whether for flights, hotels, car rentals, or other travel-related services—they receive a confirmation number as part of their reservation details. This number is unique to each booking and is key in ensuring that the travel provider and the customer can easily reference the specific reservation in question.

The confirmation number allows customers to manage their bookings, make changes or cancellations, and check their reservation status. Its clarity and uniqueness make it the most reliable method for identifying a reservation, ensuring that the correct details are retrieved without confusion.

While options like verification codes, booking IDs, and reference numbers can also be used in various contexts within travel services, they do not universally serve the same purpose or are not always employed as the primary means of identification for a specific reservation in the same way the confirmation number is.
