What is a travel document number?

A travel document number is a unique identifier assigned to an individual's passport or other travel documents. It is usually a combination of letters and numbers that help immigration authorities and airlines verify the authenticity of the document and the identity of the traveler.

The travel document number can be found on the main page of a passport, typically located near the top right corner. It is important to keep this number confidential and secure, as it can be used to access personal information and travel history.

Having a valid and correctly entered travel document number is essential for international travel, as it is used to check in for flights, pass through immigration control, and enter foreign countries. It is important to double-check the accuracy of the travel document number before travelling to avoid any issues or delays.
