Do you need your passport number to book an international flight?

You don't need a passport number to book an international flight. However, make sure to leave enough time for a passport renewal or a new application because it can take a while to process. If you think you're going to travel internationally, we recommend applying as soon as possible to have a passport ready.

Passport books are required as identification verification for international air travel. Passport cards serve that purpose but can only be used for land travel into the U.S. from specific destinations. Travelers can apply for one or both documents, as they both are acceptable as U.S. citizenship identification.
