Passports are official documents issued by governments to identify a person during international travel. They include details such as a person’s name, photograph, nationality, date of birth, and passport number. Passports are used to confirm identity when entering or leaving a country.

Passports are used at borders, airports, seaports, and embassies around the world. They are carried by travelers moving between countries. Modern passports became more common in the 19th and 20th centuries and are still used today.
