Although there is evidence of passport-like documents dating back to around 450 B.C., there wasn't a standardized set of guidelines for them until the 1980s. These keys to exploring the world come in several different types. Ordinary passports are issued to tourists for travel. Official passports, or service passports, are given to government workers for job-related travel. Diplomatic passports are issued to diplomats and come with privileges like diplomatic immunity. Emergency passports might be distributed if a person loses his or her passport and there is not time to get a replacement.
