A travel document number is a unique identifier associated with travel documents like passports, visas, and Green Cards. It is used by government agencies to track tourists, ensure the validity of the documents, and identify travelers as eligible to travel abroad. In the United States, the travel document number can be found on different types of documents, such as passports, visas, and Green Cards. For example, in a passport, the travel document number is a 9-digit number located in the top right-hand corner, while in a visa, it is often printed in a different color, such as red, on the bottom right-hand corner. Additionally, the U.S. Citizenship and Immigration Services (USCIS) issues various types of travel documents, including advance parole documents, refugee travel documents, re-entry permits, TPS travel authorizations, and carrier documentation, depending on an individuals immigration status or pending application for an immigration benefit.
