A travel document number is a unique identifier associated with travel documents like passports, visas, and Green Cards. It is a set of digits that helps authorities recognize each individual traveling and is used to track tourists, keep the borders safe, and identify travelers, ensuring they are eligible to travel abroad. The travel document number is used to verify the authenticity of the document and to ensure that it is not fake. It is also required when applying for visas or traveling to certain countries.

Every passport, visa, or other federal ID has a travel document number. The travel document number is usually located on the most important page of any passport, the personal information or data page, the one with your photo. It is found in the top right-hand corner of the passport and is a 9-digit number. The visa number on your visa is often printed in a different color, and in the United States, it is on the lower right corner. The visa number is also the travel document number.

It is important to note that each travel document has a specific number of digits, and a Green Card number starts with three letters, while a U.S. visa number has a total of 8 numerical digits. The travel document number is different from the visa control number, which is also located on the visa but serves another purpose.

In summary, a travel document number is a unique identifier assigned to travel documents like passports, visas, and Green Cards. It is used to verify the authenticity of the document and to ensure that it is not fake. The travel document number is usually located on the most important page of any passport, the personal information or data page, the one with your photo. It is important to ensure that the travel document number on the visa matches the traveler’s actual travel document to avoid any issues during the immigration process.
