What Is a Travel Document Number?


If you plan to travel abroad, you’ll need a lot more than your belongings. You’ll need valid identification based on the country you’re traveling through or to. Every country differs, and the documentation you’ll need may vary, but one thing they all have in common is the travel document number.

Whether you carry a passport, visa, or other federal ID, each document has a travel document number. This is the number the government uses to ensure the document is valid and not fake.

Government agencies use these numbers to track tourists, keep the borders safe, and identify you as a traveler, ensuring you’re eligible to travel abroad.

Types of Travel Documents 

Before you travel, it’s important to find out what type of travel documents you need. Here are the most common.


Most people know what a passport is. It allows you to travel from your citizen country to countries abroad. It identifies you no matter which country you travel to as it’s a universally used document. 

You’ll use the passport to get through customs both in your home country and when you arrive at your destination. Your passport is often the first step to getting a visa if a visa is required to enter the country you plan to travel to. Even if you aren’t sure if you’ll need a visa or not, start with the passport as it’s the first step.

The Passport Travel Document Number

Every passport has a travel document number. You can find it in the top right-hand corner of the passport. It’s a 9-digit number, and no two passports have the same number.

Since a passport isn’t enough to visit every country, you may need a visa too. A visa is required to visit countries where you aren’t a citizen and passports aren’t accepted. In the United States, the USCIS determines who gets a visa to come into the United States. 

A visa is more detailed than a passport. It tells you what you’re allowed to do when you’re in a foreign country and how long you’re allowed to stay. To get a visa, you must get it from the country’s consulate you plan to visit, but in the United States. 

Before you apply for the visa, think about why you need it. Will you work in a foreign country or will you be a tourist? There are different types of visas based on your intentions. The visa process can take a while, so make sure you have all supporting documentation and pay close attention to the dates of your interview or other important dates.

To apply for a visa, you’ll need the visa application, which you can usually find online, your passport, application fee, and photo. You may also need to provide a reason for your trip and prove you have the finances to cover the cost of the trip. 

At the visa interview, you’ll answer questions and provide your fingerprints (usually digitally). If there’s further documentation needed, you’ll find out then. Otherwise, you should receive your visa shortly afterward.

The Visa Travel Document Number

You’ll find the Visa travel document number easily because it’s usually in a different color than the rest of the visa. In the United States, it’s on the lower right corner.

Green Card

After you have a visa, you’ll need a Green Card if you want to become a permanent US resident. The USCIS issues the Green Card upon approval. However, you’ll still need a passport since Green Card holders aren’t citizens. A Green Card may make it easier to travel back and forth from your birth country to the US, smoothing the process along.

To apply for a Green Card, first, determine your eligibility and then complete application I-485. Like the visa, the USCIS will schedule an interview and determine your eligibility. 

The Green Card Travel Document Number

You can find your Green Card travel document number on the back of the Green Card.
