If you’re a frequent traveler, you’ve probably heard of the term “passport book number”. But what exactly is this, and why is it important? Knowing what a passport book number is and how to use it can make the process of crossing borders and obtaining visas much easier.
What Is a Passport Book Number?
A passport book number is a unique number assigned to each passport holder. It consists of nine digits, which are divided into two parts. The first part consists of two letters followed by seven digits. The letters indicate the country of issuance, while the seven digits are the unique identifier of the passport holder. The second part is a check digit, which is used to verify the accuracy of the passport number.
Where Can the Passport Book Number Be Found?
The passport book number is printed on the data page of the passport, which is located at the back of the book. This number is also commonly referred to as the passport serial number.
Passport Numbers vs. Passport Book Numbers
A passport book number is not to be confused with the passport number that is printed on the cover of the passport. The difference is that the passport number is an alphanumeric code that is used to identify the passport itself, while the passport book number is the unique identifier of the passport holder.
What Is the Passport Book Number Used for?
The passport book number is used for a variety of purposes. It is used to verify the identity of the passport holder when crossing borders or obtaining visas. It is also used to ensure that the passport holder is not using someone else’s passport.
In addition, the passport book number is also used to track the passport holder’s travel history. This information can be used by the issuing country to ensure that the passport holder is adhering to immigration laws and to track down any fugitives. It is also used by immigration officials to verify the identity of the passport holder.
Finally, the passport book number can also be used to check the validity of a passport. By entering the passport book number into the online checking system, you can determine if the passport is valid or not.
Does Every Country Use the Passport Book Number System?
Different countries have different passport book number systems. Each country has its own set of rules and regulations regarding passport book numbers, so you should always check with the issuing country to make sure you have the correct number.
Additionally, some countries don’t make use of the system at all. If you are traveling to a country that does not use the passport book number system, your passport number will be the only method of identification you will need to provide. Here is a list of countries that make use of passport book numbers:
- South Korea
- United Kingdom
- United States

How Should You Use the Passport Book Number?
When entering the passport book number into an online system, make sure that you enter it correctly. Double-check that all the digits and letters are correct, as a single mistake can lead to an inaccurate result.
If you are traveling to a foreign country, make sure to bring your passport book number with you. This will be necessary when crossing borders or obtaining visas.
You won’t need to use your passport book number on a regular basis. But knowing what it is and how to use it can make the process of crossing borders and obtaining visas much easier. Make sure to keep it safe and never share it with anyone else.
