How to Find the File Number in an Indian Passport?

No, you cannot change your file number. If you have got your file number, then it is impossible to change, and you need to process through the same number for your application. However, if you want a new file number, then you will need to apply for an Indian passport application, for example, renewal or re-issue of a passport. In that condition, you can get a new file number.

Through the file number, I have checked my Indian passport status by going to the website of the Passport Seva Portal.

1. Clicked on the Track application status
2. Selected my application type. 
3. Entered file number and date of birth. 
4. Then clicked on the view button to see the current real-time status of my passport application. 

A file number includes information like city and state codes, the year of application submitted, and a unique application digit, which makes your application unique from other applicants.

Yes, the file number on an Indian passport is very crucial because: 

• It helps you to track the status of your Indian passport application. 
• It is also a valid proof that your Indian passport has been registered. 
• For instant help or a query related to your passport, you can make it faster by submitting your file number.
