Understanding the 'File Number' in Your Passport Application

on

 When applying for an Indian passport, every detail matters. Among the various components in the process, the passport file number is one of the most crucial identifiers for tracking and managing your application. This guide will comprehensively cover everything you need to know about the passport file number, how to find it, what it means, and how it can help streamline your passport application process.

What is a Passport File Number?

The passport file number is a unique 12-character alphanumeric code assigned to every passport application. It serves as a tracking number that enables applicants and authorities to monitor the progress of the application. It is typically mentioned in the acknowledgment letter or receipt provided at the time of submission of the passport application.

This number is not random—it encodes details like the place of application and the year of submission. It is used by the Passport Seva system to search, verify, and process your request with precision.

Structure of the Passport File Number

Understanding the structure of the passport file number can help you interpret where and when your application was submitted. Here's a breakdown:

  • First 4 letters – Indicate the Passport Office code (e.g., DLHN for Delhi, HYD for Hyderabad).

  • Next 2 digits – Indicate the year of application (e.g., 24 for 2024).

  • Last 6 digits – This is the serial number assigned to your application (e.g., 004567).

Example: DLHN24004567

  • DLHN – Passport office Delhi

  • 24 – Application year 2024

  • 004567 – Serial application number

Where Can You Find Your Passport File Number?

You can find the file number in several documents and platforms related to your passport application:

  1. Acknowledgment Receipt: Issued when you submit your application either online or at a Passport Seva Kendra (PSK).

  2. SMS or Email Alerts: If you’ve registered a valid mobile number or email ID, you may receive the file number in a confirmation message.

  3. Passport Seva Portal Dashboard: By logging into your account on Passport Seva, the file number is visible in your application status.

How to Use the File Number to Track Passport Status

Tracking your passport status is simple with the file number. Follow these steps:

  1. Visit the Passport Seva Tracking Page

  2. Enter the file number along with your date of birth in the prescribed format.

  3. Click on “Track Status”

  4. The status will reflect stages like "Application Submitted", "Police Verification Initiated", "Passport Printed", or "Dispatched".

The file number is mandatory for tracking and resolving any delays or issues in processing.

Importance of the File Number in Passport Services

The passport file number is not just a tracking ID—it is your application identity in the entire passport issuance workflow. It is essential for:

  • Customer support interactions

  • Filing grievances or complaints

  • Verifying updates in case of discrepancies

  • Police verification coordination

  • Document resubmission or correction tracking

In case of any dispute or delay, quoting the correct file number helps officials locate your application instantly.

Common Mistakes Related to File Number

Errors related to the passport file number can lead to delays or status tracking failures. Watch out for:

  • Entering incorrect characters (e.g., typing "O" instead of zero)

  • Misplacing or losing the acknowledgment receipt

  • Wrong Passport Office Code

  • Typing errors during status checks

To avoid these, always store a digital copy of your acknowledgment and double-check the entered number before performing any actions.

File Number vs Passport Number: What's the Difference?

Many applicants confuse the file number with the passport number. These are two distinct identifiers:

  • File Number: Temporary, for tracking the application until passport issuance.

  • Passport Number: Permanent, printed on your issued passport (e.g., Z1234567).

After your passport is issued, the file number is archived, while the passport number becomes your official identity for international travel.

Lost Your File Number? Here's What to Do

If you’ve lost your acknowledgment receipt or file number, don't panic. Here's how you can recover it:

  1. Check your registered email/SMS inbox for original communications.

  2. Log in to your Passport Seva account to view past applications.

  3. Visit your nearest Passport Seva Kendra with valid ID proof to retrieve the number.

  4. Contact Toll-Free Passport Helpline at 1800-258-1800 for assistance.

It’s always recommended to keep multiple backups, both digital and physical.

Can the File Number Be Changed?

No, once a file number is generated, it cannot be altered. It is system-generated and linked to your original application data. However, if you cancel your application and reapply, a new file number will be issued based on your new submission.

Tips to Keep Your File Number Safe and Accessible

  • Take a photo of your acknowledgment receipt.

  • Email the details to yourself as a backup.

  • Save it in a secured cloud note or password manager.

  • Avoid sharing it publicly, as it can be used to access your application status.

Your file number is like your passport application fingerprint—keep it confidential and handy.
