What is the difference between passport number and reference number?

Passport Numbers vs. Reference Numbers: Understanding the Difference

Applying for a passport can be a complex process, often involving multiple stages and identifiers. Two numbers frequently appear – the Passport Reference Number (PRN) and the Passport File Number (PFN) – and understanding their distinctions is crucial for tracking your application and managing your passport. These are not interchangeable, and their uses are quite different.

The Passport Reference Number (PRN) is a temporary identifier assigned to your passport application immediately upon submission. Think of it as a tracking number for your application’s journey through the processing system. This number allows you to check the status of your application online or via phone, providing updates on its progress – whether it’s been received, is being processed, or is ready for collection. Crucially, the PRN is only valid during the application process. Once your passport is issued, the PRN becomes obsolete.

In contrast, the Passport File Number (PFN), sometimes also referred to as the Passport Number, is a unique alphanumeric identifier assigned to your issued passport. This is the permanent, official number associated with your passport itself, printed directly on the document. It’s the number you’ll use for international travel, visa applications, and any other official purposes requiring passport identification. Unlike the temporary PRN, the PFN remains permanently linked to your passport throughout its validity period.

To illustrate the difference, imagine applying for a passport online. You submit your application and immediately receive a PRN, allowing you to monitor its progress. Weeks later, your passport is ready. You then receive your passport booklet, which contains the PFN. The PRN served its purpose in tracking the application, but the PFN is the number that will identify your passport for years to come. Trying to use the PRN after passport issuance will yield no information.

In short:

• PRN (Passport Reference Number): Temporary, application tracking number. Used before passport issuance.
• PFN (Passport File Number): Permanent, official passport number. Printed on the passport and used for identification after issuance.

Understanding this distinction avoids confusion and ensures you can effectively manage your passport application and utilize the correct number for the appropriate purpose. Always refer to the specific instructions provided by your passport issuing authority for detailed information on tracking your application and using your passport number.
