Where is the Passport Serial Number Located?

The passport serial number is located on the first or second page of your passport, often referred to as the identification page.

Why is it Important to Keep Your Passport’s Serial Number Safe?

Your passport’s serial number is a valuable tool for fraudsters and criminals, particularly when combined with other pieces of personal information. Identity theft is becoming increasingly widespread and can cause significant financial and social damage to those impacted. Fraudsters can use stolen passport information to access financial accounts, apply for loans and credit cards, complete transactions on social media, and even commit crimes under your name.

It’s critical, therefore, that you protect your passport and its serial number from theft, damage, or loss. Keep your passport in a secure location and never lend it to anyone or leave it lying around. Carry it with you at all times, particularly when travelling, and avoid sharing its serial number on public platforms or social media.

What to Do If Your Passport Serial Number is Lost or Stolen

If your passport’s serial number is lost or stolen, it’s essential to take immediate action to protect your identity and prevent the misuse of your personal information. Firstly, report the lost or stolen passport to the authorities, who will issue you with a replacement passport.
