Does Your Passport Number Change When You Renew UK

The passport number changes when you renew your UK passport. Learn more about what happens to the number when you renew or get a new passport.

What is the passport number?

The passport number is a unique identifier assigned to each passport issued by the United Kingdom. When you apply for a new passport, the government will assign a new passport number to you. In most cases, your old passport number will remain the same when you renew your passport. However, if your name has changed or if you are renewing for an adult child under 18 years of age, the government may issue a new passport with a new number.

How do I find my passport number?

If you have lost your passport, or if it has been stolen, you can find out what its passport number is by contacting the Passport Office.

How do I find my passport number

To do this, you will need to:

  • Complete a passport application form
  • Carry your original passport with you when you visit the Passport Office
  • Provide your name, date of birth, and nationality
  • Provide a copy of your ID ( driver’s licence, passport, etc.)
  • Pay the required fees

The Passport Office will then ask for your address and contact details, which you can either provide on the application form or on a separate sheet of paper. The Passport Office will also ask for the confirmation number found on the back of your original passport. If you can’t remember the confirmation number, don’t worry – the Passport Office can usually find it out from your original passport. 

How Does a Passport Number Affect Renewal?

When you renew your passport, the number on the front of the document will change. This is because the UK’s ID card system now uses a citizen’s passport number as part of their unique identification number. If you want to keep your old passport number when you renew, you’ll need to take steps to do this. For example, you can request that your old passport be reissued with a new number or request that your current passport be upgraded to a new version with a new passport number.

Impact of Not Renewing Your UK Passport on Travel

If you’re not planning on traveling during your upcoming passport renewal, you may want to think again. The fact is, if your passport expires without being renewed, the number on the document will change from your current passport number to a new number. This can make traveling abroad difficult or even impossible.

If you’re unsure whether or not your passport will expire before it’s time for your renewal, you can check with the British Embassy or Consulate nearest you. However, keep in mind that if your passport does expire before your renewal is due, it may be difficult to get a new one in time to travel.
