Information about your NHS Number


Everyone registered with the NHS in England and Wales has their own unique number.

  •  Your NHS Number is unique to you
  • Using it to identify you correctly is an important step towards your patient safety
  • It helps to create a complete record of your care linking every episode of your care across NHS organisations
  • It enables your healthcare information to be safely transferred and accessible to other NHS organisations, for example – needing hospital treatment when on holiday away from home

What is my NHS Number?

The NHS Number is normally shown in a '3-3-4' format e.g. 943 476 5919 (this is an example number only). The 10-digit NHS Number was introduced in 1996 and replaced different versions that included both letters and numbers.


Why do we request your NHS Number for registering with us?

Using your NHS Number is a better way of finding your information than using just your name and date of birth, particularly with computer systems. It will help to avoid mistaking you for another person which can be caused by errors such as misspelt names or by people having the same or similar names and the same date of birth.


Finding your NHS Number:

You should be able to find your NHS Number from the following sources:

  • on a letter or other document from the NHS, including a letter from your GP practice or a hospital
  • on a printed prescription
  • If you are registered with a GP practice they should be able to give you a note of your NHS number on your request

Reasons you may not have an NHS Number

You may not have an NHS number if:

  • You have never been registered with a GP practice in England, Wales or the Isle of Man
  • Have never received any NHS treatment
  • Were not born in England, Wales or the Isle of Man

When you register with a GP practice they will check whether you have an NHS Number and if not you will be given one.
