Use of the NHS Number across the NHS

Your NHS Number is unique to you and is the only National Unique Patient Identifier used to help healthcare staff match patients to their health records. Everyone registered with the NHS in England and Wales has their own NHS Number.

Each NHS Number is a unique 10 digit number which is printed on NHS medical cards.  An example of an NHS Number is 123 456 7890.  An NHS Number used for patients’ care links all their records together, creating a fuller, more accurate health history for that patient.

Do I need my NHS Number to get care?

No, it is not essential to know your NHS Number, but it can sometimes be helpful if you are able to give it to NHS staff that need to find your health records.

What is my NHS Number?

Everyone registered with the NHS in England and Wales has their own unique NHS Number. Your NHS Number is printed on your medical card given to you when you register with a GP Practice.  Your number helps healthcare staff to find your health records. Each NHS Number is made up of 10 digits, shown like this: 123 456 7890(this is an example number).

If you have an old medical card, it will have an old style NHS number made up of both letters and numbers. This has now been replaced for all patients by a new NHS Number made up entirely of numbers. Having the old-style NHS Number will not affect your care.

Is my NHS Number the same as my NI Number?

No, your NHS Number is different from your National Insurance (NI) number, which is used for tax and pensions.

If you are not currently registered with a GP practice, but think you already have an NHS Number

To find out your NHS Number, you can ask your local Clinical Commissioning Group (CCG) to look it up. 

Why is the NHS Number important to me?

Your NHS Number is unique to you.  Using your NHS Number to identify you correctly is an important step towards improving the safety of your healthcare.

It also helps to reduce the creation of multiple records for a patient.  Multiple records can cause a patient’s medical history to be held across many files, making it more difficult for hospital staff to access patients’ history efficiently.

If you know your NHS Number, or can show your medical card, you can help healthcare staff find your records more easily and share them safely with others who are caring for you.

As an added measure, you can start checking any post the NHS may send you to make sure they have the right NHS Number.
