Everyone registered with a GP in England and Wales has their own NHS Number.
We use your NHS Number along with your address and date of birth on your patient records, in letters and correspondence about your appointments or treatment and to check that we have the correct information about you and your health.
Each NHS Number is a unique 10-digit number that is printed on NHS medical cards. You get a medical card when you register with a GP. This 10-digit number has replaced other numbers that you may have had in the past.If you would like to find out your NHS number you can contact your GP practice. To protect your privacy, they may ask you to show them a passport, driving licence or some other proof of identity.
If you aren't registered with a GP, then you will not have an NHS number. To find your nearest GP practice, visit the NHS Choices website and enter your postcode. You will then be able to register with a GP close to where you live.
If you are a visitor to the UK, you will not be given a permanent NHS Number. More information on overseas visitors using the NHS is available here.
