How to Find Your NHS Number (UK)

Your NHS number is a unique 10-digit number, formatted like 485 777 3456. It applies if you're registered for NHS care in England, Wales, or the Isle of Man. It's not the same as your National Insurance number, and giving a receptionist your NI number instead won't help them find your medical file.

1. Check any letter or document from the NHS. Appointment letters, prescriptions, hospital referral letters, and test results usually display it clearly.

2. Use the NHS "Find your NHS number" online service. This is the official tool for retrieving it if you don't already know it, and it sends the number to you by text, email, or letter once your identity is confirmed.

3. Log into your NHS account or the NHS App, where your number is displayed on your account or home screen if you've already registered.

4. Call your GP surgery and ask them to look it up. They may ask for proof of identity, such as a passport or driving licence, before disclosing it.

1. Download the NHS App or go to the NHS website and log into your NHS account.

2. Sign in using your NHS login credentials, verifying your identity if it's your first time.

3. Your NHS number is typically displayed on your account home screen or profile page once logged in.

If you've never registered with a GP practice in England or Wales, you may not have an NHS number yet. Registering with a local GP will generate one for you as part of the process — search for a nearby practice on the NHS website by entering your postcode, then complete registration either online or in person.

- England and Wales use the standard 10-digit NHS number.

- Scotland uses an equivalent called the Community Health Index (CHI) number, also 10 digits, found on letters from NHS Scotland or by asking your GP surgery.

- Northern Ireland uses the Health and Care (H&C) number, following the same 10-digit format. If you move from England to Northern Ireland, your NHS number typically transfers and becomes your H&C number.

Having your NHS number ready speeds up registration at a new GP practice, simplifies booking certain hospital services, and helps ensure your medical records stay correctly linked to you rather than risking mix-ups, particularly if you have a common name. It's not an emergency-only detail — keeping a note of it somewhere accessible (a notes app, alongside other important numbers) saves a bit of friction the next time you need it.

Because it's tied directly to your medical records, NHS staff will generally verify your identity before giving out your number over the phone, even to you. This isn't a sign of a problem — it's standard practice, and having a passport or driving licence on hand when you call speeds up the process.
