How to find your parent's NHS number (and what to do if you can't)

# How to Find Your Parent's NHS Number (and What to Do If You Can't)

The phone is ringing in a hospital corridor, or a form needs filling in for a GP referral, and someone asks: "What's Mum's NHS number?" Most of us have never needed to know it. This guide covers where it is usually written down, what has changed about looking it up, what to do when your parent can't tell you, and how to keep it somewhere you can find it next time.

It describes how things work in England; the other UK nations have their own systems, mentioned near the end.

What an NHS number is

An NHS number is a 10-digit number, usually written in groups of three, three and four (for example 999 123 4567). It is unique to each person and helps healthcare staff match the right details to the right records. If your parent has had NHS care in England, Wales or the Isle of Man, they should already have one, and it normally stays the same for life.

The reassuring part: according to NHS.UK, you do not need to know the number to use NHS services. Nobody should turn your parent away for not having it to hand. But knowing it makes calls, referrals, prescriptions and discharge paperwork move faster.

The first thing to know: the online lookup has gone

Many people search for "find my NHS number" expecting a quick online lookup. NHS.UK now states that its "Find your NHS number" service has been discontinued, so there is no public website where you can type in a parent's details and get the number back. That is also good news for privacy, but it means you need to use the routes below.

Where to look, from easiest to hardest

1. Letters and documents

Check anything your parent has received from the NHS. The number commonly appears on:

• hospital appointment and referral letters
• test result letters
• prescriptions and repeat prescription slips
• discharge summaries and clinic letters
• vaccination or screening invitations

If your parent keeps their paperwork in a drawer or folder, ten minutes there is usually the fastest route. Photograph or copy the page with the number, and keep the original where it was.

2. Their NHS App or NHS website login

If your parent uses the NHS App, they can open Profile, and the number is shown under their name and date of birth. If they are happy to, sit with them and let them show you. NHS.UK also notes the number may appear in some GP online services.

One thing that catches families out: if you manage a parent's services through the NHS App, the app does not currently let you view their NHS number from your own account. The NHS App page says you cannot see it there, so look at their own login or letters instead.

3. Their GP surgery

NHS England says that if letters and online options do not work, you can ask the GP surgery. There are two catches:

• The surgery can usually only give the number to a patient registered with them.
• They may ask for photo ID such as a passport or driving licence, to protect privacy.

If you are asking for your parent, expect the surgery to want your parent's agreement, or a clear arrangement that lets you act for them. Phone in together if you can, so your parent can confirm who you are.

What if your parent can't tell you, or can't find it?

Some situations are harder: a parent in hospital, with memory problems, or living far away.

In an emergency or on admission. Hospital staff can identify your parent by name, date of birth and address, and they can find the NHS number themselves. Do not hold up care because you don't have it. Give the clinicians the details you do know and say what's missing.

Ask the surgery about family and carer access. NHS.UK explains that "proxy access" (also called family and carer access) lets a trusted person use a patient's online health services. For an adult, access is usually granted when the person asks for it or understands and agrees to it. Adults aged 16 and over are presumed able to give consent. If an adult lacks capacity, for example because of dementia, the surgery may decide whether access is in their best interests. To apply you contact the surgery of the person you want to help; you may both need to fill in a form and show photo ID, and the surgery decides what access is appropriate. This is worth asking about early, before a crisis. It is not a lookup for the number itself, but it can give you a legitimate route to appointments, prescriptions and information.

Legal authority. A lasting power of attorney for health and welfare, or similar arrangement, is a separate matter. Our UK message-in-a-bottle and LPA checklist explains what to have in place and why it matters before you need it.

Don't guess or use a number you found online. NHS numbers have a built-in check digit, and sample numbers appear in guides. Writing down a wrong number can cause confusion in records. Only copy a number from your parent's own paperwork or app.

Is the NHS number the same as a hospital number or National Insurance number?

No on both counts. A hospital number (sometimes called a case note or MRN number) is a local record number used by one hospital. The NHS number is the single identifier used across NHS services. Neither is the same as a National Insurance number, which is a tax and benefits identifier. When a form asks for a number, check which one it wants.

Scotland, Wales and Northern Ireland

Scotland uses a 10-digit CHI (Community Health Index) number. Public Health Scotland describes it as the identifier on Scotland's CHI register, allocated when a person is first registered, and used on clinical communications. If your parent lives in Scotland, look for it on health letters and ask their GP practice or health board. NHS.UK's pages are written for England, and they do not describe the routes in the other nations, so if your parent lives in Wales or Northern Ireland, ask their GP surgery how it works locally.

Keep it where you can find it next time

Once you have the number, the best thing you can do is stop having to hunt for it again. Put it with the other details someone will need in a hurry:

• full name and date of birth
• NHS number (or CHI number)
• GP surgery name and phone number
• current medicines and allergies, with the date the list was last checked
• main diagnoses and the hospital or clinic they attend
• who to call, and who has permission to speak for them

Our guide to a medical information sheet for a parent shows what to put on one page, and the hospital discharge checklist lists the paperwork to ask for when a parent comes home. If you are organising everything for the first time, start with how to organize your parent's medical information and the wider documents checklist for aging parents.

Treat the number like any other personal health detail: don't post it publicly, and share it only with people who need it. ParentFile is an organisation tool for exactly this kind of detail. It helps a family keep a parent's key information on one page: for a parent in the UK, the sheet has a place for the NHS number and the GP surgery, and it checks that the 10 digits pass the NHS check-digit test, which catches most typing mistakes. It is not a medical or legal service, and it does not look numbers up for you. You can start with our free one-page ER sheet.

A short checklist

• Check recent NHS letters, prescriptions and discharge papers for the 10-digit number
• Ask your parent to show you the number in their NHS App profile, if they use it
• If neither works, phone their GP surgery together and expect ID checks
• Ask the surgery about family and carer (proxy) access
• Copy the number only from your parent's own paperwork or app
• Write it on a medical information sheet with GP, medicines and contacts
• Note which nation's system applies (England, Scotland, Wales, Northern Ireland)
• Keep one copy at home and one where the family can reach it
