It's a form of decentralisation. Your doctor doesn't need to know your tax details. The tax inspector doesn't need to know your medical history.

- arianvanp 9y agoSo it _is_ used as a secret then? I'm confused.
- codeulike 9y agoIt's about as secret as your phone number I suppose. I.e. you probably won't write it on the side of your house but you will give it to lots of people. The NHS having their own number is also to do with the NHS treating people who don't have NI numbers, and various historical reasons, eg the NHS started in the 1950s and I expect it was easier to just start a new number system than persuade the treasury to wheelbarrow over all the paper.
- jackweirdy 9y agoNHS numbers are typically more secret than NI numbers (though they needn't be necessarily) and many people don't know their NHS number at all
