Living in St Helena and working in Ascensions Island - How to get NI number

I'm living in St Helena and working in Ascensions Island, and I am a British Citizen. I have a temporary national insurance number and I would like to apply for an apprenticeship from work. How do I apply for National Insurance when I'm already working at the Island.

Hi,

If you’ve worked in the UK then please send us a copy of your P60s or payslips which show the amount of National Insurance contributions that were deducted from your salary.  Our International Team will then be able to create a full National Insurance account for you and arrange for any contributions that you may have paid to be put onto it.  They will provide you with a full National Insurance Number.

If you’ve never worked in the UK then you may apply for a National Insurance number online (via www.gov.uk) when you are in the UK.

Our postal address is:

Thank you.
