Question: how to get a national insurance number for a 15 year old?
Answer: The DWP said children who have not automatically received an NI number can apply once they have reached 16. It advised those aged 16-20 with no NI number to call the national insurance helpline on 0300 200 3500, while anyone aged over 20 should contact the national insurance application line on 0800 141 2075.
