National insurance number help?

Question

im 15 and i want to start going to the gym, so i went to my local one and they told me i needed to get a national insurance number or I'm not allowed to go on the machines or anything (how unfair is that??) My mum asked if i could pretend im 16 as i looked older and they said i definitly need my national insurance number and its the same for all gyms in the country! How do i get one, my birthdays in December - Please help!!!

Answer 1

you will automatically be sent one,, you usually get it a couple of months before you are 16, so not long to wait.
