What do you need in order to add this information? 

If you give us your permission to add this extra information, we’ll use your name, address and date of birth to help the government bodies and agencies find your records. If you’re happy to add your economic or student loans records, we’d also like you to tell us your National Insurance number to help identify your information.  It would be helpful if you could have your National Insurance number to hand when the interviewer visits.

You can find this number on your national insurance number letter which is sent to you when you turn sixteen, or if you’re not sure where it is, you can also find it on your payslip, P45 or P60.
