NI number when living abroad

Hi, my daughter is a British national and we live in France. She has been granted home fee status, tuition fee and the minimum maintenance loan by Student Finance England.

However, to be paid the maintenance loan, she needs a National Insurance number, which she obviously didn't get automatically at 16 since we live abroad and we have never claimed child benefit.

She is being asked to fill in a form giving a UK address to get her NI number. We have a lot of immediate family in England, should she give that address or wait until she is at uni, then ask for her NI number? Very confusing...

TIA
