How do I get a Class 2 National Insurance reference number to pay online

Posted Fri, 28 Jul 2023 11:06:25 GMT by
Hi I have four years I need to pay according to my NI record. When I try to pay I need an 18 digit NI number (not my regular NI number). How to obtain this number and the amount I need to pay? Thanks in advance!

Hi,
You will need to contact the National Insurance helpline to obtain your 18 digit reference number and also details of how much you need to pay.
You can contact them on 0300 200 3500, lines are open from 8am to 6pm Monday to Friday.
Thank you.
