Hello I sent a Form CF83 and received a reply re which years I could make voluntary NI payments and how much each year would cost. It did not say if they are class 2 or 3 but looking at the figures it appears there is a mixture. I would like to pay all the lower (classe 2) value years. It mentioned a link to make payments but the page told me I needed an 18 digit code which has not been provided. I tried to make one up using my NInumberCINameIntial but it was not accepted. Can I make a bank transfer ? If I make a bank transfer, how do I specify which years I wish the funds to contribute towards? Thank you
