  • 18 digit reference number

    I applied to HMRC for information on making additional voluntary NI contributions, and received the information I wanted. I now want to make a payment. My letter tells me to send a cheque by post, but I understand that due to Covid this is not currently accepted. I'm happy to pay by bank transfer, but I believe I need an 18 digit reference number, and this is not identified anywhere in the letter. Can you tell me how to track it down, please, or how else I can make the payment? Thank you
