Hi,
We should be able to resolve this quickly over the telephone if you contact our National Insurance team.
National Insurance: general enquiries
If you prefer, you can write to the following address:
HM Revenue and Customs,
Individual Caseworker Section,

However, the area that would deal with your written enquiry are currently dealing with work received on 21 January 2024.
Thank you.
