Thank you for your request.
Unfortunately we do not hold the information you require.
The Department for Work and Pensions (DWP) is responsible for the Adult National Insurance Number (NINo) allocation process and the administration of social security benefits. Her Majesty's Revenue and Customs (HMRC) are responsible for the administration of tax and National Insurance contributions and use the NINo as a reference number for doing so. Your request may be better placed with these organisations.
