I have only temporary NI numbers / Can't have a NI number as I don't work nor leave in the UK

Hi All, Sory for this long message. Just trying to give all the details. I like to get my personal contribution to National Insurance with the form PDU1. But I need to provide my NI number. I worked in the UK between 04/1996 and 12/2004 but never given a NI number. Instead on my payslips/P60/P45 I have temporary number. - I have register at HMRC and got a Government Gateway user ID, but to confirm registration it is requesting information that does not validate any NI number. - I asked with the form CA5403 to recover my NI with all details, but they replied that they can't as I don't have a NI nulber and should request one. - But to apply for a NI nulmber it says on HMRC: "You can apply for a National Insurance number if you: -live in the UK -have the right to work in the UK -are working, looking for work or have an offer to start work" I don't comply any of these points. So how do I get a NI to get my past contributions to NI. Thx in advance for your help. LB

Hi,
You will need to write to our International Caseworker section (address below) with copy of Payslip/p45/p60 from your time in the UK.
There is a process where we can get a UK NINO for individuals living abroad who have paid NI contributions in the UK previously:
