National Insurance Number process

Hi, I applied a NINO from September 2023, but never received any response from your department and I call 0800, the staff told me over 6 week, cannot trace my reference number, then, advise me to filled up CA5403 form by post. And post it on December, so now when can I receive my NINO?

Hi Lavina,
It is not clear from your enquiry if you actually have a National Insurance number (NINO) or not.
In the first part of your enquiry you say you applied for a NINO in September 2023 but didn’t get a response from ‘us’.
HMRC do not issue NINO’s.
Applications for NINO’s are dealt with by the Department of Work and Pensions (DWP) and it is them who issue NINO.'s
Their telephone number is 0800 141 2079.
We assume this is the ‘0800’ number that you refer too.
The process to issue a NINO should not take more than 8 weeks.
If you called HMRC and we were unable to trace a NINO for you, this may mean that one has not been issued to you or it may mean that we need more information to trace it.
This information would be requested on form CA5403.
You say you sent this form to us in December, the usual processing time for this form is 7 working days.
If you have not received a reply, we suggest you call both DWP on 0800 141 2079 and also the NI helpline on 0300 200 3500.
Thank you.
