CF83 Form submitted but no update showing on Gov gateway Check Progress page

Myself and my wife submitted completed CF83 forms by post (in separate envelopes) on 25 July 2023, On my wife's Gov Gateway 'Check Progress' page it shows hers as being received 2/8/23. On my Gov Gateway 'Check Progress' page it says 'I cannot see my submitted forms'. How do i find if my CF83 form has actually be received?

Hi Paul Bonner,

If you could call the National Insurance Helpline on 0300 200 3500 they will be able to make sure that we’ve received your CF83 application forms and give you an idea as to when you may receive a reply.
I can, however, advise that if you live in a European country then they are dealing with queries received in January 2023 or if you live outside of a European country then they are dealing with queries received in November 2022.

Thank you.
