UTR not received

My wife and me have submitted for the application for UTR on Sept 2022. My wife got the UTR letter and submitted the online tax return successfully. I think I have the same letter at that time. However, I am wrong. . When I check my personal tax account on January 2024, UTR was not found in my account. Then I re-submit that application for early January 2024. Neither UTR letter received nor UTR shown on my personal tax account. How can I submit my self assessment? Please advise.

Hi,
You can only submit your Self Assessment if you have a UTR number allocated.
If you orginally registered back in Septmeber 2022 then a UTR should have been allocated.
If you contact HMRC we can check this for you:
Self Assessment: general enquiries
Thankyou.
