UTR number

I submitted the registering for self assessment online form on 14/7 . After 3 weeks, I still didn’t receive the mail about UTR number. So, my question is how can I know the status of getting UTR number? And should I contact with HRMC and how? Thank you

Hi fionasms,
If you have not yet received a reply then you will need to contact HMRC to review:
Self Assessment: general enquiries
Thank you.
