Not receiving Company UTR

Hi I setup a company with companies house in November last year. Unfortunately the address I has used had a mistake. I have fixed this at companies house and requested the UTR several times but I have not received it. I have called HMRC but I am being told I cannot get the UTR on the phone , only by mail. But the mail request is not working. I need to apply for SEIS Advance assurance but for that I need UTR. I am completely lost in what to do. Can I get face to face appointment anywhere in UK where they will check my ID and give me my UTR? Any other hints or tips because this seems to be a roadblock for me.

Hi,

You need to apply for this using the Form here:

Ask for a copy of your Corporation Tax UTR

You need to ensure that the address on Companies House is correct as we are provided with changes from Companies House, and that you have access to this registered office address.

Thank you.
