HI there. I am trying to get a UTR and no matter what I do I fail the identity check. I suspect that the name I am registered with HMRC is different from the name on passport and driving license Buti can't seem to find a place where I can access all my information. I tried to change the name but to change the name you have to pass the identity check and it fails . I am running in circles because everything depends on the identity check and that is what is failing so I pretty much cannot get my urgently needed UTR. Can anyone please advise ? I have tried ringing 03002003300 but after a load of recordings the number hangs up. All recommendation is that I can do it all online BUT if I fail the identity check I can't do anything. Is there an address I can write to? Please do advice . I am running out of options! Thanks.
