Hello
I would like to change my ID number to my old number. I have received a PAC code from my old network and will expire soon. I have filled the application form, however when it comes to the last name field box it says that it is invalid. I think this is because my last name is only 2 letters so it may be too short. I am not sure but I would like to know why this has happened and if this can be solved.
Many thanks
