Tax identification

Hi i started using trading 212 about 7 months ago. Since i dont have a tax id, during the account creation i put " no tax id" as the app suggested. In my country you dont get a tax id until you start working somewhere so when i eventually get one will i have to submit it somehow and if yes then how do i do that?
Thanks in advance
