Tax Year Prior to 2020: I'm currently attending a university in London and they did not enter a Federal ID number on the form needed to obtain my student tax credit. How could I get this info?

I'm filing the 1099- T form and it will not allow me to complete my return without this info. Also, I do not see the school in the list of accredited schools. However, I do not see any international school, so maybe I'm looking at the wrong list.
