Hello.
I'm going to the UK in the summer with Interrail and I'm going to get a new passport, and I'd like to buy a global pass now.
My question is, can I give my ID card number or current passport number when purchasing, even though I'm going to the UK, or am I out of luck and have to buy it after I get my new passport? Or can it be changed later? Or will an ID card be sufficient to prove my identity in the UK?
