I live in the UK, 18 but don't know what to put down for U.S Tax Payer identification number and the Foreign tax identifying number. I don't have either the SSN or EIN so do I have to apply to get these? I don't know anything about a tax number being issued to me here, so I'm asking to see if anyone is in the same position. The fields also say 'if required' so what would happen if I submitted it without filling these two fields in?
I've submitted this question to Azoogle but what did other UK publishers put down for those two fields? 6 and 7 ?
