Did a dummy run last week on Liverpool tickets. Go onto Napoli website, apply for ticket, page come up asking for your details, name etc, put down EE11 for medical, then scroll down menu for country of birth, sure I remember the UK was not on list however it accepted my UK address and post code, it also has UK dialing code for mobile, then it asked for Fedelity number, apply for that through ticket one, ( From what I can gather the card is for all venues across Italy ) Ticket one then give you a membership number which you put in original format of the form. Could be an issue from where you were born, I was born in India which was on the drop down country’s and sailed through all, will go for 4 tickets as young lad going as well, if I get these two will apply for another two for anyone that requires them, 1st come and all that. Cheers.
