Hey Guys, I figured out how to get a RUT number so you can set up an account on Ticketmaster Chile.
Simply enter the first eight digits of your passport number (don't worry about adding any remaining digits).
Then, add the number 0 as the last digit of your RUT number. If it doesn't work, try number 1. If that doesn't work, try number 2, etc. Keep trying all the way until number 9.
My passport number finally worked with number five.
The link to the presale site now takes you directly to a special U2 360 Tour page that only requests your presale code, so maybe we won't need a RUT number in the end.
