I think I understand what you’re talking about...I’ve being trying to subscribe to some newsletters and almost all Internet forms had a RUT mandatory field.
When I travelled to Chile and I was asked for a RUT, I said I didn’t have one and they usually would be ok with my passport number. BUT there’s no way to use a foreign passport number for a form on the Internet...
So, here’s what I’ve done: a RUT has 8 digits+ verifying digit. Something like 12.345.678-9. I’ve used my real passport number for the first 8 digits (12.345.678). Then I had to calculate the last one. This is the result of a mathematical algorithm. Here’s how to calculate it: http://lists.umanitoba.ca/pipermail/epi ... 01132.html
And...it worked! The website won’t verify the RUT but it will verify that there’s a link between the first 8 and the last digit. Now, this number has no real meaning or value. You cannot use this for legal procedures.
But it will help you to fill those forms and get to the information you need. When you'll be in Chile, you'll have your real RUT.
