I am pretty sure that this is a repost but i found the following link helpful: (found it via google)

http://www.mini2.com/forum/faq.php?f...q_tracking_usa

I didn't find it on the first page of the "how to track your mini"

 

I eventually found it the hard way too- might be nice to have a link to Mini 2 or at least the same approximate information in the NAM FAQs? I know that there's the 'How to Track Your Mini' sticky, but if it's asked often enough for the sticky, more people than me are probably trying to find it in the FAQ too?
