TEDx events are independently organized. You can find TEDx events close to you through the TEDx homepage, or the events page. Simply enter in the city name, event name, or country you wish to attend an event in.
Once you find the event you wish to attend, you can go to the individual event page to find information about the venue, ticketing, and the speaker line-up. We suggest you message the organizer by sending them a message through your TED.com profile. If an event is invite-only, it is up to the organizer to allow you to attend.
Most TEDx events also have their own websites or Facebook pages through which you may be able to find more information.
If the event is still a ways off in the future, please know that all of these details might not be posted yet.
