For tickets, use this form to submit a request. A few items to note:
Requests will be accepted once ticket availability for stake members has been confirmed (normally 6-7 weeks prior to conference).
Tickets are distributed on a first-come, first-served basis -- if you've recently attended, your request may be temporarily held to allow others an opportunity.
Info for Conference Center attendees (guidelines, restrictions, parking, etc.) is available at this link.
Once all tickets have been distributed, an option may be the stand-by line - refer to this Church Newsroom article for info. You'll also want to contact the Conference Center ticket office to confirm if this will be available.
Info regarding the upcoming conference will be available on the Church Newsroom page.
