With the Coronavirus cancelling pretty much everything the coming days and weeks, and some events even months out cancelling or postponed, Ticketmaster has created a page on their site to help check the status of events you may have already purchased tickets to or were planning on attending.
The page is available here and is being updated constantly.
If you have additional questions they have also created a COVID-19 Help Center to help.
This list just included information for events that tickets were sold through Ticketmaster. If your event is not on the list check back with your point or purchase or the venue. We will also do our best to keep you updated on cancellations and hopefully in the coming days we we start to see more rescheduled dates announced.
