Each section has a varying number of rows and seats per row. If you already have tickets, find your seats for row and seat numbers.
As you face the stage from your seats, lower number seats are on your right.
At some venues, a ticket seller must put in a row number or letter when selling their tickets. Because there are no row numbers when the floor is general admission, some sellers will put in GA0, 1, etc. when listing GA tickets. For most shows - including Twenty One Pilots - this is merely a placeholder. We recommend purchasing the GA Floor tickets with the lowest price.
