Numbered seats 

The customer option to receive numbered seats on the rear balcony takes place automatically during the purchase process and is a free service. When purchasing multiple tickets, the seats assigned are always consecutive when there are enough available. The two side isles of the rear balcony are not offered. AB can make no further change to the seat selection after purchase has been completed.

You can make your way to the rear balcony with permanent seats by entering the ground floor of the hall and taking the stairs near the back of the hall up to the first floor. On the balcony, you head to the left in the direction of the permanent seats. There are extra entrances to the rear balcony via the access door next to the foyer (on the left, at the front of the hall) and via the stairs at the back of the entrance hall (Agora). Until 15 minutes after the start of the concert, there is assistance provided by the stewards to guide you to your numbered seat.

The right to a seat is no longer valid in the event that, for organisational reasons, it is decided to reduce the capacity of the hall and close the rear balcony. Your ticket then automatically reverts to an unnumbered standing space. A refund is only possible in the event that the concert is cancelled or postponed.

The possession of a numbered seat gives you the opportunity to enjoy something tasty to eat in the AB Resto, in a relaxed manner and without watching the clock. You can go here for info and reservations.
