Due to the number of problems that have arisen from the use of foreign cards in certain transactions, there are certain limitations that are in place regarding the use of foreign cards.
Foreign cards are only permitted a certain number of transactions per day and per month, and have a total purchasing limit per month.
The frequency of use limit is 3 transactions per day, 15 transactions per month (including cancellations). The total purchasing limit is 2,000,000 won per month for performances and 50,000 won per month for movies (including cancellations). If you are no longer able to reserve or cancel your tickets, most likely it is because you have exceeded the limitations in your foreign card use.
