Choosing the duration
Seoul City's page updated 12 October 2026 lists 1 day at KRW 5,000, 2 days at 8,000, 3 days at 10,000, 5 days at 15,000 and 7 days at 20,000. A separately verified youth seven-day pass is KRW 13,000 for eligible ages 13–18. A physical card costs an additional KRW 3,000.
Your top-up day is day one
For short-term passes, validity starts on the day you load the pass. Loading a day early can waste a travel day. Check service dates and the first-train (04:00) to last-train validity rule.
Not every train and bus is covered
The pass principally covers eligible Seoul subway stations and Seoul-licensed local buses. Shinbundang Line, GTX, metropolitan and airport buses, and non-Seoul-licensed buses are excluded. Short-term passes do not include public bikes or Hangang Bus. Airport Railroad trips have an exception for alighting at Incheon Airport T1/T2 after boarding within the valid area, not boarding there. Exiting at non-covered stations may require additional payment.
Purchase and refund tips
Seoul lists mobile Tmoney or Samsung Wallet on Android 12+, and a physical card for iPhone users. Register the physical card: unregistered cards cannot be refunded. Refunds must be requested within the pass period, subject to deductions; after expiry they are normally unavailable. Confirm the latest retail and payment arrangements before buying.
