In September 2026 Seoul ended prepaid top-ups for the older 30-day Climate Card, but Seoul's official guidance says 1-, 2-, 3-, 5- and 7-day visitor passes continue. Short-term validity starts on the day of top-up, so avoid loading well before your intended first ride. Physical cards can be purchased and loaded at specified metro machines; overseas-card payment depends on supported equipment. Check route coverage and exclusions, including Seoul Bike.

Schedules, fares, inventory, booking availability and accessibility can change; recheck the operator's current notices shortly before traveling.
