For visitors taking several subway or Seoul-licensed bus trips a day, the short-term Climate Card can simplify fares. The key 2026 distinction is this: Seoul's resident-focused 30-day product changed on September 1, while physical Climate Cards can still be loaded with 1-, 2-, 3-, 5-, or 7-day visitor passes.

The Fast Answer
The pass costs KRW 5,000 for 1 day, KRW 8,000 for 2 days, KRW 10,000 for 3 days, KRW 15,000 for 5 days, or KRW 20,000 for 7 days. A physical card costs KRW 3,000 separately. Validity starts on the loading day, so it cannot be loaded early for a later start.
It does not cover every service on a Seoul-area map. Sinbundang Line, GTX, intercity and airport buses, non-Seoul-licensed buses, and subway travel outside the eligible range can be excluded.
What Changed in 2026?
Seoul announced that internationally issued credit and debit cards became usable at 440 new vending machines in 273 stations on Lines 1-8 from March 17, 2026. An average service fee of about 3.7% applies.
The current policy page says the 30-day prepaid Climate Card could be recharged only through August 31, 2026, with the resident-focused Climate Pass launched September 1. Existing physical cards can still receive short-term passes. Ignore old tutorials presenting the 30-day product as the default tourist choice.
Which Pass Fits Your Trip?
- 1 day — KRW 5,000: concentrated sightseeing through the last eligible service that calendar day.
- 2 days — KRW 8,000: a compact weekend within Seoul.
- 3 days — KRW 10,000: a city break with frequent transit.
- 5 days — KRW 15,000: a longer Seoul-focused itinerary.
- 7 days — KRW 20,000: a full week when most rides remain inside coverage.
A one-day pass loaded late at night is not a rolling 24-hour product.
How to Buy and Activate a Physical Card
- Find a participating new vending machine or indicated convenience-store point.
- Buy the physical card for KRW 3,000.
- Load a short-term pass when ready to begin.
- At supported machines, pay with an internationally issued card; expect the stated fee and keep an alternative method.
- Tap when entering and exiting buses and subway gates.

Coverage: Where Travelers Make Mistakes
Eligible service includes Seoul-based subway sections and Seoul-licensed city and town buses, including night buses. Seoul says riders may exit at Incheon Airport Terminals 1 or 2 after boarding within the eligible range, but may not board at those airport stations with the pass. Airport buses are excluded.
Entering inside the eligible subway area does not guarantee an outside-range destination is covered. Seoul gives Jongno 3-ga to Indeogwon as an example where staff collect the out-of-range fare. A Seoul-licensed bus can remain eligible outside the city boundary.

Climate Card or Pay Per Ride?
Use the pass when convenience and frequent eligible rides outweigh the card cost. Pay per ride when you expect fewer trips, day trips outside Seoul, airport or intercity buses, or maximum flexibility.
Compare pass price + KRW 3,000 card + international-card fee with fares for rides you realistically plan. Do not count excluded trips as savings.
Tap-Out, Refund, and Registration Cautions
Seoul instructs users to tap on and off. Repeated failure to tap out can trigger a 24-hour suspension. Refunds must be requested before expiration; the formula is charged amount minus transit use minus KRW 500. Unregistered physical cards have limits, including unavailable refunds and Seoul Bike access. A foreign visitor without a Korean bank account may need to visit Tmoney headquarters for a refund.
Short-term passes do not include Ttareungi Seoul Bike. Old articles often mix 30-day benefits with visitor passes.
