What should I know before I book?

Booking rules checked October 4, 2026

KTX is Korea's high-speed rail service, and visitors can reserve seats online without a Korean phone number or bank account. According to the VisitKorea train page, KTX runs at up to 330 km/h and connects Seoul with Busan, Pohang, Mokpo, Yeosu, Gangneung and Andong, with trains leaving from Seoul, Yongsan and Cheongnyangni stations.

  • Worth knowing: Booking options listed by VisitKorea include the Korail website, the KORAIL+ app, ticket kiosks, ticket offices, NAVER Train Booking and KakaoT. The app is also sold under the name Korail Talk in some guides, so search the app store for Korail.
  • A common mistake: Waiting until the day of travel. Popular Friday evening, Sunday afternoon and holiday trains can sell out, so reserve as soon as your dates are fixed.
  • Local tip: Have your passport details ready, because the English booking pages ask for them when you create an account. Settle your arrival route first with the Incheon Airport to Seoul guide.

When can I book KTX tickets?

Since October 1, 2026, Korail has sold railway tickets up to two months before departure instead of one month. The Korea Times and SBS News both report the change, and the Korea Times says it is meant to help foreign visitors plan itineraries. The old rule was one month in advance.

How do I book a KTX ticket step by step?

Create an account on the Korail English page or app, search your route, choose a train and seat class, pay by card and save the e-ticket. Screens change, so use the steps as a guide and follow the Korail ticket reservation page for the current layout.

  1. Open the booking site or app. Use the Korail global site or the Korail app in English. Korail recommends Chrome, Samsung Internet or Safari and a stable mobile network on its notice page.
  2. Sign up with your passport details. The English pages ask foreign visitors for passport details, according to guides for visitors; follow the prompts on screen.
  3. Search your trip. Enter departure and arrival stations, the date and a time, then compare departures.
  4. Choose class and seat. Pick standard or first class and your preferred seat, then confirm the fare on screen.
  5. Pay before the deadline. A reservation is held only for a limited time, and unpaid bookings are released. Use the time limit shown after you reserve.
  6. Save the e-ticket. Keep the QR code or booking number on your phone and take a screenshot as a backup.
  7. Arrive early. Find your platform, check the car and seat number and board before departure.

What if my foreign card is declined?

Korail's English booking page accepts overseas Visa, Mastercard and UnionPay, and wallet payments such as WeChat Pay and Alipay are under development. The Korea Times and SBS News report these payment details.

How much does KTX cost, and is a Korail Pass worth it?

A one-way standard-class Seoul to Busan ticket costs roughly 55,000 to 60,000 won, and a Korail Pass only pays off if you take several long rides within a few days. Published fares differ by source and by day, so confirm the exact price on the booking screen.
