How to Buy KTX Tickets in South Korea

KTX tickets are easiest to buy through the official KORAIL website before your trip. You can also use the KORAIL Talk mobile app, a ticket machine, or a staffed counter at a KORAIL railway station. Reservations normally open at 07:00 Korean Standard Time one month before departure.

The booking rules and service information below were verified on June 9, 2026. Train times, fares, refund fees, and holiday reservation procedures can change, so confirm them through KORAIL when booking.

Quick answer

For most visitors, the simplest method is:

1. Open the official KORAIL English reservation page.
2. Enter your stations, date, and passenger count.
3. Choose a KTX service and seat class.
4. Enter the requested passenger and contact details carefully.
5. Pay by credit card.
6. Open or download the issued ticket before going to the station.

Where to buy KTX tickets

KORAIL lists four main sales channels: its website, the KORAIL Talk app, station ticket machines, and staffed railway-station counters. Tickets are not sold at ordinary Seoul subway stations. These purchase channels were confirmed through the official KTX ticketing guide on June 9, 2026.

Official KORAIL website

The English reservation page is generally the most convenient option for international travelers. It allows you to search schedules, compare available trains, and buy a ticket without joining KORAIL membership.

When booking as a non-member, record the email address and password exactly as entered. KORAIL notes that passwords and email addresses are case-sensitive when retrieving a reservation.

Avoid relying on similarly named third-party booking sites. In an official warning about unauthorized ticket websites, KORAIL said that unofficial sellers may charge substantial markups and may create a risk of invalid tickets. The safest starting point is the korail.com domain.

KORAIL Talk app

KORAIL Talk is KORAIL's official mobile application. It is useful if you expect to book, change, or refund tickets while traveling in Korea.

Check the developer name and branding carefully when downloading it from an app store. App availability, supported languages, and payment behavior can vary by device and app version. If an international card is rejected, try the official website or buy at a station rather than repeatedly submitting the same payment.

Ticket machines and station counters

Major KORAIL stations have ticket machines and staffed counters. Machines may provide a language-selection option, while a counter is usually easier when you have an unusual itinerary, need accessibility assistance, or are unsure which station to use.

At the counter, show the staff:

• Your departure station
• Your destination
• Travel date
• Preferred departure time
• Number and ages of passengers
• Standard or first class

Writing the station names and date on your phone reduces the chance of a misunderstanding. Payment methods available at a particular machine or counter can vary, so carry a physical payment card and some KRW as a backup.

When KTX tickets go on sale

As verified on June 9, 2026, ordinary KTX tickets normally become available at 07:00 one month before the departure date. KORAIL lists the following general sales deadlines:

These are sales deadlines, not recommended arrival times. Buying a ticket immediately before departure leaves little time to find the platform or correct carriage.

Holiday periods can use completely different reservation procedures. For Seollal, or Lunar New Year, and Chuseok, or Korean harvest festival, KORAIL may announce designated booking dates, route-specific sales windows, payment deadlines, and limits on station sales. Ordinary one-month booking rules may therefore not apply.

Check the KORAIL English notices page before attempting to reserve travel around a major Korean holiday. Popular Friday-evening, Sunday-evening, and holiday services can sell out even outside the special reservation period.

How to book on the KORAIL website

Step 1: Search for the correct stations

Go to the official ticket reservation page. Enter the departure station, arrival station, travel date, and number of passengers.

Do not assume that every train for a city uses the same station. Seoul, Yongsan, Cheongnyangni, Gwangmyeong, and Suseo are separate stations. Busan and Bujeon are also different. Check the station on your ticket against your accommodation and local transport route.

Suseo is particularly important: it is associated mainly with SRT services, although limited cross-operation involving KTX and SRT began in 2026. Search the actual journey rather than assuming that a ticket marked KTX always leaves from Seoul Station.

Step 2: Review the search results

The results show the train type, departure and arrival times, journey duration, and available classes. Select KTX rather than a slower ITX or Mugunghwa service if high-speed rail is your intention.

A direct train is normally easier with luggage. If the itinerary includes a transfer, allow enough time to leave one train, find the departure board, and reach the next platform.

Step 3: Choose standard or first class

Standard class is sufficient for most trips. First class provides a different seating layout and additional space, but the exact facilities depend on the KTX train type.

The fare shown in the live booking results is the figure to trust. KTX fares depend on the route, class, service, and any applicable discount. Because fares can change, this guide does not substitute a fixed price for KORAIL's current booking result.

Step 4: Enter passenger and contact details

Enter names and contact information accurately. For a non-member reservation, keep a record of the email address and password used during checkout. You will need them to retrieve the ticket through the MY TICKET section.

Select the correct passenger category. According to the official KORAIL ticket FAQ, children aged 6 through 12 receive a 50% discount. Children under 6 may travel without a separate fare when no seat is required, subject to KORAIL's accompanying-child limits. If you want a dedicated seat for a young child, include the child and seat in the booking.

Passenger-age rules were verified on June 9, 2026. Confirm the displayed fare before payment, particularly when a child will turn six or thirteen near the travel date.

Step 5: Pay and issue the ticket

KORAIL's English guide states that payment can be made by credit card. Card acceptance may depend on the issuer, authentication method, and booking channel.

After payment, make sure the transaction produces an actual issued ticket. A search result, reservation attempt, or card authorization screen is not proof that you have a seat.

Your ticket should show at least:

• Travel date
• Train number
• Departure and arrival stations
• Departure time
• Carriage number
• Seat number

Step 6: Retrieve the ticket before departure

Use MY TICKET on the KORAIL website and enter the same email address and password used for purchase. Open the ticket while you have a reliable connection and keep the reservation details accessible.

A digital ticket does not normally need to be exchanged at a station counter. However, if the ticket cannot be displayed or the details are incomplete, visit a counter before boarding.

Choosing the right ticket and train

KTX is not the same as SRT

KTX is operated through KORAIL's ticketing system. SRT has traditionally used a separate operator and reservation system. Korea began trial cross-operation between selected KTX and SRT services in 2026, which means the train brand and station pattern may not always follow older assumptions.

The practical rule is simple: follow the operator, train number, and departure station printed on your issued ticket. Do not go to Seoul Station when the ticket says Suseo, or assume that a KORAIL Pass covers an SRT-branded service.

Ordinary ticket or KORAIL Pass?

A KORAIL Pass is intended for eligible foreign visitors making several intercity journeys. As verified on June 9, 2026, the official KORAIL Pass guide listed adult prices from KRW 131,000 for a two-day select pass to KRW 275,000 for a five-day select pass.

A pass is not automatically cheaper. Compare its price with the live total for your individual tickets. The pass does not include SRT, metropolitan subway services, or certain temporary tourist trains.

Buying a pass also does not automatically reserve a seat. You must make separate seat reservations through MY TICKET. KORAIL requires pass users to carry the valid pass and passport, and its official conditions state that a screenshot is not accepted as a valid pass.

Refunds and changes

Before departure, online and mobile tickets can generally be refunded through the same KORAIL channel. After the departure time has passed, KORAIL instructs passengers to request a refund at a KORAIL station counter. No refund request is accepted after the train's scheduled arrival time.

Refund penalties depend on when you cancel and whether you are traveling Monday through Thursday or during a Friday-to-Sunday, public-holiday, or designated peak period. The current fee table is published in the official KORAIL ticketing guide. These rules were verified on June 9, 2026, but check the displayed refund amount before confirming a cancellation.

KORAIL does not provide a simple online edit for every change. In practice, changing the date, time, route, or class may require you to refund the original ticket and buy another one. Secure the replacement first when availability is limited, provided you are comfortable temporarily paying for both tickets.

Do not board an earlier or later KTX merely because it follows the same route. Your ticket is for the specified train and seat.

At the station and on the train

Arrive with enough time to check the departure board and locate the platform. Around 15 to 20 minutes is reasonable at a familiar station; allow more time at a large or unfamiliar station, when traveling with children, or when carrying luggage.

The departure board may display destinations and intermediate stations in Korean and English. Match the train number and departure time, not only the destination.

On the platform, carriage-position signs indicate where each car should stop. Board the carriage shown on your ticket and use the assigned seat. Keep the ticket available throughout the journey in case staff request it.

KTX trains do not have a dining car, according to KORAIL's official onboard-amenities information. Buy a meal before boarding if needed. Some trains have vending machines, but availability should not be treated as guaranteed for a particular journey.

Common mistakes to avoid

• Using an unofficial reseller: Start at korail.com and check the total price before paying.
• Selecting the wrong Seoul-area station: Seoul, Yongsan, Cheongnyangni, Gwangmyeong, and Suseo are not interchangeable.
• Confusing KTX with SRT: Check the operator, train number, and departure station.
• Waiting until the weekend: Popular services may already be sold out.
• Forgetting non-member login details: Preserve the exact email address and case-sensitive password used during booking.
• Assuming a pass includes a seat: KORAIL Pass holders must reserve seats separately.
• Boarding a different departure: An ordinary ticket does not permit travel on any KTX running along the route.
• Canceling too late: Refund fees rise as departure approaches, and post-departure refunds require a station visit.
• Relying only on a screenshot: Keep access to the actual ticket or pass page, especially when using a KORAIL Pass.

Accessibility and luggage

Travelers requiring wheelchair space, boarding assistance, or other accommodations should contact KORAIL or visit a staffed counter in advance. Available spaces and boarding procedures depend on the train and station. The English-language KORAIL Customer Service Center was listed as +82-1599-7777, operating daily from 08:00 to 20:00, when verified on June 9, 2026. Confirm current assistance arrangements directly with KORAIL rather than relying on a general booking note.

KTX passengers normally carry their own luggage onto the train. Storage space is limited, particularly for large suitcases. Keep valuables with you, arrive early enough to store bags without blocking the aisle, and avoid bringing luggage that you cannot lift or manage independently.

What to check before you go

• Confirm the exact departure station, not just the city.
• Check the travel date, departure time, and train number.
• Confirm that payment completed and a ticket was issued.
• Open the ticket before leaving reliable Wi-Fi or mobile data.
• Check the carriage and seat numbers.
• Review KORAIL notices if traveling around Seollal or Chuseok.
• Allow extra station time for luggage, children, transfers, or accessibility needs.
• Check the latest schedule on the day of travel for disruptions or operating changes.

FAQ

Can I buy a KTX ticket after arriving in Korea?

Yes. Use the KORAIL Talk app, a ticket machine, or a staffed KORAIL station counter. Same-day seats may be limited on busy routes.

Do I need a Korean phone number?

The English KORAIL website provides a non-member booking route using contact and reservation-retrieval details. Requirements may differ in the Korean app or member system, so the English website is usually the clearer starting point for short-term visitors.

Can I use a foreign credit card?

KORAIL officially states that credit-card payment is available, but its public English guide does not guarantee acceptance of every foreign-issued card. If payment fails, try a different card, the official app, or a station counter.

Can I buy KTX tickets at a subway station?

No. KORAIL specifically says station sales are available at railway stations, excluding subway stations.

Should I print my ticket?

An issued mobile or web ticket can generally be used without visiting a counter. Keep the complete ticket accessible. KORAIL Pass holders should follow the pass-specific document rules and carry their passport.

What if the train is sold out?

Search nearby departure times and verify whether another appropriate station serves your route. Do not buy a ticket to a different station until you have checked the additional local-transport time and cost. Pass holders may have standing-travel options under KORAIL's pass conditions, but ordinary passengers should follow the availability shown during booking.
