For KTX booking for foreigners, try Korail+ first, and move to Klook or LACHA if payment fails. On September 1 this year KTX and SRT were merged, and fares fell by about 10% on average. A news report also says the booking window grows longer from October 1.
This guide covers how foreigners can buy KTX tickets without a Korean number, based on news reports, official announcements, KTO guidance and each service’s own description. Everything was checked on October 11, 2026. It’s the train and bus chapter of our [guide to Korea apps that work without a Korean phone number](internal link: hub post).
The Short Answer: Four Ways to Book
| Method | Foreign card | Best for |
|---|---|---|
| Korail+ | Yes (payment failures reported) | The default, official app |
| Klook | Yes | When Korail+ fails |
| LACHA | Yes (new app) | KTX, buses and airport rail in one app |
| Korail Pass | Pay at the seller | Several long trips |
3 Things That Changed This Year
1. KTX and SRT Merged, and Fares Dropped
According to reports, KTX and SRT began operating as a merged service on September 1. You can search and book both in the merged app, Korail Plus, and high-speed fares are about 10% lower on average than before.
For example, one report says Seoul to Busan in standard class fell from ₩59,800 to ₩54,400. Gyeongju to Seoul is reported to have dropped from ₩49,300 to ₩44,370. The cut isn’t the same percentage on every route, and some figures are given as weekday fares, so check the amount on the booking screen.
2. The Booking Window Grows to 60 Days
Reports on the announcement by the Ministry of Land, Infrastructure and Transport and Korail on September 20 say that from October 1 you can book KTX and other Korail trains 60 days before departure. It was 30 days before. It applies to all riders, not just foreigners.
I could confirm this in only some outlets. Check Korail’s official notice again before you plan around it.
3. Foreign Languages and Foreign Cards
The same reports say the foreign-language booking site supports 7 languages now, with French, German and Mongolian due by the end of the year. Overseas credit cards such as Visa, Mastercard and UnionPay work, and WeChat Pay and Alipay are said to be in development.
Foreign rail passengers from January to August numbered 6.69 million, up 68% from a year earlier, according to government data cited in the reports. Foreign ridership is clearly climbing.
Korail+: The Official App to Try First
Sign-up and Booking
Korail+ is the app that used to be Korail Talk. After the merger it’s said to let you search KTX and SRT in one place. KTO’s guide for foreign visitors released on May 29 also included Korail Talk.
On the English site, you check your booking with the email and password you used when you reserved. I couldn’t confirm from an official source whether a Korean number is required.
When Payment Gets Blocked
Google Play reviews mention foreign-card payments failing or the app freezing. If that happens, try this order:
- Pay with the same card on the computer website
- Try another card
- Switch to Klook or LACHA
Asking your card issuer to approve overseas payments in advance can help too.
Klook: An Alternative Featured in KTO’s Guide
Klook is an app featured alongside Korail Talk in KTO’s guide for foreign visitors. In a 2023 report on an agreement with KTO, Klook was said to offer express-bus tickets in 24 languages and accept foreign cards and e-wallets.
How it sells train tickets, its fees and its refund rules can differ by product. Read the cancellation terms in the product description before you buy.
LACHA: KTX, Buses and Airport Rail in One App
LACHA is an app for foreigners that appeared on the App Store in January this year. It lets you book KTX, express buses, airport rail and taxis in one place. A report from Thai media says you sign up without a Korean number or identity verification and pay with Visa, Mastercard, JCB, American Express or UnionPay.
It’s a new app without many downloads yet, though. For an important trip, don’t depend on this one app, and secure another way to book as a backup.
Korail Pass: Worth Calculating if You Ride a Lot
The Korail Pass (KR Pass) is a flat-rate pass for foreigners only. According to the seller’s description, a passport is required, and Korean citizens and some permanent residents can’t buy it. It covers standard-class seats on KTX and other major trains, but not SRT, the Airport Railroad or the subway.
It’s described as a choice of 2, 3, 4 or 5 days used within 10 days. Seat reservations are made online or at a station travel center, not at machines or kiosks. Seats can run short during Seollal, Chuseok and the year-end holidays.
I couldn’t confirm the price from the seller’s page. To work out whether it pays off, add up the regular fares for each leg you’ll ride and compare that total with the pass price. A Seoul to Busan round trip is ₩108,800 (₩54,400 × 2), so the pass gets more attractive when you take several long trips.
What About SRT?
SRT mainly departs from Suseo Station. Even after the merger, the departure station can differ from KTX trains out of Seoul or Yongsan, so check the station name when you book. After the merged app launched, the old SRT app is said to keep booking for a while but with some benefits limited.
One guide also mentions a separate English SRT booking site (etk.srail.kr). Try that if the app is hard to use.
What About Intercity Buses?
The intercity bus app T-money GO is described as having a Korean-only app store listing. For foreigners, booking express buses through Klook or LACHA is easier. Both are said to accept foreign cards.
Booking Step by Step
- Decide your date and your departure and arrival stations. Seoul, Yongsan and Suseo are different, so pick the one closest to your hotel.
- Search for trains in the app. After the merger you can reportedly see KTX and SRT together.
- Choose your seat and passengers, then pay with a foreign card. Read the refund rules before paying.
- Save your booking. A screenshot helps if the app freezes.
- Recheck the day before. Timetables and platforms can change.
KTX Booking for Foreigners: Which Method for Which Situation
One trip only? Book on Korail+. For a Seoul to Busan round trip, standard class was ₩119,600 (₩59,800 × 2) before the cut and is ₩108,800 (₩54,400 × 2) now per reports, a saving of about ₩10,800.
Several long trips? Compare the Korail Pass with the leg-by-leg total. Because fares fell, the pass may be less of a bargain than before. Check the price at the seller.
Card keeps failing? Move on to the computer site, another card, Klook, then LACHA. Don’t give up after one failure.
Plans still uncertain? Read the refund rules first. Cancellation deadlines and fees differ by platform. With a longer booking window, also think about the chance your plans will change.
5 Common Mistakes
- Booking at the last minute: weekends and holidays fill up fast. If 60-day booking applies, book early.
- Carrying only one card: foreign cards get declined, so bring two.
- Mixing up stations: Seoul Station, Yongsan and Suseo are different.
- Miscalculating the pass: don’t buy a pass before adding up the legs.
- Skipping the refund rules: deadlines and fees differ by platform.
Checklist: Your KTX Booking for Foreigners
- Sign up for Korail+ and try one foreign-card payment
- Prepare a spare card and backup apps (Klook, LACHA)
- Confirm the booking window (60 days) in Korail’s official notice
- Check whether you’re leaving from Seoul, Yongsan or Suseo
- If you ride a lot, compare Korail Pass price with your leg totals
- Check refund rules and the last train
KTX booking for foreigners is much easier than it used to be, and fares are lower. Payment is still where people get stuck most often. Since the booking window is getting longer, lock in your dates first so you don’t miss the time you want.
