Paying with a foreign card
Checked 2026-10-21. Rules change, so confirm on the payment screen.
Express buses (고속버스)
- KOBUS: Choose the overseas card tab (해외카드) at checkout. It takes Visa, Mastercard and JCB issued abroad and asks for your date of birth (YYMMDD).
- Klook: Sells express bus tickets in English with international cards. Routes and dates are limited, so a search may come back empty.
- Go Hanpass: App in many languages, sign-up with passport and email. You top up a won wallet with a foreign card, then pay from it. Lists express and intercity buses.
- Ticket counter at the terminal: A July 2024 government announcement described foreign cards as already accepted at express bus counters. Busy departures can sell out.
Intercity buses (시외버스)
- Ticket counter at the terminal: Foreign Visa, Mastercard, JCB and UnionPay cards were announced as accepted at all 243 intercity terminals from July 2024. Busy departures can sell out.
- Go Hanpass: App in many languages, sign-up with passport and email. You top up a won wallet with a foreign card, then pay from it. Lists express and intercity buses.
- T-money and Bustago websites: Their guides do not say whether foreign cards work. Bustago suspended foreign-card payments in October 2025 and has posted no restart notice, although a software vendor reported in October 2026 that its app accepts them again. Not confirmed.
