# Arriving in Seoul: AREX, the International Taxi, and Paying for the Subway with a Foreign Card > How to get from Incheon into Seoul by the airport railroad, bus or the International Taxi for foreign visitors, how to buy subway tickets with a foreign card, and the 1330 travel hotline. - Checked against the official source: 2026-11-04 - Official source: [Incheon International Airport, taxis](https://www.airport.kr/ap_en/1515/subview.do) - Web page: https://travelsmarterasia.com/guides/seoul-airport-to-city/ - Publisher: Travel Smarter Asia (https://travelsmarterasia.com/about/) - Some links below are affiliate links (the /go/ addresses).

Check whether you need [a K-ETA](https://travelsmarterasia.com/guides/korea-k-eta/) before you board, and what [Korea customs](https://travelsmarterasia.com/guides/korea-customs-arrival/) allows on arrival. The airport itself advises allowing 1 to 2 hours for immigration after your flight arrives before you plan onward transport. ![Infographic, step 1 of 4. Landing in Seoul? Allow time for immigration first. Incheon to Seoul: 1, the AREX general train to Seoul Station in 66 minutes, and a direct express runs too. 2, airport bus: Terminal 1 ticket booths are next to exits 4 and 9. 3, International Taxi for foreign nationals, booked on 1644-2255.

Illustration by Travel Smarter Asia.") ## AREX: the airport railroad The Airport Railroad (AREX) runs from Incheon to Seoul Station, where you can change to the KTX and subway lines 1 and 4. Incheon Airport's page puts the general train at 66 minutes to Seoul Station. AREX also runs a direct express train. The airport sends fare and timetable questions to the airport railroad hotline, 1599-7788, and its website. We could not read the AREX fare table on 4 November 2026, so we publish no fares. ## Airport buses At Terminal 1, bus tickets are sold at "ticket booths located inside the terminal (next to exits 4 and 9)". For Seoul city buses, the airport points to the Dasan Call Center on 02-120. ## The International Taxi Incheon Airport runs International Taxis "For Foreign Nationals Only", booked on 1644-2255. For trips into Seoul, the airport says a "flat fare applies", but its page does not give the amount, so ask when you book. Ordinary taxis add a night surcharge: "approximately 20% to 40%" between 22:00 and 04:00. ![Infographic, step 2 of 4. The International Taxi for foreign visitors.

Illustration by Travel Smarter Asia.") ## Paying for the subway with a foreign card Since 17 March 2026, 440 new ticket vending machines at 273 stations on Seoul subway lines 1 to 8 accept "credit and debit cards issued overseas for fare payment", the government's Korea.net reports, naming Visa, Mastercard, Kakao Pay and Naver Pay. That is at the ticket machine. We found no official source saying you can tap a foreign bank card at the subway gate itself, so buy a ticket or a stored-value card at the machine first. ![Infographic, step 3 of 4. Subway tickets: foreign cards work at the machines. Since 17 March 2026, 440 ticket machines at 273 stations on lines 1 to 8 take overseas credit and debit cards, Visa and Mastercard, plus Kakao Pay and Naver Pay. At the machine, not the gate: no official source says you can tap a foreign card at the gate.](https://travelsmarterasia.com/images/seoul-airport-to-city-infographic-3.png "Step 3 of 4.

VisitKorea says it can also be reached by online voice call over Wi-Fi and by messenger apps, including KakaoTalk, Line and WhatsApp. We could not open the police and fire agencies' English pages on 4 November 2026, so we do not list their numbers here. Save 1330 before you land. Most of that help, and the AREX fare tables, sit behind an app or a website, so a connection on landing matters. With [Saily installed before you fly](https://travelsmarterasia.com/go/saily), your phone has data in the arrivals hall. If Seoul is one stop of several, [keep the same Saily profile and add a country](https://travelsmarterasia.com/go/saily). ![Infographic, step 4 of 4.
