Seoul Subway Guide: Fares, Transit Passes, Apps, and Etiquette

Subway fares in the Seoul metropolitan network depend on the passenger's age, payment method, and distance traveled. Adults paying with a reloadable transit card pay a base fare of 1,400 KRW (approx. $1.00), while single-journey paper tickets cost 1,500 KRW ($1.07) plus a mandatory 500 KRW ($0.36) refundable deposit.

Fares for younger passengers are discounted:

• Teenagers (ages 13–18): 800 KRW ($0.57) using a transportation card.
• Children (ages 6–12): 500 KRW ($0.36) by card or cash ticket.

The base fare covers the first 10 kilometers of travel. Trips exceeding 10 km incur an extra 100 KRW ($0.07) surcharge for every additional 5 km traveled up to 50 km. Beyond 50 km, an extra 100 KRW applies for every 8 km. Note that certain private or regional sections, such as the Sinbundang Line or outer sections of the Airport Railroad, charge higher independent base rates or specific zone surcharges.

Travelers have multiple ticketing options depending on their schedule and itinerary length:

The standard T-money card remains the most flexible choice because it never expires and works on nationwide buses, subways, and taxis. The Climate Card offers unlimited rides within Seoul, but it excludes the Sinbundang Line, suburban Gyeonggi transit, and boarding at Incheon Airport stations.

Seoul's subway network connects the capital to Incheon and surrounding provinces through an organized, color-coded line system. Stations feature comprehensive directional signage in Korean, English, and Chinese characters, and every exit is numbered clearly to make street navigation simple.

To board and transfer smoothly:

• Tap in and tap out: Hold your card against the scanner at the turnstile gate until it beeps and shows your charged fare and remaining balance.
• Subway-to-subway transfers: Changing lines inside the station network before passing through exit turnstiles is free.
• Subway-to-bus transfers: T-money cardholders enjoy free transfer benefits when switching between subways and city buses up to 4 times within 30 minutes of tagging out (extended to 60 minutes between 21:00 and 07:00).
• Insufficient funds: If your card lacks sufficient funds to exit, use the fare adjustment machine located directly next to the exit turnstiles to top up.

Navigating Seoul's sprawling rail network is straightforward with dedicated transit apps that offer English route maps, live departure boards, and optimal transfer car recommendations.

Recommended navigation apps include:

• Seoul Subway: The official English mobile app from the transit operator, providing route planning, exit amenities, and station layout guides.
• Kakao Subway: A widely used navigation tool offering quick transfer route paths, real-time arrival counts, and station timetable information.
• Metroid Korea Subway Info: A multilingual offline route planner useful for looking up connections and travel durations without high data usage.

For broader travel guidance and multi-attraction itineraries, travelers can also consult the VISITKOREA mobile platform or Let's Korail when booking regional trains.

Seoul subway cars maintain orderly, quiet transit environments. Following a few everyday courtesy guidelines ensures a smooth ride for everyone:

• Respect designated seating: Roughly 30% of seats at the ends of train cars are reserved for the elderly, disabled passengers, and injured individuals. Bright pink seats are strictly reserved for expectant mothers and should remain vacant even during crowded hours.
• Manage bulky luggage: Take off heavy backpacks and carry them by hand, hold them on your front, or place them on the floor to prevent jostling other commuters.
• Boarding etiquette: Wait behind the yellow boarding lines marked on the platform floor. Always step aside to let arriving passengers exit fully before stepping aboard.
• Food and beverages: Avoid consuming food on trains, and refrain from bringing open, spillable drinks aboard.
