Seoul subway, the short version

Tap in, tap out,
don't leave the station.지하철 이것만 알면 돼

The best subway in the world has one weakness: nobody explains it to visitors. Here's the page I'd text you before your first ride. Bookmark it; it works on the platform.

1. The card교통카드

₩1,550adult base fare with a card (10 km)
₩2,500~T-money card itself, any convenience store
Cashto top up at the station machine
01
Buy T-money at CU, GS25 or 7-Eleven

Say "티머니 카드 주세요" and then "만 원 충전해 주세요" (top up ₩10,000). The card works on subway, bus, taxi and at the till of every convenience store. Top-ups are cash only at station machines; many stores take card for the top-up.

02
Tourist option: the short-term Climate Card

Unlimited Seoul subway and bus for 1, 2, 3 or 5 days (about ₩5,000 / 8,000 / 10,000 / 15,000). Worth it if you ride more than four times a day. Sold at station customer-service rooms on Line 1–8 and some convenience stores; it does not cover AREX express or Shinbundang line.

03
Your phone probably won't work as a card

Apple Pay transit and most foreign Google Pay setups don't work on Seoul gates yet. Get the plastic card; it's the simplest thing in your trip.

04
Refund the balance before you fly

Convenience stores refund up to ₩20,000 of balance (₩500 fee) but not the card price. Or keep the card: it's the best ₩2,500 souvenir and still works next trip.

2. Five rules이것만 지키면 됨

01
Tap in AND tap out

Forget to tap out and the next tap charges you the maximum fare and a confused look from the gate. Buses too: tap when you get off and transfers within 30 minutes are free.

02
Transferring? Follow the signs, don't exit

Changing lines happens inside the gates ("환승" signs, colour-coded). If you accidentally go through an exit gate, you'll pay again. Walk the corridor; some are long (Express Bus Terminal, Jongno 3-ga).

03
The pink seats and the end seats are not yours

Pink seats are for pregnant women even when empty. The seats at each end of the car are for the elderly; sit there and someone's grandmother will tell you about it. Everything else is fair game.

04
Quiet car, always

No phone calls, no speakerphone, no loud groups. Eating is technically fine but nobody does it. Backpack on your front in rush hour. Let people off before you get on; Koreans queue at the door markings.

05
Exit numbers are the address

Every meeting point in Seoul is "station name + exit number". The planner and the taxi card on this site use them. Exits are numbered clockwise; the yellow signs inside the station list what's near each one.

3. The lines that matter이 노선만 알면 됨

2
Line 2 · the green loop

Circles the city; you'll live on it. Hongdae, City Hall, Euljiro, Dongdaemun, Konkuk, Seongsu, Jamsil, Gangnam, Sinchon.

Watch for: Seongsu and Sindorim have short branch lines; check the destination on the train.
3
Line 3 · orange, old town to Gangnam

Gyeongbokgung, Anguk (Bukchon/Insadong), Jongno 3-ga, Express Bus Terminal, Sinsa (Garosu-gil), Apgujeong.

4

1
Line 1 · dark blue, the oldest

Seoul Station, City Hall, Jonggak, Jongno 3-ga, Dongdaemun. Trains run far out of the city; check the destination board.

5
Line 5 · purple, river and parks

6

Itaewon, Hangangjin (Hannam), Noksapyeong (HBC), World Cup Stadium (Haneul Park).

9
Line 9 · gold, with an express

A
AREX · the airport line

Exits are checked against the station maps in October 2026. Stations change exits during construction; the yellow boards inside always win.

5. Airport, both ways공항 가는 법

AREX all-stopT-money, ~₩4,750 to Hongdae (55 min) or Seoul Station (65 min). Stops at Hongdae. Best for most people.
AREX ExpressNonstop to Seoul Station, 43 min, ~₩11,000 (cheaper online, counts as a separate ticket, not T-money).
Limousine bus₩17,000–18,000, door-to-door to Myeongdong / Gangnam hotels. Best with big luggage. Stops at both terminals.
Late nightLast AREX from Incheon ≈ 23:30; after that it's the N6001/N6002 night bus to Seoul Station or a taxi (₩70,000+ with night rate).

Going back: at Seoul Station you can check in bags for some airlines (Korean Air, Asiana) at the City Airport Terminal before taking the Express. Check your airline; it's a quiet luxury.

6. Times첫차·막차

~05:30first trains
~24:00last trains leave the centre (earlier at the ends of lines)
07:30–09:00
18:00–19:30
rush, avoid Line 2 and 9

There is no night subway in Seoul. After midnight: night buses (N-numbered, ~₩2,500) or taxis. Check the last train in Naver Map; the app shows "막차" times per direction and will route you home before it leaves.

7. Say it이 말만 하면 돼

Know the subway, now use it: let me plan your day around the right stations, or get the taxi card for the ride home.
