T-money & the Seoul Subway: The Only Transit Guide You Need
Seoul subway trains run every few minutes, a ride costs about ₩1,500, and the cars are clean enough to eat off the floor (please don't). One small plastic card unlocks all of it: T-money. Subway, bus, taxi, even convenience stores take it.
Below: the three things that actually confuse first-timers — getting and charging the card (one big gotcha here), reading the subway like a local, and the handful of phrases that make buses and taxis stress-free.
Getting the card — and the cash-only gotcha
Buy a T-money at any convenience store (CU, GS25, 7-Eleven — just say "T-money card juseyo") or from the card machines inside subway stations. The card itself costs a few thousand won, then you load money onto it.
Here's the gotcha: charging is basically cash-only. The subway station charging machines take Korean won bills, not foreign cards. So hit an ATM first, then charge ₩20,000–30,000 — that covers days of riding (a subway trip is around ₩1,500). Convenience stores can also charge the card; same rule, cash.
Riding the subway like you live there
Tap in at the gate, tap out when you leave — that's the whole system. Lines are numbered and color-coded, every station has a number too (so "Hongik Univ. Station" is also just "239"), and announcements run in Korean, English, Japanese, and Chinese on major lines.
Use Naver Map or KakaoMap for routes — they show which subway car to board for the fastest transfer, real-time arrivals, and last-train times (the subway stops around midnight; taxis surge after).
Buses and taxis
Buses take T-money too — tap when boarding AND tap when getting off (skipping the exit tap can cost you the transfer discount). Transfers between subway and bus are heavily discounted if you tap within about 30 minutes.
For taxis, download Kakao T — it's Korea's Uber, shows the fare estimate, and removes the language barrier entirely because the destination is already in the app. Regular street taxis also accept T-money and cards.
Transit Korean that actually gets used
You can survive Seoul transit without a word of Korean — but these make everything smoother:
| Korean | Sounds like | Meaning |
|---|---|---|
| 티머니 카드 주세요 | timeoni kadeu juseyo | One T-money card, please (at a convenience store) |
| 충전해 주세요 | chungjeonhae juseyo | Please charge it (hand over card + cash) |
| 만 원이요 | man won-iyo | ₩10,000 worth, please |
| 이거 강남역 가요? | igeo Gangnam-yeok gayo? | Does this go to Gangnam Station? (swap any station name) |
| 여기서 내릴게요 | yeogiseo naerilgeyo | I'm getting off here (bus/taxi) |
| 잔액이 부족해요 | janaegi bujokhaeyo | "My balance is short" — what you'll say at a store, or hear (잔액이 부족합니다) from the gate when it's time to recharge |
Quick tips
- Avoid Lines 2 and 9 during rush hour (8–9am, 6–7pm) unless you enjoy being a sardine. Line 9 "express" trains skip stations — check before boarding.
- Leftover balance? Convenience stores refund small T-money balances (a small fee applies) — or keep the card; it never expires and works on your next trip.
- Priority seats (marked pink/yellow) stay empty even in packed trains — locals really don't sit there.
- Eating on the subway is legal but frowned on; phone calls are fine but kept quiet.
