Getting Around Korea: T-money, Subway & Bus for Newcomers
Public transportation is one of the easiest parts of life in Korea: one rechargeable card covers the subway, city buses, and most taxis nationwide, transfers between them are discounted, and services run frequently and on time. This guide covers what newcomers actually need in the first week — getting a T-money (티머니) card, topping it up, understanding how transfers work, and the small etiquette rules locals notice.
What T-money is and where to buy it
T-money (티머니) is Korea's standard rechargeable transit card: you tap it on a reader when you enter and exit, and the fare is deducted from the stored balance. One card works on the subway, city buses, and most taxis across the country, and many convenience stores and vending machines accept it for small purchases too.
- Where to buy — any major convenience store (편의점: CU, GS25, 7-Eleven, emart24) or the card vending machines inside subway stations. No ID is needed for a basic card.
- Card cost — the card itself has a small one-time price that varies by design and type; character and limited-edition designs cost more than the plain card. The balance you load is separate.
- Alternatives — you may also see Cashbee (캐시비) cards with similar coverage. For most newcomers a standard T-money card is the simplest choice, since it is the most widely sold and supported.
Topping up (충전) and checking your balance
Loading money onto the card is called chungjeon (충전), and there are two everyday ways to do it:
- Convenience stores — hand the card to the staff with cash and say "chungjeon" (충전해 주세요). It takes seconds.
- Station machines — every subway station has top-up machines with an English menu. Note that many of these machines accept cash only, so it's worth keeping some bills on you early on.
Your remaining balance flashes on the gate display each time you tap, and any top-up machine can show it. If you register your card in the T-money app, online top-up and balance tracking become available for some card and phone combinations — options vary, so check the app for what your setup supports.
Subway and bus basics — and the transfer discount (환승)
Subway: tap in at the gate, tap out at your destination. Fares are distance-based, so the exit tap matters. If your balance runs short, there are top-up machines inside the paid area near the gates. Lines are numbered and color-coded, and station signs include English.
Buses: tap the reader when you board and tap again when you get off. On buses the exit tap is easy to forget, but it is what makes the transfer system work in your favor.
The transfer discount (환승 할인) is the part that surprises newcomers: when you switch between bus and subway (or bus and bus) within a set time window using the same card, the system treats it as one continuing journey rather than charging a full new base fare — you generally pay only for the additional distance. The exact time windows, transfer limits, and fare rules vary by region and are adjusted over time, so treat this as the general principle and check current local rules if you commute across systems daily.
Taxis, night buses, and late-night travel
Trains do not run all night. Last departures vary by line and day of the week — generally around late evening to midnight — so check your route in an app before a late night out.
- Taxis — plentiful and metered. Most riders book through the Kakao T app, which shows the route and fare estimate and removes the language barrier; most taxis accept credit cards and T-money. Demand spikes right after the last trains leave.
- Night buses in Seoul — Seoul runs late-night "owl buses" (올빼미버스, routes starting with N) along major corridors after the subway closes. Coverage is limited to main arteries, so check whether a route passes near you.
- Route apps — Naver Map and Kakao Map handle door-to-door transit directions (Google Maps is limited for directions in Korea), and dedicated subway apps like Kakao Metro or Subway Korea add timetables, first/last train times, and which car to board for the fastest exit.
Mobile T-money, passes, and etiquette locals notice
Mobile T-money lets your phone act as the card, with top-up from the app. Support depends on your phone and carrier setup — Android phones with a Korean SIM have the widest support, while options for other phones have been changing — so check the current T-money app offerings for your device. If you don't have a Korean number yet, start with our SIM card & phone guide, since a Korean SIM unlocks most transit app features.
Passes and rebate programs exist — Seoul has offered an unlimited-ride pass (기후동행카드, the Climate Card) and there are nationwide commuter rebate schemes such as K-pass (K-패스). Offerings, coverage, and conditions change, so compare the current options against your actual commute before committing to any pass.
- Let passengers off before boarding — queue at the floor markings.
- Leave the priority seats (노약자석) and the pink pregnancy seats empty unless they apply to you, even when the car is crowded.
- Keep phone calls short and quiet; carry your backpack in front at rush hour.
- Don't hold or push through closing gates or doors — the next train or bus is rarely far behind.
One nice thing about arriving in Korea: getting around is the cheap, easy part of settling in — the expensive part is usually furnishing an empty apartment. Monthly rental (렌탈) of appliances and furniture keeps your move-in light; the first-month settling-in checklist covers how that fits into your setup sequence.
Frequently asked questions
Do I need a T-money card, or can I use my foreign bank card at the gates?
Plan on getting a T-money card. Foreign contactless bank cards are not broadly accepted at subway gates and bus readers, and single-ride tickets from station machines are slower and less convenient for daily use. A T-money card costs little, needs no ID, and works nationwide.
What happens if I forget to tap out of the bus?
You can lose the transfer discount for the next leg, and on some routes the system may charge the maximum fare for that line since it can't tell where you got off. Make the exit tap a habit — it keeps every journey priced correctly.
Does T-money work outside Seoul?
Yes — T-money is accepted on subways, city buses, and most taxis in cities nationwide, which is why it's worth getting even if you don't live in the capital. A small number of rural bus routes handle fares differently, so carry a little cash when traveling far off the main corridors.
