What the bus colours mean (Seoul)
- Blue: trunk buses on long routes along major roads, often in central bus lanes.
- Green: branch buses that link neighbourhoods with subway stations.
- Red: wide-area express buses between Seoul and surrounding cities, with fewer stops.
- Yellow: short circular routes in central areas.
Other cities use their own colours and route numbers, so check the route in a map app.
Getting on and off
- Board at the front door and tap your transit card (T-money, WOWPASS or the Climate Card in Seoul) on the reader.
- Exit by the back door and tap again when you get off — this is what gives you the transfer discount.
- Don’t rely on cash: some buses no longer take it, and drivers can’t always give change. See Seoul subway & T-money for getting a card.
- Fares differ by bus type; the reader shows what was charged.
Transfers between bus and subway
With the same transit card, bus-to-bus and bus-to-subway transfers within the allowed time are counted as one journey. Tap on and off every time — if you forget to tap off the bus, you lose the transfer.

Knowing when to get off
Screens and announcements (often in Korean and English) show the next stop. Press a red stop bell before your stop, then stand near the back door once the bus has stopped. Hold on — buses can brake and turn sharply.

Airport buses are different
Airport limousine buses run between the airports and hotels or major areas. They are separate from city buses: luggage goes underneath, seats are reserved per passenger, and payment and stops differ by route. Compare them with AREX, taxis and pickups in Incheon Airport to Seoul.
