Taking city buses

Seoul city buses are color coded. Blue buses are trunk routes covering long distances, green buses are branch routes linking subway stations and neighborhoods, red buses are express routes between Gyeonggi Province and Seoul, and yellow buses circle downtown. There are also small green village buses for short local trips.

Yes. On Korean city buses you normally board at the front door and tap your card, then exit through the rear door and tap again. Press the stop button as your stop approaches, and it is safest to stand up only after the bus has fully stopped. On some express buses you exit through the front.

Many Seoul city bus routes no longer accept cash as part of the cashless bus program. Some regions still take cash, but drivers may not be able to give change. A transit card is cheaper and gives transfer discounts, so get one before you ride.

Bus stop displays show estimated arrival times for each route, and map apps also show real-time bus locations and arrival times. Check the stop's name and number so you do not mix it up with the stop across the road. Stops on opposite sides of a street often share the same name, so confirm the direction.

When the announcement for the next stop plays, check whether it is yours and press the stop button. If nobody presses it and no one is waiting at the stop, the bus may drive past. Announcements are often in Korean and English, and the screen inside the bus also shows the stop name.

Yes. Seoul runs late-night buses after midnight, and their route numbers start with N. They connect major nightlife areas with residential neighborhoods, but buses come less frequently. If you miss the last subway, search a map app for late-night bus routes.

Many passengers stand on city buses, but starts and stops can be abrupt, so always hold a handle or pole. Express buses that use highways may restrict standing passengers. When getting off, wait until the bus has fully stopped before moving to the door.

On Seoul city buses, the driver can refuse boarding if you carry a disposable cup of food or drink that they judge could cause a safety problem or bother other passengers. Not every takeaway drink is banned, but it is best to avoid anything that might spill. Finish your drink first, or carry a bottle with a secure cap.

If you tap your transit card both when boarding and when getting off, you get a transfer discount when you board another bus or the subway within the allowed time. If you forget to tap off, the discount will not apply. The time window and number of transfers can differ by region.

Seoul's trunk and branch bus numbers follow a system where the digits indicate the starting area, destination area and sequence, while circular and express commuter buses use different numbering. You do not need to memorize it, since map apps tell you which stop and number to take. Each bus shows its number and main stops on the front and side.

In rural areas and some regional tourist spots, buses may come once an hour or less. Check timetables at the terminal or stop, or ask a local tourist information center, and always note the last bus. If your schedule is tight, a taxi or tour may work better.

City buses have no luggage hold, so bringing a big suitcase can inconvenience other passengers. It may be hard to board at busy times, so an airport limousine bus or a taxi is usually better. Express and intercity buses do have luggage compartments underneath.

Yes. City buses have priority seats for seniors, people with disabilities, pregnant women and passengers with small children, placed in convenient spots near the doors. Even if you sit there when it is empty, give it up when someone who needs it boards. People also commonly give up regular seats to elderly or pregnant passengers.

Many major Seoul roads have median bus lanes with stops in the middle of the road. You cross at a crosswalk to reach the island platform, and at some stops buses going both directions stop at the same island. Always check the direction before boarding.

If no one waiting signals or steps forward, a bus sometimes drives past the stop. When many routes share a stop, move toward where your bus pulls in and signal that you want to board. You can report skipped stops or rude service to the local transport complaint service.

Tapping on and off works much the same in most cities, but bus colors, numbering and transfer rules differ by city. Jeju has express buses from or via the airport linking major areas and transfer hubs, though they do not go directly to every attraction, so check the route. Local transport apps and tourist information centers can help with details.

Short calls are fine, but keep your voice low. Public transport in Korea tends to be quiet, so loud calls or watching videos on speaker can draw disapproving looks. Use earphones for videos and music to stay considerate. Keeping conversations with friends quiet is also appreciated.

The red express buses connect Seoul quickly with Gyeonggi cities such as Suwon and Seongnam. Many routes are seated only, so when a bus is full during rush hour you may not be able to board. Some routes let you reserve a seat in advance through an app.

Low-floor buses have a lower floor and a ramp, making it easier to board with a wheelchair or stroller. Other buses have steps that can be difficult, so check map apps or stop displays to see whether a low-floor bus is coming. Let the driver know when you board so they can assist.

Right after losing something, contact the bus company that runs the route, giving the bus number, the time you rode and the direction. Found items are usually kept by the operator for a while and then handed over to the police. As of November 2026, police lost-and-found reports and searches are handled through the Police Civil Service 24 portal.
