A schematic route guide, with an official live network link
Find the stop in both directions
A bus number alone is not enough. The same route can use opposite sides of the road. Match the stop name, travel direction and stop ID in the map app or on the pole. Check the live display before boarding.
The diagrams above explain the bus categories. They do not show a complete network or a numbered service you should board. For Namsan and airport buses, check the current service separately.
