Intro 🚌
The Korean bus system is highly segmented, which can feel quite complex for foreigners who have just started living here. Are you wondering "Why do the buses have different colors?" or "Where should I tag my card?" In this post, we’ll cover the features of each bus type and essential etiquette so you can travel anywhere in Korea with confidence.
Quick Summary
Korean buses are categorized by color: Blue, Green, and Red.
Generally, you board through the Front Door (Ammun) to tag your card and exit through the Back Door (Dwinmun), tagging again to receive transfer discounts.
What are the differences between bus colors in Korea?
Buses in Korea are color-coded based on their travel distance and destination, making it easy to identify their purpose from a distance.
Blue : These run along major arterial roads connecting distant areas within Seoul and use three-digit numbers.
Green : These are short-distance routes connecting major subway stations or blue bus stops. Jiseon buses have four digits, while Village (Maeul) buses use the district name with a short number. For example, Jongno 07 (종로 07), which has a district name followed by a number, is a Village bus that navigates through narrow neighborhood alleys.
Red : These are express buses that quickly connect Seoul with neighboring cities like Gyeonggi-do. They use four-digit numbers and have the highest fares.

What is the bus numbering system and how can I check routes?
Bus numbers indicate the zones of departure and arrival, and using a dedicated navigation app is essential for accurate route checking.
Korean bus numbers are not random; they are created by combining zone numbers of Seoul’s eight districts. However, instead of memorizing them, it is much more efficient to use smartphone apps that provide real-time locations and arrival times. We strongly recommend using Kakao Map (Kakao Maep), which is far more accurate than Google Maps in Korea. You can find more detailed transportation tips in the Enkostay Kakao Navigation Guide.
What public transport etiquette should I follow when riding a bus?
The most important rules are boarding through the front and exiting through the back, and timing the stop bell correctly before your destination.
Tagging the Card: Tagging your card upon boarding is mandatory. You must also tag it at the rear door terminal when getting off to receive a Transfer Discount (Hwanseung Harin) for your next ride.
Stop Bell: You must press the bell on the wall before reaching your stop so the driver knows to pull over. If the bell isn't pressed, the bus may skip the stop.
Safety: It is safer to move only after the bus has fully stopped. However, because Korean buses exit quickly, it is common practice to move toward the door just before arriving at the stop.
