The Secret Navigation Tool Locals Always Use

Ask a Korean local for directions and you'll almost certainly hear something like: "Get off at Gangnam Station, Exit 5." Subway exit numbers are a fundamental part of how Koreans give and receive directions — and understanding them will dramatically improve how you navigate Korean cities.

Why Exit Numbers Are So Important

Major subway stations in Korea can be enormous underground complexes spanning an entire city block or more. Gangnam Station in Seoul, for instance, has over 10 exits spread across several hundred meters. Coming out the wrong exit can leave you walking 10–15 minutes in the wrong direction. Exit numbers eliminate that confusion instantly.

Businesses, restaurants, and offices routinely list their nearest subway exit in their address or contact information. You'll see listings like:

"2호선 강남역 10번 출구 도보 3분" — Line 2, Gangnam Station, Exit 10, 3-minute walk.

How Exit Numbering Works

Exit numbers in Korean subway stations are assigned in a clockwise direction starting from Exit 1, which is generally positioned at the north or the main entrance. The numbering increases as you move clockwise around the station perimeter. This means:

  • Exits 1–3 are often on the same side (e.g., north/east)
  • Higher-numbered exits are progressively around the other sides
  • Transfer stations with multiple lines may have a large number of exits (some have 15+)

How to Find the Right Exit Before You Go

  1. Check the venue's website or Naver Place listing — most businesses list their nearest exit.
  2. Use Naver Maps or Kakao Maps — enter your destination and the app will tell you exactly which exit to use and show you the walking route from that exit.
  3. Look at the subway station map — inside every station, color-coded maps show what landmarks and streets are accessible from each exit.
  4. Use the Seoul Metro app or SMRT app for detailed in-station navigation including transfer routes.

Reading Exit Signage Underground

Inside Korean subway stations, exit signs are color-coded and clearly posted at every junction. Key things to know:

  • Exit signs appear as white numbers on green backgrounds in Seoul Metro stations.
  • Arrows indicate the direction you need to walk toward that exit.
  • Each exit often has a small list of nearby landmarks posted beside the number (in Korean and sometimes English).
  • Transfer lines are indicated with the line's color and name at the platform level.

Practical Tips for Tourists and Newcomers

  • Screenshot the exit info before entering the subway — internet can be slow underground in older stations.
  • Note both the station name AND the exit number when saving a location. One without the other is only half the information.
  • If you exit at the wrong number, don't panic — you can re-enter within a few minutes and your fare won't be charged again (within the free transfer window).
  • For large stations like Seoul Station, Express Bus Terminal, or Hongik University Station, allow extra time — these are complex hubs with many interconnected lines.

Beyond Seoul: Exit Numbers Nationwide

The exit numbering convention applies throughout Korea's metropolitan subway systems — not just Seoul. Busan Metro, Daegu Metro, Incheon Metro, and Gwangju Metro all follow the same clockwise numbering convention, so once you understand the system in one city, it translates everywhere.

Conclusion

Subway exit numbers are one of Korea's most practical urban navigation tools. Treat the exit number as an essential part of any address or meeting point, and you'll navigate Korean cities like a pro from day one.
