How do you know which subway exit to take in Korea?

Korean subway stations number every exit, and the closest one depends on where you're headed. Search your destination in a map app before you get off and it will usually tell you which exit number to use.

How do you find the right exit number?

Map apps often tell you the nearest exit number once you search your destination. Doing this before you get off the train is the most reliable way to know.

What if you can't find your way inside the station?

Stations have signs throughout showing exit numbers and directions. Just follow the number printed on the sign.

What should you actually do?

1. Search your destination in a map app before getting off to check the exit number
2. Follow the exit number and direction shown on station signs
3. Give yourself extra time at stations with long transfer corridors or many exits
4. Once outside, recheck your direction with the map app

Stations with long transfer passages or many exits can get confusing, so it helps not to rush.
