I entered the wrong subway gate
Checked 2026-08-03 · Official sources
01
What happened
You may be inside the paid area on the wrong platform or in a section with no internal passage to the other direction.
02
What to do now
- First, follow signs for the opposite platform and check whether there is an internal passage.
- If there is no passage, do not repeatedly tap through different gates.
- Use the intercom or find station staff and show the message below.
- Some listed Seoul sections allow re-entry within 15 minutes, but this is not guaranteed across the whole network. Ask staff before relying on it.

개찰구를 잘못 들어왔어요. 반대편 승강장으로 가고 싶어요.
I entered the wrong gate. I need to reach the platform in the opposite direction.
03
What it may cost
You may be charged another base fare if you exit and re-enter outside an eligible re-entry section. Ask staff before tapping out when possible.
04
How to avoid it next time
- Check the terminal station or next-station name shown above the gate.
- Use the platform direction, not only the line number.
- At split platforms, confirm the direction before tapping in.
