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

  1. First, follow signs for the opposite platform and check whether there is an internal passage.
  2. If there is no passage, do not repeatedly tap through different gates.
  3. Use the intercom or find station staff and show the message below.
  4. 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.

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.
