Can I use the subway with a suitcase?

We could not find an official rule that bans ordinary suitcases, but crowding and stairs matter. Stations offer lockers, and Seoul has a same-day luggage delivery service, so you can travel light.

The official pages we checked describe luggage storage and delivery, not a size limit for carrying bags onto trains. For very large or heavy items, ask the Seoul Metro customer center before you travel.

No official luggage size rule was found in the pages checked, so this answer does not state one.
