Seoul Station is where most travelers want luggage storage — you are either off the airport train with a full suitcase or about to board a KTX. There are two ways to do it, and which one is right depends on your bag.
1. Coin lockers
Seoul Station has 4 locker spots holding about 72 units. They are not in one bank: they sit near exits 1, 2, 3, 4 and 11, so one cluster being full does not mean the station is out.
Pricing is identical across the whole network — about ₩2,200 small, ₩3,300 medium, ₩4,400 large for the first four hours, then an hourly top-up. Self-service, no queue, cheapest option. Payment is by credit card, bank transfer or mobile carrier billing; you then have about 3 minutes to key the one-time PIN into the locker itself.
The Seoul Station locker page shows each spot with how many small, medium and large units are free right now — worth thirty seconds before you wheel a suitcase down a level.
2. The staffed desk (T-Luggage)
Staff take the bag over a counter, and the service also ships to hotels and the airport. It started at Hongik Univ. Station in November 2019 and now runs at Seoul Station, Gimpo Airport, Myeongdong, Gangnam and Jamsil as well.
The Seoul Station desk is heavily used by visitors — over 80% of its users are foreign travelers — and service runs in English, Chinese and Japanese alongside Korean.
Which one
- Locker — a backpack or one suitcase, a few hours. Cheapest and fastest.
- Staffed desk — anything that won't fit a large locker (50 × 90 × 60 cm inside), several pieces, or when you'd rather have it sent ahead.
Flying out of Incheon
The AREX airport line runs from Seoul Station, so on a last day the clean move is to store the bag here, spend the afternoon light, and collect it on your way to the train. If you would rather not carry it at all, the staffed desk can send it to the airport.
Watch the hours
Lockers run roughly 05:00 to midnight — outside that window you can neither store nor collect. If you are on a pre-dawn flight, pull the bag out the night before or check the staffed desk's own hours. And if you have gone past your paid block, the door only opens after you settle the extra charge. The step-by-step is in the full Seoul luggage guide.
