Yes, there are lockers, and they are in nearly every subway station in Seoul. Seoul Metro counts 5,557 of them across 273 stations, in three sizes, and a large one that takes a full suitcase costs 4,400 won for four hours on a weekday.

You do not need an app, an account or a Korean phone number. You need a bag that fits and a way to pay at the screen. The rest of this page is the fine print that decides whether your afternoon goes smoothly: which size really fits which bag, what weekends cost, and what to do when the bag is bigger than any locker.

Every number here comes from Seoul Metro’s own locker and luggage pages, read on 1 September 2026.

What it costs

Look for the sign 물품보관함 (mulpum-bogwanham, “item storage box”). Seoul’s are branded 또타라커 (ttota-rakeo, “T-Locker”).

Size Weekday, 4 hours Weekend and holiday, 4 hours Each extra hour
Small (S) 2,200 won 3,100 won 500 won
Medium (M) 3,300 won 4,600 won 800 won
Large (L) 4,400 won 6,100 won 1,000 won

The four hours are a minimum, not a block you buy again. After that the meter runs by the hour at the rate in the last column, weekday or weekend alike.

Lockers work from 05:00 to midnight every day, including weekends and holidays. Outside those hours you can neither store a bag nor take one out, so a bag left at 23:30 stays until 05:00. If you never come back, the contents are kept for a month and then donated or thrown away.

Something jammed, or the screen will not give your bag back? The call centre is on 1877-1265 or 1670-4302, from 06:00 to midnight, and someone comes out within two hours. If the fault was yours, that visit is charged.

Which size fits which bag

The three lockers are all 50 cm wide and 60 cm deep. Only the height changes: 30 cm for small, 45 cm for medium, 90 cm for large.

Small is 30 centimetres tall and takes a cabin bag lying flat. Medium is 45 centimetres tall and takes a backpack or a fat cabin bag. Large is 90 centimetres tall and takes a checked suitcase standing upright. A cabin bag is shown at 55 by 40 by 20 centimetres, the economy limit Asiana Airlines publishes.

Small takes a cabin bag lying down. A checked case goes in large, standing up.

A cabin bag is the easy case. Airlines cap it around 55 × 40 × 20 cm (that is Asiana’s economy limit), and lying flat it slides into a small locker with room to spare.

A checked suitcase does not lie down in any of them, because 60 cm of depth is shorter than the case. It stands up instead, and only the large locker is tall enough. Do not buy a medium for a suitcase. At 45 cm tall it holds a backpack, a duffel, or a cabin bag on its side, and that is all.

The width is the same 50 cm everywhere, so two thin bags side by side in one locker is fine. Two suitcases are not.

Paying at the screen

Walk up, touch the screen, pick a free door, pay, and the door opens. Retrieval is the same screen with the code or card you used. Older lockers at some stations work slightly differently, and the instructions on the machine take priority over anything written here.

Seoul Metro’s pages do not list which cards the touchscreen accepts, and we have not been able to confirm that a card issued abroad works on it. Carry enough won in cash for the locker before you rely on one. Korean sites and machines are a separate world from tapping a card in a shop; the foreign card guide explains why.

The T-Locker app (또타라커 in the app stores) runs in English, Japanese, Korean and Simplified Chinese and lets you check which stations have free lockers and reserve one. The operator lists credit card, bank transfer and mobile payment as the ways to pay in it. Visitors report that it refuses to create an account without a Korean phone number, which is the same wall described in the phone verification guide. So treat the app as a nice extra, and the screen as the plan.

Bigger than a locker, or longer than a day

Seoul Metro also runs staffed luggage rooms called 또타러기지 (ttota-reogiji, “T-Luggage”) at six stations. This is where a 28-inch case, a bag you want held for three days, or a group’s worth of luggage goes.

Station Where
Seoul Station (Line 1) B1, towards exit 1
Hongik University (Line 2) B1, towards exits 3 and 4
Jamsil (Line 2) B1, towards exits 3 and 4
Myeongdong (Line 4) B1, towards exits 9 and 10
Gimpo Airport (Line 5) B1, towards the I-Center
Jongno 3-ga (Line 5) B1, towards exit 6

They price by suitcase size, in inches, for the first four hours, then 1,000 won an hour on top whatever the size and the day.

Suitcase Weekday, 4 hours Weekend, 4 hours
S, up to 20 inches 3,000 won 4,000 won
M, 20 to 23 inches 4,000 won 6,000 won
L, 23 to 27 inches 6,000 won 9,000 won
XL, over 27 inches 9,000 won 13,000 won

Open 09:00 to 22:00 every day, walk-in, or book at tluggage.co.kr. A cabin bag costs slightly more here than in a locker, but a human takes it, there is no door to fit, and nobody minds an odd shape.

The same counters deliver luggage the same day. Between any two of those stations, a bag up to 23 inches is 17,000 won on a weekday and 25,000 won at the weekend. Between a station and Incheon Airport it is 20,000 and 29,000 won. Larger cases run 26,000 to 45,000 won. The point of the airport run is the morning of your flight: hand the case over in Hongdae or Myeongdong, spend the day with nothing, collect it at the terminal.

At Incheon Airport

Both terminals have staffed storage counters run by private operators, which charge by case size and by the day. We could not find their current prices on an official page, so ask at the counter before handing anything over. If you are only in Seoul for a stopover, the cheaper move is often to ride into town and use a station locker or a T-Luggage room there.

Busan

Busan’s subway has lockers too, and they are cheaper but less uniform. The base period is three hours, not four. On Line 1 that is 2,000 won small, 3,000 medium, 4,000 large and 6,000 extra-large. Lines 2, 3 and 4 use different operators with their own sizes and prices, Line 2 has no medium at all, and the hourly overrun differs by line. Busan Transportation Corporation’s locker list, checked 1 September 2026, has the per-station detail.

One rule holds in both cities. Note the time you locked the door, and be back before midnight.

Common questions

How much is a subway locker in Seoul?

For four hours on a weekday: 2,200 won small, 3,300 won medium, 4,400 won large. Weekends and holidays cost 3,100, 4,600 and 6,100 won. Every extra hour adds 500, 800 or 1,000 won by size. Figures from Seoul Metro's locker page, checked 1 September 2026.

Will my suitcase fit?

A cabin bag fits the small locker lying flat. A checked suitcase needs the large locker, which is 90 cm tall, so the case stands upright. The medium locker is 45 cm tall, which suits a backpack or a fat cabin bag, not a checked case.

Can I leave a bag overnight?

Yes, and you pay by the hour for the whole time. The catch is access: lockers open from 05:00 to midnight, and you cannot get your bag out in between. Anything left past its time is kept for up to a month, then given away or thrown out.

What if my bag is too big or I need it for days?

Use a T-Luggage counter. Seoul Metro runs staffed luggage rooms at six stations, including Seoul Station, Hongik University and Myeongdong, priced by suitcase size from 3,000 won per four hours. They also deliver bags the same day between stations or to Incheon Airport.

Do I need a Korean phone number?

Not for the locker itself. You pay at the touchscreen. The T-Locker app runs in English, Japanese and Chinese and lets you reserve ahead, but visitors report it will not create an account without a Korean number, so treat the app as optional.
