Seoul subway T-Lockers store a small bag from 2,200 KRW for the first 4 hours on weekdays at 232 stations, and a small locker costs 10,200 KRW for a full 20-hour day.
That price gap is why the first thing to decide is not where but how long — under 4 hours the base fee is all you pay, past that an hourly charge starts.
This post covers locker sizes against your suitcase, weekday vs weekend fees, payment steps, the stations with the most lockers, and staffed alternatives.

luggage storage Seoul: what it costs at a subway T-Locker
The T-Locker network at 232 Seoul Metro stations is the default answer — 337 locker banks with 5,590 lockers in total.
On the operator’s 2026-09-20 price table, a weekday small locker is 2,200 KRW for the first 4 hours plus 500 KRW per extra hour.
A small locker stored for a full 20-hour day costs 2,200 + 16×500 = 10,200 KRW, and a large one runs 4,400 + 16×1,000 = 20,400 KRW.
Before anything else I check the locker size against my suitcase and the weekday vs weekend base fee, then find the station exit.
Free-locker counts change hourly, so check the live availability page rather than a saved article.
| Small locker, weekday base | 2,200 KRW (first 4 hours) |
|---|---|
| Small locker, extra hour | 500 KRW |
| Small locker, full 20-hour day | 10,200 KRW |
| Medium locker, weekday base | 3,300 KRW + 800 KRW/hour |
| Large locker, weekday base | 4,400 KRW + 1,000 KRW/hour |
| Large locker, full 20-hour day | 20,400 KRW |
Locker sizes and prices: will my suitcase fit?
Small lockers are 30 cm wide × 50 cm deep × 60 cm high, and the large 90 × 60 × 60 cm units take a big check-in suitcase.
| Size | W × D × H (cm) | Weekday base (4 hrs) | Weekend base (4 hrs) | Extra hour |
|---|---|---|---|---|
| Small | 30 × 50 × 60 | 2,200 KRW | 3,100 KRW | 500 KRW |
| Medium | 45 × 60 × 60 | 3,300 KRW | 4,600 KRW | 800 KRW |
| Large | 90 × 60 × 60 | 4,400 KRW | 6,100 KRW | 1,000 KRW |
If your suitcase is over 20 inches, the large locker is the option that actually fits it; a backpack or small day bag fits the small size with room to spare.
How to use a T-Locker: app, payment, collecting
You need the T-Locker app: install it, scan the QR code on the locker bank, choose a locker, pay the base fee and set a password on the lock.
Payment happens in two steps — the base fee when storing, and the extra fee at collection if you stayed past 4 hours.
Weekday hours run 05:00–01:00, and the machines accept VISA, MASTER, AMEX, JCB, Diners, DISCOVER plus PAYCO, KakaoPay, NaverPay, KB Pay, WeChat Pay and UnionPay.
To collect, open the app, select your locker, pay any extra fee, enter your password, and take the bag.
Which stations have the most lockers?
Hongik Univ.
Station has 171 lockers — the most in Seoul, 63 more than Anguk’s 108.
Hyehwa (128), Myeongdong (126), Jamsil (125), Gwanghwamun (118), Dongdaemun History & Culture Park (109) and Olympic Park (106) follow.
With 5,590 lockers across 337 banks, an average bank holds about 16.6 lockers, so the big stations hold roughly ten banks’ worth.
If your sightseeing route passes Hongik Univ., Hyehwa or Myeongdong, those are the easiest places to find an open unit mid-day.
Staffed storage: T-Luggage desks, Bounce, Linkeep, Radical Storage
If you want a person rather than a machine, T-Luggage desks at Seoul Station, Gangnam, Myeongdong, Jamsil, Jongno-3ga, Suseo and Gimpo Airport charge from 3,000 KRW per 4 hours for a roughly 20-inch bag, 09:00–22:00.
Bounce runs staffed spots near Seoul Station and Jongno-3ga from 5,200 KRW per bag per day, with US$10,000 protection and free cancellation — cheaper than a full weekday on a small locker (10,200 KRW), with no hourly fees to track.
Linkeep offers app-based storage with QR check-in and photo verification, while Radical Storage partners near Yongsan/Samgakji advertise about 5,100 KRW per bag/day.
The deciding factor is size: T-Luggage desks cap at about 20 inches, so for a large check-in suitcase I would use a large T-Locker (20,400 KRW weekday full day) rather than the staffed desk.
What you cannot store in a subway locker
The operator’s prohibited list covers cash, securities and valuables over 100,000 KRW, weapons, drugs, explosives and flammables, smelly or perishable food, animals, and anything over 30 kg or so large it forces the door shut.
If your bag holds anything from that list, the machine is not an option regardless of size or price.
What happens to luggage left past the 01:00 closing time is not confirmed anywhere, so plan to collect the same day.
