Seoul Subway Lockers: Sizes, Prices and Suitcase Storage
Seoul Subway Lockers: Sizes, Prices and Suitcase Storage
Seoul's T-Locker and staffed T-Luggage services solve different storage problems. This guide compares locker dimensions, current base fees, suitcase fit, payment, retrieval, and the operating-hour trap.
For self-service storage, choose a T-Locker by measured dimensions and finish retrieval before the subway service closes; for staffed suitcase storage, compare T-Luggage instead. The official Seoul guide lists T-Locker hours as 5:00 a.m. to midnight and warns that belongings cannot be retrieved outside operating hours.
Question answered: Which Seoul subway storage service fits my suitcase, what will it cost, and how do I retrieve it?

Why This Matters
A locker marked large is not a promise that every hard-shell suitcase will fit. Wheels, handles, depth, and a crowded station can turn a simple plan into a missed reservation, so compare actual dimensions before paying.
T-Locker and T-Luggage have separate price tables and service styles. Keeping them distinct prevents visitors from quoting the staffed-storage fee for a locker or expecting counter help at an unattended unit.
What To Know First
- Official T-Locker dimensions are listed as width by depth by height: small 50 x 30 x 60 cm, medium 50 x 45 x 60 cm, and large 50 x 90 x 60 cm.
- A cabin bag may fit medium, while a large suitcase may need a large locker, but measure the case including wheels and handles. Shape matters as much as advertised suitcase size.
- The official guide lists 5,557 T-Lockers at 336 locations across 273 stations. Availability is not guaranteed at the station or time you choose.
- New T-Lockers use the Korean-language T-Locker app for availability, payment, storage, and retrieval. Older locker interfaces can differ.
- T-Luggage is a staffed storage and delivery service at selected stations, not another locker size. Its locations and hours differ by branch.
- Base charges cover four hours; additional hourly charges apply. Weekday and weekend prices differ in the official table.
How To Use This In Korea
- Measure your bag before leaving the hotel, including wheels and protruding handles. Compare those measurements with the official width, depth, and height rather than relying on labels such as carry-on.
- Check the official Seoul page for the current station, service type, operating hours, and fees. Choose T-Locker for self-service or T-Luggage when a staffed counter better suits the bag or route.
- At a T-Locker, confirm that the compartment is empty and undamaged, then follow that unit's app or screen workflow. Verify the locker number before closing the door.
- Pay only after confirming the displayed service period and total. Save the app screen, receipt, password, QR code, or other retrieval credential immediately.
- Test that the door has locked. Take a photo of the locker bank, station name, floor, nearby exit, and locker number so you can find the same unit later.
- Return with enough time before midnight or the branch closing time. Follow the retrieval prompt and check the compartment before ending the transaction.
- If the bag does not fit, do not force the door. Cancel according to the displayed rule and compare a larger locker, T-Luggage, or another official storage option.
Common Mistakes
- Comparing suitcase height with locker height while ignoring locker depth.
- Mixing T-Locker prices with the separate T-Luggage price table.
- Storing a passport, medicine, or same-day transport ticket that may be needed before retrieval.
- Returning after the retrieval cutoff because the station building still appears open.
- Closing the locker before saving its number and retrieval credential.
First-Timer Tips
- Use one locker for items you can safely leave and keep documents, medicine, batteries, and valuables with you.
- A photo of the station exit and locker bank is more useful than a locker number alone in a large interchange.
- Check weekend pricing when planning Saturday or Sunday storage, not only the weekday figure shown first.
- For multiple large bags, compare staffed storage with paying for several large lockers.
- Build a time buffer because available compartments may be in another part of the station.
Before You Go
- Measure every bag in centimeters.
- Confirm T-Locker or T-Luggage.
- Check weekday or weekend pricing.
- Confirm closing and retrieval time.
- Prepare a compatible payment method.
- Keep essentials and valuables outside the locker.
