Korea Subway Locker Luggage Storage Travelers in Korea: Practical Guide for Foreign Travelers

Quick answer

Korea’s subway lockers (사물함, samulham) are a convenient way to store luggage while exploring between hotel check-in/out or before a flight. Major subway stations in Seoul (e.g., Seoul Station, Myeongdong, Hongdae, Gangnam) and other cities have coin-operated or card-operated lockers. Sizes range from small (backpack) to large (29-inch suitcase). Payment is typically by T-money card, credit card, or cash (coins). Lockers are usually available from around 5:00 AM to midnight, but some stations have 24-hour access. Expect to pay about 2,000–5,000 KRW for 4 hours, with additional fees for extended use. Always check the specific station’s operating hours and payment methods before depositing luggage.

Best route

Where to find subway lockers

Lockers are located near ticket gates, in transfer corridors, or near station exits. Look for signs saying “사물함” (samulham) or “Locker.” Major stations with large locker banks include:

• Seoul Station (서울역) – near exits 1, 4, and the AREX transfer area.
• Myeongdong Station (명동역) – near exits 2 and 3.
• Hongdae (Hongik Univ.) Station (홍대입구역) – near exits 1, 2, and 8.
• Gangnam Station (강남역) – near exits 3, 4, and 9.
• Incheon Airport Terminal 1 & 2 – also have lockers (but airport storage is separate).

How to use a locker

1. Find an available locker – Look for a green or unoccupied indicator.
2. Choose size – Small (approx. 34x45x60 cm), Medium (42x60x80 cm), Large (60x90x80 cm).
3. Pay – Insert T-money card, credit card, or coins. Some newer lockers accept mobile payment (KakaoPay, Naver Pay).
4. Set a temporary password – You’ll be prompted to create a 4-6 digit PIN. Write it down or save it.
5. Store luggage – Close the door and confirm it’s locked.
6. Retrieve – Enter your PIN. If you exceed the paid time, you may need to pay extra before opening.

Timing and tickets

Operating hours

Most subway station lockers are accessible during station operating hours (typically 5:00 AM – midnight). Some stations with 24-hour exits or transfer areas have lockers available 24/7. For example, Seoul Station’s lockers near the AREX transfer area are accessible 24 hours, but lockers near other exits may be gated after the last train.

Fees (approximate, subject to change)

Maximum storage time is usually 24 hours. After that, the locker may be cleared and items moved to a lost-and-found center.

Payment methods

• T-money / Cashbee card – Most common. Tap to pay.
• Credit/debit card – Visa, Mastercard, etc. accepted at many lockers.
• Cash (coins) – Some older lockers only accept 100, 500, and 1,000 KRW coins.
• Mobile payment – KakaoPay, Naver Pay, Samsung Pay on newer lockers.

Tip: If you only have cash, break larger bills at a convenience store or ticket machine before using the locker.

Photo plan

If you want to document your luggage storage experience, take a photo of the locker number and the screen showing your PIN (without revealing the PIN). Also snap a picture of the station exit or landmark near the locker so you can find it easily later.

Mistakes to avoid

1. Not checking operating hours – If you leave luggage after the station closes, you may not be able to retrieve it until the next morning. Always confirm the locker area’s access hours.
2. Forgetting your PIN – Write it down or save it in your phone. There is no “forgot PIN” option; you may have to wait for staff assistance.
3. Using the wrong size – A large suitcase won’t fit in a small locker. Measure your bag before paying.
4. Overfilling – If the door doesn’t close properly, the locker may not lock. Use a size up.
5. Leaving valuables – Lockers are not insured for high-value items. Keep passports, money, and electronics with you.
6. Ignoring time limits – Exceeding the paid time may incur extra fees or cause your items to be removed.
