Which Seoul Subway Stations Actually Have Luggage Lockers

Major stations that reliably have lockers

• Seoul Station: one of the best-covered stations, with multiple locker banks across different exits and sizes, reflecting its role as a KTX and airport-rail hub.
• Gangnam Station: generally good coverage given its size and foot traffic, though larger-size lockers can sell out on busy afternoons.
• Myeongdong Station: solid coverage near the main shopping exits, useful for a shopping-heavy day trip.
• Hongik Univ. Station: decent coverage, though lockers here fill up faster on weekend nights given the nightlife foot traffic.
• Dongdaemun History & Culture Park / Dongdaemun Station: reasonable coverage tied to the area's market and shopping traffic.

Where coverage is thinner than expected

Smaller or less central stations -- even ones that see real tourist traffic, like some stops near secondary attractions -- may have only a handful of lockers or none at all. Locker availability is not evenly distributed by station importance; it correlates more closely with transfer-hub status and historical foot traffic than with tourist popularity specifically.

What to do if lockers are full

1. Check a locker-finder app or the T-Locker app, which shows real-time availability by station rather than making you walk to check in person.
2. Nearby convenience stores at some stations offer informal short-term storage for a fee -- ask if station lockers are full.
3. Larger terminal stations (Seoul Station, major KTX hubs) are the most reliable fallback if your first-choice station is full, even if it means a short extra subway ride to drop bags.
4. If you're storing bags for more than a day, confirm the specific locker's maximum-duration rule before you lock up -- some station lockers auto-flag or clear contents after 24-72 hours.
